Yamazo Stopwatch

A stopwatch for field time studies that runs on your phone, with or without a network. Enter your email address and we will send you a one-time link.

What we store

Your email address, your language, the time and version of your acceptance, and your optional newsletter choice. To limit abuse we also keep a keyed hash of your IP address, never the address itself.

Your measurements stay on your phone. They leave it only through the QR code that you show to Yamazo Studio.
