Lightning Catcher vs ThunderCam

A lightning flash lasts milliseconds — far too fast for the shutter button. Lightning Catcher turns the problem around: the camera runs continuously, keeps the last frames in memory, and when the sky lights up, it reaches back in time and saves the moment that already happened. HOW IT WORKS • Put your phone on a tripod and point it at the storm • Arm the trigger; it adapts automatically, or optionally set a fixed sensitivity on the live energy column • The app measures the brightness of every frame — a sudden jump means lightning • Frames from before, during and after the flash are saved, and the highest-contrast frame is marked as your Best Shot FEATURES • Auto calibration: the trigger threshold adapts to your sky and locks in after the first hits • Robust trigger mode for city light and busy scenes • Exposure control with true hardware EV where available • 5–15 frames per strike, saved in order • Gallery with best-shot filter, full-screen viewer, save & share • No account required FREE TO USE Every capture is available in full quality, with no in-app purchases, subscriptions, paywall, or feature lock. Storms don't wait. Be ready before the next one.

Point your iPhone at the storm — ThunderCam does the rest. The camera analyses every frame in real time and saves a photo series the instant lightning flashes. No timing, no reflexes, no luck — mount the phone, press start, and watch the sky. WHY THUNDERCAM • Real-time flash detection at up to 120 fps • A photo series around every strike — frames before and after the flash, so the bolt is on the picture, not just the glow • Storm mode: exposure adapts to day and night automatically, or set ISO and shutter manually • Tinder-style triage: swipe through the catches — right to keep, left to drop; keepers land in your photo library • Motion filter: nothing is saved while you're still adjusting the phone • Catch alert: a sound and a tap the moment a strike is saved • Screen dim mode for long night sessions YOUR DATA STAYS YOURS ThunderCam is fully offline.
