Pro-level putting.
On your phone.
Smashfitter films your stroke, reads the green, and coaches you through it — all on-device. No sensors, no tripods full of wires. Just your phone and the green.
Stroke analysis, green reads,
and a coach that knows your stroke.
Putting Stroke Analysis
Capture a single side-view video and get face angle, attack angle, tempo, ball RPM, and full putter path — automatically.
3D Green Reads
Scan any green into a detailed 3D surface, see the optimal line, and know your make probability — all from your phone camera.
AI Putting Coach
An AI coach reviews your actual strokes and answers your questions with context from the session you just finished.
Watch Mode
Prop up your phone and putt. Motion-triggered capture auto-records every stroke — no tapping between reps.
The first putting lab that fits in your pocket.
Smashfitter combines three things no other golf app puts in one place: detailed stroke analysis from a single video, 3D green reading, and an AI coach that actually sees what you just did.
We built it because the pros who know putting — the stroke coaches, the green-reading obsessives, the fitters — have been locked behind expensive launch monitors and weekend sessions. That knowledge belongs on every green, every evening after work. So we put it on your phone.
Runs On Your Phone
No CloudStroke analysis happens right on your device. Your video never leaves your phone — fast, private, and works without signal.
