Mobogram is a special and unofficial version of the telegram. It works with telegram's API and it allows you to use their official proxies to send, receive and forward messages. It also works with internal MTProto Proxies.

It can show you when each of your contacts changes their profile picture, username, name, or phone number.

Mobogram can forward messages and media without quoting, with editing or adding captions to media by using the "advanced forward" feature.

It also can show you the changes in a special section.

You can hide a chat, group, or any chat of the person you want to use secretly and only visible it when needed.
