Anglage turns a phone into a watch timegrapher. Rest a mechanical watch against the microphone and watch its rate, beat error, and amplitude appear in real time.
Rate, beat error, and amplitude, updating live as your watch ticks.
A guided routine checks dial up, dial down, and all four crown positions, then compares the rate across each one.
Track rate over time, add notes, and keep every reading organized by watch. Backed up to the cloud.
A magnetized watch runs fast, and regulating it will not fix it. Hold the watch against your phone, once each way up, and Anglage reads the phone's compass sensor to tell a magnetized movement from plain steel.
