### *---- "Don’t download!"
First of all I can’t even open that app at all. It doesn’t even deserve a star. I tried using it on WiFi or just my data maybe that was causing it. Nope didn’t work either way. I tried shutting my phone off completely then turning it back on and that didn’t work either. Idk if it’s just my phone but don’t download it.
