Rain sounds for sleep and thunderstorms, softer than white noise, calm with tinnitus. Sleep timer, offline, no ads. Seven full nights free, then 15 min a night, pay once. Rain sounds for sleep that play all night, free in full for your first seven nights. No subscription, no ads, completely offline. Tropf is a sleep aid built around rain: 105 hand-picked rain mixes made from 128 recordings, each one built as a seamless loop. No click at the seam, no stop after an hour, no restart at three in the morning. Rain that runs until you sleep, and keeps going after. THIS SIMPLE 1. Tap a soundscape and the rain starts 2. Set a sleep timer, or just let it run 3. Put the phone down and the screen goes dark SLEEP SOUNDS THAT LAST THE WHOLE NIGHT - Plays with the screen locked, through AirPods, headphones or a Bluetooth speaker - Seamless loops with long crossfades, built for sleep, not for background music - Three or four sounds in every mix: rain on a window with drops on the sill, storm rain with distant thunder, a summer night with crickets - With or without thunder: thunder is a layer you add or take away - Sleep timer: 15 minutes, 30 minutes, 1 hour, 2 hours, until sunrise or until you stop it. The rain fades out over a minute, it is never cut off - Sound filter: bass, mids, brightness. Darker for sleep, more open for work. Six presets in plain words instead of decibels - Your own mix: add sounds, set each one louder or softer, far or close, stack up to six, save it with the heart - A call pauses the rain, and afterward it picks up where it was - English, German, Spanish, French or Portuguese, switchable any time in Settings. The controls stay on the lock screen NINE SOUNDSCAPES: RAIN, THUNDERSTORMS, SEA AND FOREST Gentle rain: drizzle, spring rain, rain in the garden, mist Heavy rain: downpour, monsoon, cloudburst, night rain on the roof Thunderstorms: distant thunder, a storm close by, hail, a summer thunderstorm Rain at night: crickets, frogs, an owl, wind around the house Rain in the city: street, café, train, wet asphalt Rain on the window: drops on the glass, skylight, backyard, library, train window Rain on the roof: tiles, tin, attic, fireplace Forest and meadow: leaf canopy, brook, meadow, tropics, nature sounds for relaxing Sea and river: ocean waves, surf, river, mountain stream, lake WHO TROPF IS BUILT FOR - Falling asleep when your head will not settle - Sleeping through street noise, neighbors or snoring - Shift work and sleeping in the daytime - Focus at the office and at home, studying - Winding down in the evening - A softer alternative to white noise, which many people find too harsh. Rain masks noise just as well and sounds like outdoors - Tinnitus: a quiet background sound that takes attention away from the ringing PRICE: SEVEN NIGHTS FREE, THEN PAY ONCE Your first seven nights are completely free, each one all night long, every soundscape, every feature. After that Tropf plays 15 minutes a night for free. Pay once and nothing changes: the rain stays until you stop it, forever. No subscription, no subscription trap, no hidden costs. The purchase works on every device signed in with the same Apple ID, and Restore Purchases is in Settings. PRIVACY No sign-up, no ads, no tracking across other apps. Anonymous usage statistics (PostHog) so we can see which soundscapes help. Every recording is inside the app, no internet needed, even in airplane mode. Rain sounds, sleep sounds, a gentler kind of white noise, made with care in Norway for real nights. Tropf: one drop after another, until you sleep. Questions?
