I have been using the telegram app for more than 2 years and I genuinely loved this app.
Display: -The app has blue paper aeroplane logo and a white and black interface which look really awesome.
Ease to use: - It is veryeasy to use and any age group people can use it freely without any restrictions.In my opinion it is more easy to use as compared to Whatsapp.
Security: -In my opinion telegram is more secure than whatsapp.It comes with end to end encryption.The key point is that there is no complaint regarding to security of telegram.
Cloud Storage: - Telegram provide more cloud storage as compared to whatsapp and it provides very easy handling.
Overall in my opinion it is very awesome app as compared to other similar apps like whatsapp, hike, etc.
So anyone can go through telegram instead of other apps and they will never get disappointed.
