Challegram, telegram contest winner


Today we bring you Challegram – another unofficial Telegram client. Challegram has won the Telegram Android Challenge – a contest where developers have the same task and try to achieve the best possible result. Contest is organized by the Telegram’s founder, Pavel Durov, in a Russian social network VK.


So, the other day we downloaded the application to test it some days before making the review and to keep testing different features. The truth is that we got pleasantly surprised because the app was very fast and smooth, the design is very minimalist and elegant. Therefore, the app first impression was positive.

When we test an unofficial telegram client, we especially like to check the different features offered by the official telegram in order to see how they approach it. Reply, share, channels, supergroups, settings… it has so many features if we consider that is an application still in development, because in fact, the contest has already finished. (we will give more info about the VK telegram contest). Rich animations, #hashtag search mode was awesome and liked the feature to play YouTube videos on the background!

Supergroups yes

Based on TDLib

As for technical specifications highlight an important fact: Challegram is based on TDLib (as all apps taking part in the contest), an experimental Telegram Database Library (Beta) ( It is a tech platform written in C ++ designed to increase the speed of Telegram and allow developers to easily make their own version. This library is developed by the creators of KPHP which is used for VK and Telegram server side.

TDLib has the potential of Telegram and the main difference is not having to deal with low-level things like encryption, transport layer and the local database. But use with cause: it’s in beta and there may be any sort of bugs.

In conclusion, we got an excellent impression of Challegram, which we wish all the best in the future.
