Ranked in these QuestionsQuestion Ranking
Pro Strong encryption
Uses Curve25519, AES-256, and HMAC-SHA256. The security of these algorithms has been tested over many years of use in hundreds of different applications. Messages sent via TextSecure are end-to-end encrypted, which means that they can only be read by your intended recipients. We make it easy for you to verify that you are communicating with the right people and that no MITM attack has occurred. The keys that are used to encrypt your messages are stored on your device alone, and they are protected by an additional layer of encryption if you have a passphrase enabled.
Pro Passed EFF's security review
To pass EFF's security review TextSecure had to encrypt data in transit, the encryption had to be end-to-end, the app needed to provide forward secrecy, app's source code has to be open to independent review, users have to be able to verify contact's identities even with the service provider compromised, app's cryptographic design has to be well documented and app's source code has to have been audited in the last 12 months.
Pro Free and open source
TextSecure is free and open source, enabling anyone to verify its security by auditing the code. TextSecure is the only private messenger that uses open source peer-reviewed cryptographic protocols to keep your messages safe.
Pro Web and mobile (iOS, Android) versions available
Pro Supports text, voice, video
Integrates with Jitsi for multi-party video chats
Pro Uses Matrix, the open communications protocol
Pro Very good and simple interface
Riot has a very simple interface, adding the ability for more unexperienced PC-Users to use it.
Pro Widgets support
Want to watch that flick at YouTube and discuss it at the same time? Have Grafana graphs stacked above your DevOps team chat? Collaboratively edit Google Docs and chat over without switching applications? This is possible with Riot.
Pro Bridges to other networks
You're not confined within Riot's or even Matrix garden, and you don't have to make users of other networks switch to Matrix.
Con No data messaging
TextSecure can send SMS and MMS messages only. It can't send data messages.
Con Not available on tablets
TextSecure is currently not compatible with tablets. Support for tablets is promised in the future.
Con Still in active yet early development
There is clearly a User Experience issue esp. in web version which the developers are aware of and are working hard to improve. They've got the concept concrete, so UX won't be an issue in no time. Most often used parts are functional, but some are yet not.
The success of riot depends on how fast the development is, or it'll get outdated too quickly as developers of Signal and Telegram have predicted.
