Top Pro

Open source client apps

Client apps are open source, making whole service more trustworthy. See More

Top Con

No source code sintax highlighting

Anil Atluri's Experience

Wonderful app for safe, ads-free,no-tracking message app. See More

Top Pro

Free and convenient large file sharing

Copy/paste videos, gifs, images, geolocation, and documents, drag over files for practically any time up to 1.5GB in size. Images can be compressed, too. See More

Top Con

Not fully open source

Telegram has an open API and protocol free for everyone, but the backend software is not open source. Therefore 100% privacy can not be evaluated. See More

Top Pro

Privacy focused

In addition to the end-to-end encryption that provides privacy to communications, the app also includes self destructing timers for chats, and the ability to permanently delete messages, yours and theirs, from your device. See More

Top Con

MTProto encryption protocol may not be secure

Reasons are outlined here. See More

Top Pro

See More

Top Pro

Cloud chat keys are kept in different jurisdiction

Even though encryption used for cloud-based storage (e.g. Gmail, Facebook, iCloud) may not be as secure as end-to-end encryption or zero-knowledge storage, Telegram does the most that it can by holding keys to chats in different jurisdictions, requiring intergovernmental cooperation to obtain the keys. This is aside from whatever other security measures have been taken, of course. See More

Top Pro

Save time with inline bots and link previews

Unfortunately, on the desktop videos don't play, but images are viewable without visiting popular websites like imgur and Instagram. You can play YouTube videos and others within the app, so you don't need to embed code or anything. With inline bots, such as @gif, @pic/bing, @vid/YouTube, etc, you can look things up without leaving the client or chat that you're in. Simply type the name and some keywords and wait for the results to load. See More

iMessage is not available on anything but Apple devices. See More

iMessage

Top Con

Not cross-platform

Top Pro

Secure end-to-end encryption

NeighborlyAtlas's Experience

iMessage is an utter disaster. It can't send separate texts to anyone who is on a shared Contact record but with separate mobile phone numbers (e.g., "Paul and Angie Smith"). It merges ALL threads that ever went to ANYONE on that shared Contact record. Want to text just the husband to set up a surprise party for the wife? Not possible. iMessage will ONLY add that new text to the EXISTING thread you had with the wife. Duh! iMessage is pitifully incompetent. See More

Top Con

Can't send separate texts to individuals who share a Contact record

iMessage is an utter disaster. It can't send separate texts to anyone who is on a shared Contact record but with separate mobile phone numbers (e.g., "Paul and Angie Smith"). It merges ALL threads that ever went to ANYONE on that shared Contact record. Want to text just the husband to set up a surprise party for the wife?

Electrux Redsworth's Experience

Fun to use See More

Top Con

Blocking Spam Messages takes 3 steps more than is needed

You have to open the message, select the sender, open info on the sender, then block sender. The default Android message app, select the message, block sender. it automatically deletes the message and blocks the sender. See More

Top Pro

Supports voice messages

Short voice recordings/messages can be quickly sent, and messages can be easily dictated into written messages as well. See More

CharmingKinichAhau's Experience

Slow and messages don’t always go through. Typical apple crap. See More

Top Con

iCloud sync of message is not stable

Sometimes, the messages on different devices with the same ID will be different, the syncing function work poorly. See More

Top Pro

Free and unlimited messages over Wi-Fi and data

Messages clearly indicates whether messages are being sent over iMessage (blue) or SMS (green) where messaging rates apply. iMessages do not count as SMS messages with your carrier, instead they use a negligible amount of data to send over Wi-Fi and cellular data networks. See More

DelightfulSamshinHalmoni's Experience

Good for 2011. Not for 2019 See More

Top Con

Slow and unreliable

Top Pro

Top Pro

Apps and games for iMessage are available

For example, you can play games like pool or you can show someone a destination to go to. See More

Communications are encrypted between client and Google servers but not from sending client to receiving client. This means that there is still a possibility for someone other than the receiver to read your message if they have access to internal Google servers. But it allows also lightweight chat history search, spam protection and other features. See More

Hangouts

Top Con

Lack of end to end encryption

Top Pro

Free and cross-platform

Google offers all features of Hangouts completely free on iOS, Android and web with quick and reliable sync across all platforms. It's also tightly integrated in other Google services - it can be accessed from services such as Gmail, Google+, Chrome. While the standard Hangouts offering is completely free, there are business, education and government solutions that increase the participant count to for video calls to 15 and offers support that may cost money. See More

DelightfulSamshinHalmoni's Experience

Formally secure. Insecure in fact. Dead app. See More

Specs

Platforms:Web / iOS / Android / OSX / Chrome

End-to-end encryption:No

Audio recording:No

Hangouts uses Google account credentials. If you use any other Google service, then you already have an account set up. See More

Top Con

Poor interface

Top Pro

No need to create a separate account if you use any other Google service

Top Con

Owned by Google

Google is a corporation that earns money from collecting data and breaching privacy. See More

Top Pro

Group video support

If you have signed in your Google account, Hangouts allows making video calls with up to 10 people or one-on-one if you haven't. There are business, education and government solutions that increase the participant count to for video calls to 15 and offers support. Additionally, you can switch between either the front-facing or rear-facing camera on your phone. See More

Top Con

Buggy video calls

Whether video calls work on your device is pure lottery, and there's nothing you can do to fix it. See More

Top Pro

Free calls to US and Canada from anywhere in the world

Most calls to US and Canada are free and international calls have cheap rates. See More

Top Con

Doesn't support sending voice notes or video recordings

Top Pro

Google Voice integration

Google Voice is a service that enables making and receiving free phone calls within US. Google Voice forwards incoming calls to all connected devices and allows placing calls from any of the connected devices, but they will show as coming from the Google Voice number. Hangouts completely integrates Google Voice, allowing you to place calls and receive texts and voicemail from all of your device. See More

Top Con

Weaker compared to Android counterpart

A list of features that are in the Android version of Hangouts are missing in the iOS version. Most notably SMS support. See More

Top Pro

Excellent read receipts in group chat

It's possible to know what each and every participant of the group has read. Their icons are displayed below the last message. See More

Top Con

Poorly manages data

Doesn't cache images well either received or sent. Often users will see the sent images re-downloading, same for conversations. See More

Top Pro

Advanced status sharing

Hangouts can inform about the status of other users including what device they are currently using, whether they are in the middle of a call and when were they last seen. This allows making sure that you're not disturbing someone when initiating a conversation. It's possible to granularly turn off status sharing. See More

Top Con

SMS is not supported on web

SMS messages can only be sent from the mobile apps and they don't sync with Chrome/Gmail plugins unless originated from Google Voice. See More

Top Pro

Video tools

Hangouts can add different effects and overlays to video calls that can be viewed on your device. Unfortunately, they can't be set from your phone. See More

Top Con

No way to moderate groups

If a member of a group chat room becomes disruptive, or there's some other need, there's no way in Hangouts to remove somebody from an existing chatroom. Similarly, if somebody is no longer active, there's no way to remove that user from the chat room to make slot for new active members. See More

Viber

Top Pro

Desktop apps allow texting, calling and enable transfering calls

Top Con

Doesn't sync well

Sync awfully between Phone and PC clients. See More

DelightfulSamshinHalmoni's Experience

Super insecure. Share messages with the governments. Has access to the private keys ("real" end-to end encryption) Extremely not optimized for battery use. Crappy UI. See More

Specs

Platforms:Android / iOS / WP / BB / Symbian / Windows / OSX / Linux

Viber is tied to your phone number so it can quickly see who else in your contacts list is using the application. See More

Top Pro

See who of your contacts is using Viber quickly

Top Con

Has multiple a security vulnerabilities

EFF gave Viber's security 1 out of 7 points in November, 2014. It deducted points because the provider is capable of reading encrypted messages, there's no way to verify contacts identities, past communications are not secure if encryption keys are stolen, the code is not open to independent reviews, the security design is not properly documented and there has not been a recent code audit. See More

Top Pro

Combines cellular and data messaging

This has an advantage in that if you text someone who uses Viber it will be free, if not it will just revert to SMS. This means you can replace your standard messaging app with Viber as well. See More

Top Con

Shady company

Top Pro

Public chats

It's possible to be a fly on the wall on other group or one-to-one chats that have been opened up to the public. These public chats are often promotional chats with celebrities. See More

Top Con

Potential spyware

Viber communication's aren't end-to-end encrypted. The company has access to the key that the communication's are encrypted with. See More

Top Pro

Supports 200 person group chat

Viber allows creating groups of up to 200 people on the iOS version of Viber. It also has a cool "smart notifications" feature to prevent being overwhelmed with notifications if a lot of people are active in a chat group. See More

Top Pro

Completely free and ad-less

Viber uses data connection and the app is free. There are also no advertisements. See More

Top Con

Proprietary Software

Not Open Source. See More

Top Pro

No need to create an account or add contacts

One of the best things about Viber is how it handles setup and sending messages. Viber uses your existing number as your ID, so you don't need to create a separate Viber account. See More

Top Con

The company evades U. S. tax

Top Pro

Supports voice calls

Viber has really well implemented voice tech. It has comparable quality to Skype and you can even tranfer calls from your phone to your desktop seamlessly. See More

Top Pro

Clean interface

The interface is simple, functional and intuitive. See More

WhatsApp shares your messaging meta data with Facebook if you do not opt-out in the settings. If you use the same phone number for WhatsApp and Facebook, the profiles can easily be linked. See https://www.whatsapp.com/faq/en/general/26000016 See More

WhatsApp

Top Con

Specs

Platforms:Android, iOS, Web, Mac, Windows, Windows Phone

Not open source. See More

Top Con

Proprietary

Top Pro

Straightforward interface

The interface is very simple, fast and easy to use. WhatsApp does a great job of focusing on the basics behind messaging. The app is simple to use, fast & very polished. You can start using it as soon as the app has been downloaded - it does not require setting anything up or registering. You can communicate with anyone in your contacts list that also uses WhatsApp. Includes useful features like seeing when a contact is currently available or typing. See More

Anthony's Experience

Excellent app to use. See More

Top Con

Not a multi device app

No support for the iPad, the app has support for possibly all Android tablets but only the iPhone on the iOS platform can install WhatsApp. See More

Top Pro

End to end encryption in all messages and calls based on Signal protocol

CreativeCermait's Experience

whatsapp delete files 3 days after sending. whatsapp force you to download files before forwarding them. whatsapp dont have channels. whatsapp adding new contact need 3 clicks. its unfriendly. whatsapp is run by facebook (us company) which will send user data to us government. It dont care about people privacy. whatsapp dont allow large files. whatsapp group size is limited. See More

Top Con

Single device

You cannot use the same WhatsApp account on multiple devices (e.g. a tablet, a PC and a cellphone). The account is tied to the device with the specific cellphone number. Chat history is deleted when you sign in to a new account, unless you have created a backup. See More

Top Pro

Effortlessly builds your contacts

WhatsApp will automatically find all of your contacts currently using Whatsapp and add them to your contacts. This makes it really easy to setup and given that it's the most popular messaging app it's likely that a lot of your contacts are already using it. See More

DelightfulSamshinHalmoni's Experience

One reason for keep it on my phone is it's huge popularity. See More

Top Con

Web interface uses message mirroring

To use your computer to send messages your phone must be on with a consistent data connection. See More

Top Pro

Web, Mac, and Windows apps

WhatsApp can be used from the desktop via the web app (web.whatsapp.com), the Mac app, or the Windows app. See More

Anil Atluri's Experience

I hate the proposed ads to appear. See More

Top Con

Limitation on shareable file sizes

WhatsApp now allows users to share files of any type, but there is still a 16 MB size limit. See More

Top Pro

Message mirroring on web app

WhatsApp can be used from the desktop via Chrome, Firefox and Opera browsers. Accessing it requires using the Android app to scan the QR code that's presented on web.whatsapp.com. See More

Top Con

Hard to migrate history cross platform

Migrating your chat history from Android to iOS or the other way around is not so simple. In some cases it requires a 3rd party app and in some the only way is to migrate specific chats one by one. See More

Top Pro

One-on-one texts can be encrypted

WhatsApp has implemented end to end encryption for messages sent on it's service. Even WhatsApp has no way to read a users messages. See More

Top Con

Very unsettling new service agreements

You will soon need to agree to a new service agreement from Facebook, otherwise lose the use of WhatsApp. The agreement opens a lot of doors for Facebook to your data. See More

Top Con

Hard data collection

A lot of telemetry is collected as part of what is called "meta-data" or "anonymous data". It is only anonymous as in knowing where you live, where you work, where were you last weekend, your sleeping habits, your most opened conversations, all your contact addresses and how they address you, and much more - but not knowing you personally. See More

Top Con

"from facebook"

Wickr claims that one million users have downloaded the app with no information on how many active users they have. But even if every person that has downloaded the app is an active user, the userbase is really small compared to apps like WhatsApp that boast about hundreds of millions of active users. See More

Wickr

Top Pro

Group messaging

Top Con

Small user base

Top Pro

Doesn't require a phone number

Unlike most, you can use your phone but you don't have to. You can register without giving anything and add contacts either via e-mail (only) or phone number. See More

Top Pro

Includes a basic photo editor

The editor allows cropping images, drawing and writing text on them as well as add decorations. See More

Top Pro

Messages have user-defined lifespan

Messages can have a lifespan between 3 seconds and 6 days. Received messages arrive locked. Once they are opened by the recipient, a timer starts counting down until the message is deleted. Of course, the recipient can still copy them or take a screenshot. See More

Top Pro

By default, doesn't allow taking screenshots

Wickr disables the screenshot functionality altogether when the app is open. However, there are ways to circumvent this, as if the user has a rooted phone and has installed apps to overide this block or if a screenshot is taken via some apps that project the screen to a PC. See More

Top Pro

Can find other users securely

Instead of using usernames, emails or phone numbers to find other users, Wickr uses hashes derived from phone numbers or email addresses (this applies to the find friends functionality only). Hashes are the result of a one-way cryptographic function, meaning it's purposefully difficult to reconstruct original data (phone numbers and email addresses in this case) from them. For Wickr, hashes are generated on the client's side so that no personal information is ever sent to the Wickr servers. The app finds people on your contact list that also use Wickr by comparing the hashes that get generated from contacts and comparing them to the hashes that are stored on Wickr servers. See More

Top Pro

Content shredder

Wickr has a feature that not only erases all messages, but also overwrites them with junk data. See More

Multiple people have reported not being able to receive the activation code required to register the app. See More

StealthChat

Top Con

Many people have difficulty registering the app

Top Pro

Can send self-destructing messages

Messages can be set to self-destruct after a set time. See More

Specs

Platforms:Android / iOS

The app claims to be the only communication app that encrypts data in transit, on disk and on screen. Encryption in transit is used to make sure no-one can listen in on your conversations even if the traffic is going through their servers, encryption on disk is used to make sure that even if someone gets ahold of your phone and is capable of extracting your messages from it they won't be able to read them and screen encryption is essentially a lock screen that sets in after a set amount of time used to make prevent "shoulder surfing".

Enormous, constantly updated stamp collection

Since many brands use stamps for promotional purposes, everything from movies to food brands to Taylor Swift have released stamp collections. See More

Top Con

Users have been concentrated in Japan

Of the 360+ million registered users, the top country is Japan (50 million). Thailand and Indonesia are 2nd and 3rd with 33 and 30 million, respectively, with very small market penetration in the US (10 million, 11th place). See More

In 2013, Snapchat was hacked. As a result phone numbers and usernames of 4.6 million users were published online. That happened after concerns were raised by a security firm weeks before that Snapchat dismissed. Other security concerns were pointed out to Snapchat throughout 2014 including ways that the service could be used for DDOS attacks and how their anti-robot measures can be circumvented. Snapchat has since implemented two-factor authentication. See More

Snapchat includes a Discover page (accessed by two swipes from the right side) where curated list of news and entertainment outlets can put up news from their sites. See More

Top Pro

Does not get in the way of what it's designed to do

Snapchat is first and foremost a way to share photos so the first thing that the app presents the user with is the camera enabled and ready to take photos. Once photos or videos are taken, it's possible to caption them or draw on them. See More

Ryan A Pritchard's Experience

The Signal Protocol is the best standard end-to-end encrypted messenger system today. Both WhatsApp and Facebook Messenger Secret Conversations uses it to encrypt messages. Go to the source and use it directly! See More

Top Pro

Free as in both free beer and freedom, not as in "The customer is the product"

Pay Nothing - The development team is supported by community donations and grants. There are no advertisements, and it doesn't cost anything to use. See More

Top Con

Servers hosted in the US

A security risk due to National Security letters, which require giving up data to the US state, and making it illegal to disclose that. See More

Top Con

If SMS/MMS imported, other apps can't read SMS

For those using Join, Pushbullet, or similar apps to send and receive SMS/MMS from web or desktop, putting your SMS in Signal somehow breaks this functionally. The dev is aware but plans to remedy the situation have not been named a priority. See More

DelightfulSamshinHalmoni's Experience

Good, but not really useful. UX/UI has many issues. Snowden, Green and other hype persons (Don't believe the hype). Also US only hosted servers. Overhyped. See More

Top Pro

Free and open source

Signal is free and open source software, enabling anyone to verify its security by auditing the code. It's the only private messenger that uses open source, peer-reviewed cryptographic protocols to keep your messages safe. See More

Top Con

Centralized architecture

Signal's server architecture has been partially decentralized since December 2013, when it was announced that the messaging protocol that is used in Signal had successfully been integrated into the Android-based open-source operating system CyanogenMod. As of CyanogenMod 11.0, the client logic is contained in a system app called WhisperPush. According to Open Whisper Systems, "the Cyanogen team runs their own Signal messaging server for WhisperPush clients, which federates with Open Whisper Systems' Signal server, so that both clients can exchange messages with each-other seamlessly". The WhisperPush source code is available under the GPLv3 license. In January 2016, however, the CyanogenMod team announced that they will be discontinuing WhisperPush on February 1, and recommended that its users switch to Signal. After this, Signal's server architecture will be entirely centralized. See More
