The app works, for sure, but it'd be nice if there was a way to designate where the color would be. Also, it would be greatly appreciated if there was a way to see what I'm coloring, as my fingers (my thumb specifically) are quite large and block my view of what I'm doing. The eraser tool gets rid of mistakes I make handily, but again, a feature to allow me to see what's under my thumb without removing it would be greatly appreciated. Additionally, the app stutters and stammers whenever I try to move the image after beginning to recolor something. The problem is nonexistent beforehand, but afterwards, moving the image becomes quite the ordeal. Finally, there's no greyscale. Or at least none that I could find. I saw a color wheel advertised, but there's none to be found. Other than those, the app works well enough for what I need it for. Thank you for your time.
