Ranked in these QuestionsQuestion Ranking
Pro Includes filters
It's possible to change the look of images and videos via filters.
It's possible to send messages to multiple people at once. Either by setting up a group or by selecting a bunch of people individually. Groups can also be muted if they get too noisy.
Pro Messages self-destruct after they've been viewed
Once a message has been viewed, it gets deleted from Snapchat's servers. Thus, unless a person chooses to save the message manually (a notification will be sent if a user decides to take a screenshot), there will be no trace of it left. It enables a bit more consequence-free, in-the-moment kind of communication to occur.
Pro Generates a contact list
Once the account setup process is complete, Mirage generates a list of people from your contacts that you are most likely interested in sending messages via Mirage.
Pro Interface designed for getting things done quickly
Tap a contact to take a picture, tap and hold a contact to record video. Tapping the screen will allow you to add text to photos and videos just taken. Swiping the screen changes what camera is used. Swiping from the side allows sending text and voice messages. Voice messages are recorded the same way videos are by tapping and holding on a contact just from a different view.
Pro Uses Matrix, the open communications protocol
Pro Supports text, voice, video
Integrates with Jitsi for multi-party video chats
Pro Web and mobile (iOS, Android) versions available
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.
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 Very good and simple interface
Riot has a very simple interface, adding the ability for more unexperienced PC-Users to use it.
Messages get lost users have trouble getting their codes to log in and has trouble actually finding the users contacts.
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.
