How TrustPutt works
Hardware, software, and science — working together so you can focus on your game.
Clip the BLE sensor
The TrustPutt sensor clips onto any standard putter grip in seconds. It uses Bluetooth Low Energy (BLE) to communicate with your iPhone with sub-10ms latency.
The sensor contains a 6-axis IMU (accelerometer + gyroscope) that captures putter face angle, speed, and stroke path at 200Hz.
Pair with the iOS app
Open the TrustPutt app and tap Connect. The app discovers and pairs with your sensor in under 3 seconds. After the first pair, it reconnects automatically.
The app uses CoreBluetooth on iOS. Pairing data is stored securely in the device keychain.
Put and get instant feedback
Every putt is analysed in real time. The app shows face angle at impact, stroke path, and tempo — so you know exactly what happened before you walk to the next ball.
Analysis runs on-device with no internet required. Data is synced to our servers when you have a connection.
Review your session
After your session, view a full breakdown: putts holed, average accuracy, distance control, and trend over time.
Session data is stored in our backend and is accessible from both the iOS app and your dashboard at trustputt.com.
