Toach turns your iPhone into an AI tennis coach. Prop your phone on the fence and play — it detects every forehand, backhand & serve, measures swing speed, and gives shot-by-shot coaching. No wearables.
I'm building Toach because I got stuck.
I'm a 4.0-ish club player who hit a wall — I knew something was off with my forehand, but I couldn't see it, and a private coach every week wasn't realistic. Watching slow-mo of myself just left me guessing.
So we built the coach I wanted: prop your phone on the fence, hit some balls, and get told the one thing to fix — and exactly how to fix it.
What it does:
🎾 Free swing assessment — hit ~10 balls, no signup wall
📱 No wearables, no operator — just your phone on the fence, any angle
🧠 On-device AI finds your critical flaw per swing (forehand / backhand / serve) and gives a plain-English fix — not a wall of stats
💬 Coach Tina — ask "why?" and get a real answer, like texting a coach
📊 Technique Score so you can watch yourself actually improve session over session
What makes it different: most apps throw numbers at you (speed, spin, charts). Toach is built around one question — what should I fix on my next shot? The corrective cue, not the vanity metric.
It's early and I'd genuinely love your feedback. What stroke is your nemesis? Drop it below — I read every comment.
