How the TestaDigi app automates your activity tracking just by unlocking your phone

The traditional "Dead Man's Switch" requires you to periodically log into a platform and press a button to confirm that you are okay. While effective, it can be tedious and it is easy to forget. To solve this, at TestaDigi we have developed a revolutionary mobile app that automates this process in the most natural way possible: by unlocking your phone.

How does the magic behind the app work?

Our Android app features an optimized background service that strictly respects your battery and privacy. When you activate the "Biometric Unlock" feature, the app starts listening for system events.

The moment you pick up your phone and unlock it (whether with your fingerprint, facial recognition, PIN, or pattern), the Android system emits a signal. TestaDigi captures this signal and silently connects to our servers using a secure cryptographic token that identifies your account, automatically renewing your inactivity timer.

Privacy and Security guaranteed

We do not track which apps you use, nor do we read your messages, nor consume unnecessary data. The only piece of data we send to our servers is an encrypted "I am here!" every time you use your phone. This way, as long as you keep using your phone in your daily life, your future messages and digital legacy will remain scheduled. If one day you stop unlocking your phone, the TestaDigi timer will simply run its course.
