Problem with playing

I have been have a problem with the Minecraft Pocket Edition for Android. At random times while I am playing, the game will untimely crash. It happens every time and I was wondering if I can get a modified version of pocket edition for Windows 10, if possible. I have bought minecraft for $30 already on a different device and $7 on mobile, it would be difficult to afford the actual Windows 10 version and spending a lot to get things to work.
