The app is pretty good. The algorithms are correct for what I’ve seen. I also like how it has a timer feature to practice algorithms. However the amount of algorithms is pretty limited. When it comes to the 3x3 it only has algorithms for the CFOP method, nothing for other methods like the roux method or zz method. And even then it only explains OLL and PLL for CFOP, nothing about the white cross or F2L and when it comes to the cubes it only goes up to 4x4. Nothing past that. Still, it’s a pretty good app if you need help learning or need a refresher.

This could be a good app if the developer looked at the app and just went through each step. The algs shown for 3x3 PLL, for example the Rb, is missing a couple of steps to actually solve the case. Each of the 3 algs for that case have missing steps. I looked at another PLL and you can only see the first line of the alg, the rest of it is cut off and you can only see the very top of those notations. If the developer had opened each screen and went through it, they would have instantly seen these issues.Hopefully the developer fixes this so that it can become a useful app.
