I love telegram because of it’s groups function. We can add unlimited participants in group which is unlike other apps. The user interface is very good and we get all the functions like all other apps.
The app is not so heavy and works very smoothly and you can join your category group. I also like the telegram bot for groups which helps you to secure your group automatically and block or put restrictions on people who spam or send unusual message on your respective group. So I would recommend this app to everyone.
