Ninesmith - Sudoku
A Sudoku app with a coach who actually notices you
Every Sudoku app treats you like a vending machine spits out puzzles, doesn't know you exist, guilt-trips you the moment you miss a day. Ninesmith has a coach character, the Smith, who actually watches how you play and reflects it back in plain language never shames a broken streak. Free tier includes full classic + daily play and a pattern trainer that teaches real solving techniques (X-Wings, swordfish), not just hints. No ads, calm themes, built local-first with no backend.
Hey PH 👋 I’m a solo teenage dev. I built Ninesmith over the last 9 months of late nights and weekends.
Sudoku is my go-to way to zone out, but every existing app feels like a cold puzzle vending machine: zero personality, zero awareness of your style, and endless guilt-trips the second you break a streak.
I wanted something different, so I built Ninesmith. It features "The Smith"— an coach that tracks how you actually solve and reflects it back to you (“Third day running you cracked a Hard puzzle before 9 AM”). No shame, no pushy streaks, just insights into your game.
What’s inside (Free Forever):
Full classic play + daily challenges (zero ads)
A dedicated pattern trainer that teaches real solving techniques
Built local-first with React Native/Expo (no backend required)
Would love your feedback does the Smith concept land well, or does it feel gimmicky from the outside? AMA about the tech stack or design!
