How it works
1Point at the storm
Mount the phone or hold it steady facing the sky. Press start — that's the whole setup.
2It catches the flash
The camera analyses every frame in real time and saves a photo series around each strike — automatically.
3Keep the best
Swipe through the catches: right to keep, left to drop. Keepers land in your photo library.
Built for storm nights
Storm mode
Exposure adapts to day and night by itself — or take full manual control: ISO, shutter, EV, sensitivity, pause.
Motion filter
While you're adjusting or carrying the phone, nothing is saved — no junk shots from a shaking camera.
Catch alert
A sound and a tap the instant a strike is saved — watch the sky, not the screen. Plus a screen-dim mode for long nights.
