Automatic Sleep Tracker

Finally, a sleep tracker that works without any effort from you. Most sleep apps make you tap a button before bed. Sleeper doesn't. Just plug in your phone as usual, go to sleep, and wake up to find your sleep duration already logged — automatically. How it works Sleeper silently monitors simple phone signals — screen state, charging status, and device activity — to detect when you fell asleep and when you woke up. No microphone. No constant GPS. No battery drain. No wearable required. Features Fully automatic sleep detection — no manual activation ever Daily sleep duration log Beautiful graphs — view your sleep history by day, week and month Spot trends and see your averages at a glance Log sleep sessions directly to your Google Calendar — keep all your data in one place Simple, clean sleep history timeline Gentle morning notification showing last night's sleep Completely private — all data stored locally on your device No account required No subscription Why Sleeper? Other trackers require expensive smartwatches or wristbands. Others make you remember to tap "start" before bed every single night. Sleeper does neither. It just works quietly in the background, building your sleep history day by day without you thinking about it. The calendar integration makes it uniquely useful — your sleep becomes part of your daily schedule, visible alongside your appointments and commitments. See exactly how life events affect your sleep over time. Perfect for: People who forget to activate sleep trackers Anyone without a smartwatch or fitness band Minimalists who want simple, clean data People who live by their Google Calendar Anyone curious about their sleep patterns without the hassle Your sleep data stays on your phone. Always. What's the actual app name on the Play Store? I can tailor the ASO keywords too if you want to optimize discoverability.
