Why cant apps be EASY??

The app looks like it has good maps, then you have to do a whole process on the computer, which I did, which DID NOT WORK GOSH DARNIT. Why cant it just be an app that says "tap to download to minecraft" instead of when you click one, its a whole darn process!
It was so easy on my kindle, why not anymore?!? Dont buy it. I want my money back for this crumby rubbish.
