Clunky implementation, but useful
First the good: I wanted a little quiz game that gives you a tile with an element, and asks you to drag it to its spot on the Table. This is the ONLY one I found that does that. Hurrah! Now the bad: why on earth did the developer choose to present the Periodic Table in portrait orientation (I’m on an iPad) instead of its natural aspect for its shape, which is landscape? This forces you to scroll side to side to see the whole thing. Worse, when it starts out, it presents an element tile, and the instinct is to try to slide it to its proper place (exactly as the instruction says!). But it won’t move! Took me awhile to realize I had to DISMISS the tile, and then POINT to its spot on the table. Very non intuitive. Also, when I went into Settings, the app hung up and I had to force quit. (I’m on a 9th generation iPad, if it helps debug.)
