Sensor Mount / Oar Calibration

The app button is Sensor Mount / Oar Calibration. It includes a simple sensor mount-angle check plus the tools used to choose, edit, manage, share, and create oar calibrations.

Why calibration exists: all of the calibration tools are there to get an accurate Scale Factor. Scale Factor lets the app turn measured oar bend into realistic force, work, power, and power split values so rowers can compare their total effort between workouts, oars, and setups.

What calibration does not change: Scale Factor does not change force-curve shape, stroke length, ratio, catch miss, finish miss, max rotation speed, or any metric that does not use Scale Factor. A different Scale Factor changes the magnitude of force/work/power-style values, not the timing or shape of the stroke.

In-app tabs

The Sensor Mount / Oar Calibration screen has four in-app tabs. The first tab is only a mounting-angle check. The other three are used to select, edit, manage, share, or create oar calibrations.

App tab	Use it for
Mnt Ang check	Check whether the two sensors are mounted at a reasonable angle. This is separate from Scale Factor calibration.
Calib - sel/edit	Select the active calibration, edit dimensions or calibration values, scan an oar label, and save changes.
Calib - manage	Import, export, delete, select, label, and share saved calibrations.
Calib - create	Create a calibration from a known-weight bend test. Many rowers may never need this tab.
