Pick a real, named beach and fall asleep to it.
Most sleep apps give you "ocean waves". Tidesong gives you Chesil Beach, where every wave drags a few thousand graded pebbles back down the bank. Or Hanauma Bay, a flooded volcanic crater where the reef breaks a long way out. Or Reynisfjara, black basalt sand and the open North Atlantic.
Forty coastlines, each with its own sound: gentle lapping, rolling surf, heavy surf, pebble and stone, reef and lagoon, wild coast, and ice on black sand.
A fade-out timer from ten minutes to twelve hours. The sound doesn't stop, it recedes — so nothing wakes you by ending.
No alarm tone. Over the last ten minutes the swell builds — sets arrive more often, closer in — and then the birds that actually live on that coast. Kelp gulls at Camps Bay. Kittiwakes in Iceland.
Every beach shows its own local clock. It's 4am in Bondi while you're going to bed in California, and Tidesong says so.
A new beach unlocks free every week, plus one full night. Everything open is $29.99 a year, $4.99 a month, or $59.99 once and never again.
