This app is well, an okay app. There are a few things I have to say. First of all, idk if it’s just me or the app, because when I tried my 4x4, it ALMOST worked, but there was just this one cube, and I had to start over again. I tried it a second time, but it looked like nothing. But like I said, it’s either me or the app. I also tried to do my megaminx, but it said that there was a lighting and color error. I could’ve turned the megaminx wrong, but it always said that there was a lighting error. The last thing I have to say is that it can’t pick up colors as fast at you want it. When I tried to use my pyraminx, it didn’t pick up the colors, although you can clearly see it. Oh yeah, I don’t like that you have to watch ads or pay just to solve a Rubik’s cube. I wish there was unlimited puzzles. Overall, this is an okay app, and I recommend it to other people.
