WatchOut silently takes a selfie every time you unlock your phone, building a beautiful visual diary of your day. And if someone enters the wrong PIN, the front camera fires instantly - no flash, no sound - and saves the intruder to a hidden, secure gallery.
A wrong PIN fires the front camera - no flash, no sound, no trace.
Every screen is built around a single idea - capture quietly, reveal beautifully. From the live diary timer to the silent intruder alert, this is how WatchOut feels in the hand.






Two apps in one: a private photo journal that captures your day automatically, and a silent guard that catches anyone trying to break into your phone.
Every unlock becomes a timestamped selfie. Browse your day as an effortless photo timeline.
Wrong PIN or pattern? The camera fires immediately and the shot goes straight to a hidden gallery.
Your personal diary and intruder captures live in entirely separate, clearly labelled galleries.
Lock WatchOut itself with a PIN or biometrics so nobody can browse your diary or delete evidence.
Fully localised in over fifteen languages so the app feels native wherever you are.
See how often the phone is unlocked, the busiest times, and a full log of every access attempt.
