My new favorite go problems app (UPDATE)

I love solving go problems on my iPhone (it’s almost as if it was designed for that :-)) and up until a few days ago, my go-to app was the GoProblems app (which is great, and you should all get it). Then I discovered Tsumego Pro, and I think I like it even more. The only negative is that the black stones are simple black circles; a little shading could make it look a lot better (devs?). Other than that, everything has been done beautifully. The daily problems are a nice touch, but the real killer feature is the progress mode, which assigns you a rating based on how many problems you’ve solved successfully. This is a great motivator and a way to prevent sloppy playing. Also, there are no time limits, so you can take your time solving problems. All in all, this is a very well-done app, and well worth your money if you are a Go fan.

UPDATE: I’m docking one star for two reasons. First off, the problem difficulties are all over the map, as others have mentioned. The beginner pack (for instance) has lots of problems that are way beyond beginner level, as well as some easy ones. Second, there are two many cases where the move sequence given is just wrong. Sometimes a move listed as wrong turns out to be perfectly OK, and sometimes the supposedly optimal sequence isn’t. There is no question that this app has a great interface, but the problems need to be vetted better.
