What are the best messaging apps for iOS?

Unlike many other apps, signal provides not only text messaging but also live encrypted voice calling. See More

Top Pro

Encrypted voice calling

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

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

Code being used in Whatsapp and other parties undermines trust

It's unlikely FB would add encryption it does not have access to. See More

Top Pro

Supports phone calls

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

DelightfulSamshinHalmoni's Experience

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

Specs

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

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

Top Pro

Straightforward interface

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

ifygal's Experience

A lovely app to use See More

Top Pro

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

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

Anthony's Experience

Excellent app to use. 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

Top Con

Proprietary

Not open source. See More

Anil Atluri's Experience

I hate the proposed ads to appear. 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

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

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

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

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

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

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

Top Con

Doesn't support sending voice notes or video recordings

Top Pro

Group video support

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

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

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

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

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

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 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

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

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

Great UI

User interface of the application is clean, intuitive and easy to overview. 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

StealthChat

Top Pro

Can send self-destructing messages

Top Con

Code is not verified

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".

Top Con

Requires both ends to be online (if neither end is using a cloud-enabled device)

Messages are sent and received only when both ends are online, if neither end is using a cloud-enabled device. In this case, if you are online 9-17 and your recipient is online 18-3, messages will never be delivered. See More

Top Pro

Send SMS and make regular calls

Wickr

Top Pro

Includes a basic photo editor

Top Con

Small user base

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

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

Group messaging

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

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