Flash detection
A rolling brightness baseline helps identify sudden visual flashes that may be lightning.
StormSnapLightning photography for iPhone
Automatic lightning capture
Capture the strike. Keep the moment.
StormSnap watches the live camera preview for sudden flashes, identifies likely lightning directly on your iPhone, and gives you a replay of candidate frames so you can save the strongest shot.
On-device detection
No ads
No subscription
Purpose-built
A camera workflow made for lightning.
StormSnap focuses on the difficult part of storm photography: being ready during the fraction of a second when the sky lights up.
Strike Replay
Review candidate frames after a detected flash and choose the image that best captures the strike.
Focus target
Tap the storm area to guide focus and keep the camera aimed where lightning is most likely to appear.
Night-friendly design
A dark, high-contrast interface keeps controls readable without overpowering the live preview.
High-quality saving
Save selected captures directly to Apple Photos after granting the required permission.
Efficient monitoring
A battery-conscious option can reduce processing demands during longer capture sessions.
How it works
Prepare once, then watch the sky.
Set your iPhone on a stable support, point it toward the active part of the storm, choose a sensitivity level, and let StormSnap monitor the scene.
