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.

Thank you for the feedback. Hactar go has multiple uses: problems, SGF editing, pattern search etc. Only use of the server-based strong go bot requires subscription. All other features are included in the application price. If you do not need a strong bot, there is no reason to subscribe.

Easily the best Go App I've used Nice crisp clean graphics. Beginners puzzles that are really for beginners with a hint of what the player should be aiming for . Invite for optional feedback by email . Nice animation . All in all an accomplished app.

Great but in problem mode it really needs a way to replay my solution (fwd) step by step. As a beginner sometimes i solve something by intuition and I'm not entirely sure why. To lock in the learning its helpful to see a replay!
