Telegram App Interface
Of all the apps we’ve seen Telegram is certainly one we would describe as messaging first & old school.
In the past two years, most messaging apps have adopted using tabs across the top or buttons across the bottom to facilitate navigation between the apps most meaningful screens.
The entire experience is centered around messaging, and therefore there is only one central interface, the messages panel.
All the other buttons are for initiating a new channel, group or start a call. Telegram really is a messaging app for people who message.
Telegram Channels :
This is how you create a new channel on Telegram
Telegram channels are a way of broadcasting information to a very large audience inside a messaging app.
Channels are easy to set up, all you’ll need is a name, a description and an image. Channels can be public or private.
Public channels can be searched for and found by anyone on Telegram while users will need a link to join private channels or be invited.
In the Telegram interface channels are available in the messaging interface in the same way as any other contact.
When one of your channels posts some new content it will bring that channel to the top of your messages list just as if your friend were to message you.
The most amazing part about channels though is that there is no user limit, there is an unlimited number of people in any given channel and to add to that channels are absolutely free.
