Sleep Map

Sleep well tonight and a piece of the world becomes yours. Sleep Map is a non-competitive sleep-habit app, played alone or with a small circle of friends. Pick your hometown, set the hours you mean to keep, and put the phone down at bedtime. Keep the night and, in the morning, you claim a place — the one next to ground you already hold, spreading outward from home a night at a time. A bad night just slows things down. It never takes anything back. Territory you have earned stays earned, always. There is no punishment here and nobody to lose to. Many places tell you something true about themselves before you go under. Not a travel brochure — one specific, surprising, real thing, in about a hundred words. The town where the movies were made before Hollywood existed. The neighborhood where New York City quietly runs out. The English city that holds the oldest football club on earth. The Swedish town whose beaches are made of shells. Many places also carry someone who was born there, with their photograph and their story. Explore more than 5,600 places across twenty-one nations and regional groups: the Americas, Taiwan, the British Isles, the Nordics, Oceania and nine more across Europe. Thousands already carry bedtime stories; other parts of the world will open in later versions. Version 1.4 restores missing land around Baja California, nearby islands, and parts of Canada, Alaska and Greenland. SLEEP TOGETHER, APART A Circle is up to sixteen people growing one map. Invite a friend with a code, and their ground appears beside yours wherever the two of you have met. It shows good nights only — never a night you missed, never how long you slept — and it travels through your own iCloud, shared with the people you invited and with nobody else, including us. Leaving a Circle never takes your ground away. HOW A NIGHT WORKS Set your bedtime and your wake time. When bedtime comes, start the night and put the phone down. Pick it back up in the morning within the window you set, and the place is yours. Miss the window and you keep everything you had; you just try again tonight. You can let Apple Health confirm the night for you instead, if you would rather not rely on the phone-down honor system. That is optional, and the app works completely without it. WHAT IT DOES NOT DO No account. No sign-in. No analytics, no advertising, no tracking, and nothing to buy. Your sleep times and your map live on your device and are deleted when you delete the app. We run no server that holds anything about you. Every word you read ships inside the app — the stories, the whole map — so it works on a plane with the wifi off. The photographs load from our image host when there is a connection and fall back to a drawn mark when there isn't. Searching for your hometown goes through Apple Maps, and the app never asks for your location. No streak shaming, no leaderboards, no competition, and no notifications you did not ask for. It's a map of a life, drawn in good nights.

Verdict
The clearest difference is in-app purchases: Sleep Map at none against Keto Clock's 3. Sleep Map also leads on update cadence (every 4 days vs every 2 weeks). Keto Clock's advantage is iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
