Ultrahuman Ring Sizer vs rotation+

Ultrahuman Ring Sizer is an app that lets you instantly find out your Ultrahuman Ring Size. All you need to do is click a picture of your hand with a standard sized card in the frame and our State-Of-The-Art Vision algorithm will calculate the perfect Ring size for you.

Rotation+ is a utility for capturing repeatable rotation and stability measurements with a connected motion sensor. Create a profile, select the movement types you want to measure, connect a supported sensor, and follow guided session prompts. The app records angle data, compares results with configurable targets, and saves sessions for later review. Use it when you need a simple tool for consistent setup, live sensor status, saved history, and exportable measurement records.
