GroupMe vs Telegram

GroupMe has a built in function to read receipts.

GroupMe has an excellent web client that can be used to send and receive messages and manage groups from the desktop.

Allows sending messages from web services via IFTTT.

It's possible to add location and time with reminders directly in the GroupMe app.

GroupMe has settings that allow muting a single group or turn off all GroupMe notifications from within the app.

GroupMe can set up a custom phone number which allows people without the App to send and receive messages. This makes it easy to add anyone to messaging.

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

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.

The application is available free of cost.

Videos, gifs, images, geolocation, and documents.

Very customizable with a lot of clean looking options.

You can set up an additional password to your account, which can be reset by your email. You don't have to use an email if you do not want to. If you lose access to your email or forget your password, you will be able to reset it via text message if your account is over seven days old and will receive it within a week (in case you recover anything before then).

Broadcasting channels suitable for announcing things.

In Supergroups, anyone along with admins can delete their messages from all sides. A message can be pinned to the top. All of the user's messages can be deleted by an administrator, and they can be banned and reported as well. Supergroups can have a public link (outside of Asia, due to high spam volumes), which is also a username.

Telegram uses an open source MTProto encryption protocol that provides complete end-to-end encryption for secret chats. To show off their confidence in the protocol the company behind Telegram has organized $200,000 and $300,000 challenges to break the encryption. So far there have been no winners.

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.

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.

Uses the latest GPL audio codecs, such as Opus, an adaptative high-quality codec that supersedes AAC at any bitrate.

The desktop app has a built in setting to scale the UI of the app up to 200% which allows for those with 4k monitors/screens to use the app without scaling issues.

Although it's volunteer based, but still pretty top-notch if available, which it tends to be.

You can post voice and video messages if you are too lazy to write text messages.

You can ping people to get their attention by @mentioning them.

You can write messages to yourself. You can write some notes, add links, and see everything across all your devices.

There are native desktop, mobile and web client apps, that are optimized for speed and are light on memory usage.

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