Telegram Messenger is an open-source and secure and super fast messenger app that is completely open-source except design! Telegram won the Google Material Design Award of 2015. The app design is clean, usable and pixel perfect. You can't find any kind of Telegram UI kit or design language documentation on the web. So I decided to build an unofficial UI kit for Telegram dark mode for the Android platform. When I was building it up, I decided to add a conceptual online shopping feature. This Sketch file includes responsive symbolized layers and a complete prototype of the concept. This is the best resource for beginners. Feel free to use it as you wish. If you find it helpful, please let me know so that I can provide updates.
