No wearables, no AI, no background drain. Just tap to log when you sleep and wake.

You tap one button to switch between two states: SLEEPING / AWAKE.
Going to bed? Tap. Waking up? Tap again. Each tap adds a precise timestamp to your log.

⭐ What this app does
Keeps a manual sleep time log with exact timestamps
Lets you track how many hours you actually sleep, even with an irregular schedule
Works offline, doesn’t run in the background, and doesn’t drain your battery: zero background activity - truly battery-friendly.
Needs only one thing from you: remember to tap the button
This is not a smart gadget, not a medical device, and not an AI assistant.
It’s a clean, focused sleep time log that you control yourself.

📊 Two types of logs
The app keeps two separate logs:
• Event log - every tap with date, time and state (went to sleep / woke up).
• Daily summary log - the total time spent in each state for every calendar day.
You can always see both: what exactly happened and how much time it all adds up to.

📈 Clear sleep graphs
There is a dedicated graphs page so you can see your sleep pattern at a glance:
• Daily graph - today’s SLEEP / AWAKE segments as a stacked bar
• Monthly graph - your sleep pattern over days in a month
Graphs visually show when you were asleep or awake, helping you notice your own rhythm.

⏱️ Three live timers on the main screen
The main screen shows:
• Main timer - current state (SLEEPING or AWAKE) and its running duration
• Two smaller timers - show today’s totals for each state
• Seconds are constantly ticking, so you always see how long your current state has been active and how your day is building up.

🧑‍💻 Created for real life, not for perfect schedules
I originally built this app for myself.
My sleep is messy: no fixed bedtime, no stable schedule, often short naps and broken nights. I wanted to know how many hours I actually sleep, not how many I planned to sleep.

This app is for that kind of reality:
• irregular sleep
• night shifts
• naps during the day
• track naps and fragmented sleep with precision
• random wake-ups and going back to bed

📵 No gadgets required
The advantage of this simple “sleep diary” is that it:
• doesn’t require a fitness tracker or smartwatch
• works on a regular smartphone (even older Android versions)
• doesn’t run all the time in the background
• only writes to the log when you tap the button
• Just you, your phone, and one button.

👨‍👩‍👧 Who can use it
Parents who want to track baby sleep precisely
• People caring for elderly relatives
• Anyone with an irregular sleep schedule
• Anyone who wants raw, accurate sleep time records without extra noise
• The app doesn’t tell you how to sleep - it shows you exactly how much you actually slept.

📤 Export your sleep records
There is a Share / Export function to save your log as a CSV file.
You can:
• send it to yourself by email or messenger
• open it in Excel, Google Sheets, or any CSV-compatible app
• analyze your sleep time as you wish

⚠️ Important note
This app does not provide medical recommendations, diagnoses, or advice.
It only keeps an accurate log of your sleep and awake time.
All decisions about your health and sleep habits are up to you and your doctor. ## Rankings - #1,459,106 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `ru.microsave.timesleep.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Offline Sleep Journal](https://chrome-stats.com/d/com.sleep.journal) — 48,668 users, 2.67 / 5 - [Sleep Diary & Bedtime Tracker](https://chrome-stats.com/d/com.hydroponicglass.sleep_diary) — 777 users - [RestLog: Sleep Tracker](https://chrome-stats.com/d/com.restlog.app) — 1 users - [onSleep: Bedtime Sleep Tracker](https://chrome-stats.com/d/com.appsix.onsleep) — 308 users - [Sleep Hours Logger Tracker](https://chrome-stats.com/d/com.wellness.sleeproutine.journal) — 19 users - [Sleep Tracker](https://chrome-stats.com/d/com.restwell.sleeptracker) — 16 users - [Sleep Pattern Tracker](https://chrome-stats.com/d/app.sleeppattern.tracker) — 3 users - [Sleep Log](https://chrome-stats.com/d/com.minipro.sleeplog) — 5 users - [Sleep Tracker, Log Sleep Hours](https://chrome-stats.com/d/com.ataraxy.sleep_tracker) — 24 users - [SleepRight: Sleep Journal](https://chrome-stats.com/d/com.clearstackapps.sleepright) — 11 users - [Sleep Diary](https://chrome-stats.com/d/com.sleepdiary.nightjournal) — 93 users - [Automatic Sleep Tracker](https://chrome-stats.com/d/il.festinger.logsleeptocalendar) — 271 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/ru.microsave.timesleep)
