This is for all the lightning lovers out there. Turn your room into a thunderstorm. Lightning plays immersive thunderstorm soundscapes and syncs the light to the thunder: the screen dims to black, then pulses and flashes with every rumble — and on the loudest strikes, fires the camera flash like real lightning. Set the storm's distance and the thunder trails the flash, just as it does in a real storm. Best experienced in a dark room, with the screen and camera flash exposed and the audio through speakers or headphones. Made to fall asleep to. A sleep timer gently fades the audio and light to black instead of cutting out, so it never jolts you awake. FREE • The Starter Storm, full flash + thunder experience • Storm distance (flash-to-thunder delay) • Sleep timer with a gentle fade-out LIGHTNING PRO — one-time purchase, yours forever • Every storm — all six soundscapes • Immersion modes — screen-only, soft ambient glow, and warm-to-cool lightning color • Haptic thunder — feel every strike • Storm control — strike intensity and an approaching-storm mode • Gapless playlists with seamless crossfade • A StandBy / Lock Screen storm clock widget • Longer overnight sleep timers • Save custom presets No accounts, no tracking, no ads. Everything runs on-device. Already bought the old Storm Expansion? Tap Restore, you're upgraded to Lightning Pro for free. Relax and unwind, Go ahead, Enjoy the Storm.
