KataGo in your phone
Two built-in KataGo neural network models, running on the Neural Engine first — same strength, less battery, and no network needed for play or analysis.
9, 13 and 19 lines, with handicap
Three board sizes and handicap settings so every level finds the right challenge. The AI can pass, and you can always take back a move.
Teaching-game commentary
Every move is graded by win-rate swing: good move, small loss, questionable, blunder. “Suggest next” marks the recommended move on the board — it never plays for you.
Influence map & score
One tap shows the influence map and the live score difference — whose territory is whose, and by how many points.
Records & review
Study famous games with variations, marks and comments. Import SGF, pull your games back from Tencent Go, and sync progress through your own iCloud.
Tuned for iPhone
Three power modes — low, normal, full. It steps down when your phone runs warm and recovers when it cools. Sounds follow the mute switch and never interrupt your music.

Ten-level AI ladder
From “Beginner” to “OneSolve”, each level plays with its own style: low levels miss defenses, high levels build double threes and hunt long wins — not one engine with a depth slider.
Real Renju rules
Switch freely between freestyle and Renju. Double-three, double-four and overline lose for Black — and every forbidden point is marked with a red cross right on the board.
Live win rate & hints
Ask for a hint or take back a move any time. The live win rate shows you exactly which move lost ground — and how much.
Auto-saved game library
Every game is saved automatically. Replay move by move, branch off from any position to try a different line, or ask “what’s best here?”
SGF import & export
Full SGF and coordinate-notation support. Bring in games from anywhere, replay them move by move, and take your own reviews with you.
LAN head-to-head
Same Wi-Fi, or one phone’s hotspot: one device hosts a room, the other joins. Traffic goes device to device — never through a server.
PAID FEATURE · AI COACH
It watches the board.
It coaches in plain words.
When you play in another app — or over a real board with a friend — it reads the position through screen recording, and on your turn tells you where to play with voice and picture-in-picture. It says “block the right end of your row of three” — not grid coordinates.
All recognition and calculation happens on your device. Nothing is ever uploaded.

PHILOSOPHY
Offline is a feature.
Neither app has sign-up, login, or any personal data collection — the engines run on your device.
Go syncs your records through your own iCloud, never through our servers — we don't have any.
