Real thunderstorms, rain, and ocean ambience — recorded to loop seamlessly, so the sound never breaks and never wakes you. ThunderSleep does one thing properly: it plays a beautiful soundscape and gets out of the way. No account. No sign-up. Nothing sent anywhere. 18 SOUNDSCAPES Storms rolling across mountain peaks, rain over open fields, thunder off a beach shoreline, a midnight storm in full voice, and soft ambient tones for meditation — across four categories: Thunder, Rain, Ocean, and Meditation. A SLEEP TIMER THAT FADES Choose anything from 15 minutes to All Night. When the time is up the sound fades out gently instead of cutting to silence, so it never jolts you awake. BUILT FOR THE DARK • Lock-screen playback controls with full artwork • A Live Activity on the Lock Screen and Dynamic Island — play, pause, skip, and the timer countdown, without unlocking • Keeps playing in the background, and the timer keeps running even if you close the app • Bedtime and wake-up reminders • Favorites, so tonight's sound is one tap away • Last night's rest from Apple Health, right on the timer screen • A design made for a dark room: deep blacks, soft glass, and gentle motion COMPLETELY FREE All 18 soundscapes, every timer up to All Night, the gentle 2-minute fade-out and the thunder wake-up sound are free for everyone. ThunderSleep is supported by ads, with no purchases and no subscriptions. PRIVACY ThunderSleep runs entirely on your device. There is no account, no backend, and no sync. Sleep data read from Apple Health never leaves your iPhone. — Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://racyinfotech.com/thundersleep/privacy.html
