It has a great idea, but in reality it doesnt work. The screenshots is constantly not loading and the one time it loaded, it read everything as water or dark orbs. The alternative for manual input is poorly implemented as well, because if you double-click home button - to check the original board - when resuming to this solver, it will try to load the image again, forcing you to input everything manually again. In this manner, it is even worst than using any web solver.
