BeatSleep: Sleep Tracker

BeatSleep does one thing. Your Apple Watch reads your heart, then vibrates on your wrist just under your own rate. Your pulse follows the vibration down, and you fall asleep. No sound, and nothing to watch. The screen exists only to prove it is working, and it fades away once you no longer need it. HOW A NIGHT GOES For the first 45 seconds nothing vibrates, while BeatSleep measures the rate you are actually resting at. Then the cadence anchors there and sheds four beats every ten minutes, staying just under your pulse: far enough to lead, close enough to be followed. If a noise wakes you, it stops pulling and re-anchors to your real heartbeat within a minute. Apple Watch gives an app only a handful of vibration patterns, and most carry a tone through the speaker. BeatSleep uses the one that does not, so the person beside you sleeps through your night. The night closes itself five minutes after your pulse has settled. A hard fifteen minutes, or the whole night, are yours to set instead. IN THE MORNING Health will tell you that you slept seven hours. BeatSleep will tell you that forty minutes of them were awake in eleven separate pieces, how long you took to fall asleep, and how far your pulse fell below your resting rate. It reads Apple Health, so there is something to show you on the very first morning. ON YOUR HOME SCREEN A widget that leads with the figure you choose: how long the descent took, the nights in a row, the lowest rate you held, or how closely your pulse followed the vibration. And every night is in Spotlight, so you can ask for one in your own words and open it. The index is built on your device and stays there. NOTHING LEAVES YOUR DEVICES No account. No server. No analytics, no advertising identifiers and no third-party SDKs. Your heart rate is read from HealthKit on the watch, the summary is computed there overnight, and it travels to your iPhone over Apple's encrypted device link. If you turn on iCloud sync, your nights go to your own private iCloud, in encrypted fields, never to us. You can export everything as a file, or erase it for good, at any time. BEATSLEEP PRO Free leads three nights in any seven days, and they are whole nights: the same descent, the same failsafe, the same morning summary. Pro lifts the count to every night, and adds your full history, every month behind you, the Thrum and Hush waveforms, a breath with your own four counts, iCloud sync, and the rest of the colors. BeatSleep Pro is €3.99 a month or €24.99 a year, billed to your Apple Account and renewing until you cancel, which you can do at any time in Settings.
