How it works

Phone pointed at a storm detecting lightning

1Point at the storm

Mount the phone or hold it steady facing the sky. Press start — that's the whole setup.

Automatic capture of a lightning flash

2It catches the flash

The camera analyses every frame in real time and saves a photo series around each strike — automatically.

Reviewing captured lightning photos

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.
