TG Timer is a mechanical watch timing application for iPhone. It records audio from your device microphone to measure the rate, beat error, and amplitude of a watch movement.
We collect no data.
TG Timer does not collect, store, transmit, or share any personal information or audio recordings. All processing happens entirely on your device.
TG Timer requires microphone access to receive audio from a piezo contact microphone connected via USB-C adapter. Audio is processed locally in real time and is never saved to disk, uploaded, or transmitted anywhere.
The only data stored locally on your device is your watchmaker name, saved in the app’s preferences so you don’t have to re-enter it each session. This information never leaves your device.
TG Timer does not use any third-party analytics, advertising SDKs, or tracking libraries.
