Alright, so this is what you need to do. When you download it, and the popupp says you have no apps available to open it, click "Other" or whatever it's called. then go to (PC) C:/ProgramFils(x86)/Steam/steamapps/common/SimplePlanes and click simpleplanes (Android) should be this: Storage / apps / jundroo / Simpleplanes / Simpleplanes data or something like that. I haven't really used mobile since 1.8, so I don't know if it's changed or not.
