Intervals: Auto Camera Timer

Observin

About this app

Intervals turns your Android phone into a hands-free intervalometer. Set it up once, tap your camera app, and it automatically triggers the shutter at your chosen interval — so you can walk away and let it shoot.

Perfect for astrophotography, long exposure stacking, time-lapses, product photography, or any shoot where pressing the shutter manually every few seconds isn't practical.

How it works
- A floating timer window appears over your camera app. Place the tap marker on your shutter button, set your interval and shot count, and hit Start. Intervals handles the rest.

Accessibility API disclosure: Intervals uses Android's AccessibilityService API for one feature only — automatically pressing your camera app's shutter button on the schedule you set, so you can capture long photo sequences hands-free. The service only acts while your floating timer is running over the camera app you chose; it does nothing at any other time or in any other app. It is configured without access to screen content — it cannot read your screen and does not collect, store, or share any personal or sensitive data. You can turn it off anytime in Android Settings > Accessibility.
