Testers needed for Mongolian writing app

I am almost done with an Android app to send messages in traditional Mongolian. It is primarily intended for sending messages on WeChat, but it should work with anything that can share images. I want to know if the app crashes, what phone models and Android versions it works on, what is confusing, and what other features would be nice. If you would like to help with this then please send me an email. If you don’t have my email you can contact me here.
