App works great, after figuring out how to use it

The app works perfectly. keep in mind, you CAN play with japanese rules against 20 kyu human-like katago model, however you can only do this on 19x19 board after first purchasing the katago model, and THEN the human like model. the app is great and the developer is VERY responsive and helpful.

Needs to get better

This app is good if you are going to play against AI or start a study game from scratch. You cannot set up a position. When you import a game it always starts with the wrong player and doesn’t have an option to change player’s turn. These features need to be installed soon because they are very fundamental. Image recognition is also a nice-to-have feature. Now I use another app to capture a board image, then I export the sgf to another app to set the correct player’s turn and only after then I can start to study with this app.

A good start

I’ve been waiting for this since the Leela zero project emerged (still waiting for the chess version, but that’s ok). Some improvements could be used: 1. The user interface in general can be improved. Take a hint from some of the other popular go apps. 2. If you leave the app (not necessarily closing it even) the game wipes and for some reason is copied to your clipboard so you can paste it back and resume... clearly users shouldn’t have to do that. 3. It’s up to the user to load non-default network weights. It’d be nice to have those already loaded. You could make it such that there’s every difficulty level from random to pro by loading specific weights. Could track users progress as well, as is done in crazy stone app. 4. There’s a dynamic Komi branch of Leela zero. Could be used for maintaining the AI’s strength and still allowing high handicap games. That is all. Thank you.
