I just tried to score my last game and it got it right, but there is strange problem - when I import picture from my gallery, it rotates picture 90 degrees counter clockwise. And sad thing is that I can't turn it to normal in app also. It doesn't change the score, but I would like to see table in correct position. Simple photo editing ability should be in this app (changing contrast, saturation, rotating and cropping). Especially when app is commercial.

I would say this application is probably more useful to a more experienced player or a frequent player since it does help analyze the next possible move in a given position and it also helps with calculating territories. I just wish the app has more features. Overall, it is a good app.

3* @ pres., because unclear FUNCTIONALITIES: transforming any Go board position into a diagram works sufficiently well even from very inclined viewpoints in shady light. UNCLEAR hereafter: 1. coordinates (1-19 & a-t) possible? 2. in X/Y resp. Y/X axes? 3. Capital coordinate letters? 4. WHERE is diagram stored post-SAVE?? 5. LOAD does nada after SAVE!!. 6. SGF export to eMail & ~readers by 'SHARE' 7. ANALYSIS: Crazy Stone does NOT cooperate; Tom (Go 3 dan EGF) Samsung S10, Android 12
