My first app! Any advice?

☎ Ringo (MAKERphone) đŸ’» Games & Apps - Arduino/C/C++
#1

My daughter has just made her first app.

  1. It is very slow to start - is there a minimum library include option that makes it quicker to compile? (we are not using any functions except: drawing color and text, buttons)
  2. We are unable to get supprot for UTF8 (Swedish characters ÄÀö)
  3. We couldnt find “input” or similar command

Any other advice would be greatly appreciated!
