The Grid: GO
Go, baduk, weiqi: learn to see
Only for iPhone

iPhone
An opponent that plays at your strength, not at its best. It adjusts to how you actually play, and afterwards shows you the one move that mattered. Offline, no ads.
Every Go app runs an engine built to win. The Grid: GO™ runs an
opponent built to be worth playing.
If you get ahead, it does not resign. You play the game out and you
win it on the board, which is the only way that winning means anything.
AN OPPONENT AT YOUR LEVEL
Difficulty is not a slider, and not an engine crippled by cutting its
thinking time. The opponent plays at a set rank, using a network
trained on how people of each rank actually play. A weakened engine
makes alien blunders. This one makes human ones.
It moves that rank between games from how your games go - never in the
middle of one - and it keeps a separate rank for 9x9, 13x13 and 19x19.
Tell it your rank if you like and a new player starts gentler; from
there it follows how you actually play.
Playing the engine is a switch in Settings. Leave it off and the app is
a board for two people.
THREE MOMENTS, NOT FORTY
The engine can find every mistake you made. Showing you all of them
teaches nothing and is miserable to read.
After a game, the review picks out at most three moves, the ones that
cost the most, and shows you each one: the board as you saw it, where
you played, where the engine would have played, and an estimate of the
points it cost. A game with no such moment is told so, in those words.
If the analysis could not finish, the review says that instead of
guessing.
THE SCORE, SHOWN WORKING
When a game ends the score is not a verdict handed down. Every count -
stones, territory, komi, the points that belong to no one - is on the
screen, and it adds up to the result in front of you.
REAL EQUIPMENT
A kaya board with vertical grain and a satin finish. Double convex
stones with the proportions of real shell and slate, the black carrying
a restrained mineral cast that shows only in reflected light. No two
stones are drawn alike. A wooden clack when a stone lands, paired with
a haptic.
Pinch the board to zoom in and place a stone precisely on 19x19, where
the points are smaller than a fingertip, then pinch out to see the
whole board again. If you want, a setting asks you to confirm each
stone before it lands.
ECHOES
A small set of cards about Go's past, each built on one real object:
a painting, a print, a photograph, a board, a stone. Every picture
comes from a museum or library that released it openly, and every card
says where it came from. Tap a picture to see it full screen. Echoes
opens from the small mark beside Undo and Pass, only when you ask; it
never interrupts a game.
WHAT IS NOT IN HERE
No ads. No subscription. No in-app purchases. No currency, no streaks,
no daily login bonus, nothing engineered to pull you back. You bought
the app, so you have the app.
No account, no analytics and no network connection. The engine runs on
your device, so it works on a plane.

9x9, 13x13 and 19x19 boards

What's New
A head start, when you need one.
If you are at the easiest setting and still losing, Progress now offers to put stones on the board before the first move. They follow your results: a loss adds one, a win takes one away. No rank is attached to it.
Progress, rebuilt. It opens on a real position from one of your own games, showing the move you played and the move that was better, instead of general advice.
Three new pictures in Echoes, bringing the set to twelve.
Also in this version:
Games on 19×19 can be ended by passing
Delete many games at once from the Games list
The Games list and the board are faster, noticeably so on 19×19
Hints always say something, and no longer sit over the board
The review no longer points at a move you are not allowed to play
VoiceOver can open an Echoes picture and read its description
The review and the header hold up at the largest text size
