Ratings and reviews

Recurring subscription fees bleed users dry ad infinitum, without an option to purchase the app once and for all. With superior competitor products being available that can be bought instead of rented, this milkingware has been replaced with three better alternatives, at a lower cost than what this programmer charges in a single year. Being able to play against a strong AI/bot is the entire point of using software, so it should be integrated in the local installation and not require Internet.

Purchased the game only to find out the full game requires a suscription as well.

If you are even remotely interested in Go/Baduk, then this is the app to go to. It has Capture go, very capable ai opponents on very affordable pricing, a really decent tsumego collection AND a great tsumego widget and now has added game analysis by ai! I am beyond impressed!
