The Telegram Messenger app has just been updated to work on even more devices with the inclusion of official support for Android 5.0 Lollipop and documents multi-selection. The application was great, and the new update brought helpful improvements.
Telegram is a wonderful app designed by Indians, it's a messaging app with a focus on speed and security. As nice as WhatsApp, but with more features, such as Secret Chat for example. Moreover, Telegram has a tablet app, and Windows and Mac OS X clients. Android 5 and Material Design are supported. The most important thing is its performance; it fast, extremely stable and even works on slow 2G connections.
This application makes life easier, much better than WhatsApp which still has the same style UI for over 4 years. It is nice and easy to use and lot more features then WhatsApp like send more length video then WhatsApp or send pdf file and many others. The interface is really slick and fast, and the app is updated all the time. The corresponding apps on the web, Mac and Windows are awesome as well. It's what WhatsApp should be like.
It also very convenient, with just one registered mobile on Telegram you can use this application on cross mobile device like Samsung Note 3, iPad, Macbook pro, iPod and more.
