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. No account, no sign-up, no analytics, no ads — the App Store privacy label says "Data Not Collected" because there is nothing to collect. Photos go straight to your own photo library.
