I’m really enjoying the Tile Tutor app. I’m brand new to Mah Jongg and it’s very helpful being able to enter your tiles and see the best possible hand options.One suggestion I have would make it even easier to use. On the Best Hand Results page, you can already press and hold tiles you plan to discard. But in the suggested hands, the tiles you already have are bright while the tiles you still need are dimmed. It would be great if users could also press and hold the dimmed tiles to quickly add them when they draw them. I think that would make tracking possible hands much faster and more convenient during play.

Finally some lessons that clearly could help beginners. How to get your hand and the tutor on screen at the same time
