Review momentum
ⓘ How we measure thisNew ratings a week
–
Apple's rating count fell over the last 4 weeks: it removed more ratings than came in (spam clean-ups, deleted accounts), so the pace can't be read right now
Lifetime rating
3.0★
recent stars not readable yet: new ratings are a tiny share of the total
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Go Lab: AI Baduk KataGo Engine
KataGo in the palm of your hand. A Go app for playing seriously and analyzing seriously.
Powered by KataGo (b18c384nbt). HumanSL that recreates human playing styles, blunder analysis reports, AI commentary prompt generation, board photo import, and OGS play. Supports 9×9, 13×13 and 19×19, with every feature and model included at no extra cost.
■ KataGo Models: 3 Included
• b18c384nbt: A powerful model that runs on CoreML. It truly shines in 19×19 play and analysis
• b6c96: A compact model bundled with the app. Light and fast
• HumanSL: A model trained on human game records for a human playing style. Play opponents close to your level, from 20 kyu to 9 dan, and switch between modern and classic (pre-AlphaGo) styles
■ Real-Time Analysis
• Candidate moves: Shows KataGo’s top 10 moves with win rate and score estimates
• Win rate graph: Updates after every move
• Territory estimate: Shows black and white territory on the board (can be toggled on/off)
• Thinking time visualization: Highlights long thinks in red and yellow
■ Post-Game Review
• Blunder analysis report: Lists the moves that cost you the game. Each position shows the AI’s recommended move, a variation diagram, and the difference in points and win rate. Copy or share it as an image
• Review mode: Play out variations from any position to create branches. Add PV (principal variation) lines and compare evaluations in the review tree
• AI commentary prompt generation: Ports the concept detection layer of Kifu-Sensei (MIT). Automatically extracts facts such as cuts, ladders, and group stability from your game record and builds a high-quality prompt that lets an AI give accurate commentary. Just paste it into the AI of your choice to get a written explanation of why a move was a mistake, something KataGo’s numbers alone cannot tell you

• Tsumego mode: 347 problems from the Xuanxuan Qijing
■ Focus Mode
• Zen mode: Quietly fades out all UI except the board. Switch it on with the Zen button at the top right of the board
