Google Health 5.02 brought back nap tracking and hourly activity prompts, two features the 2024 rebrand had quietly removed. The change matters because naps under 90 minutes and sedentary stretches over an hour are the metrics that move daily energy and recovery numbers more than any single sleep night. The best apps for nap and inactivity tracking on Android catch both, without needing a $400 wearable.
We compared seven Android apps for nap-detection accuracy, hourly-inactivity alerts, wearable support, and how much they charge for the features that should be free.
What to look for in a nap and inactivity tracker
- Nap detection that recognizes 20 to 90-minute blocks during the day, not just nighttime sleep.
- Hourly activity prompts that fire after a sit threshold, with optional snooze.
- Wear OS, Samsung Galaxy Watch, or Fitbit support, without requiring a hardware lock-in.
- Honest battery impact. Continuous activity tracking that drains 25% of phone battery isn’t usable.
- Export options. Your sleep and step history should not live solely inside one vendor’s cloud.

The apps worth installing
1. Google Fit — Best for cross-device baseline
Google Fit (Google Health) at 5.02 pulled naps and hourly activity back into the main view. The app aggregates from the phone, Wear OS watches, Fitbit (after the integration), and several third-party platforms, then maps the day into Move Minutes, Heart Points, and now nap blocks.
The hourly activity prompt fires after 60 minutes of detected sit time, with an optional 10-minute snooze. Nap detection uses heart-rate dip and accelerometer pattern from the connected wearable, defaulting to a 20-minute floor.
Where it falls short: Without a wearable, the phone-only tracking is rougher on naps. Some legacy users still see the 2024 sparse-UI bug.
Pricing: Free.
Platforms: Android, iOS, Wear OS.
Download: Google Play
Bottom line: The default Android tracker, finally back to a useful state.
2. Samsung Health — Best for Galaxy ecosystem
Samsung Health is the Galaxy companion app and the deepest integration for Galaxy Watch users. Watch 6 and later detect naps automatically when the user is still and heart rate dips below an individualized threshold.
The Standing Hour mirror of Apple’s hourly-activity ring works the same way: stand for one minute per hour for at least 12 hours.
Where it falls short: Best on Samsung hardware. The non-Galaxy experience is functional but not better than Google Fit.
Pricing: Free.
Platforms: Android. Tighter Galaxy Watch integration than the universal Wear OS Companion.
Download: Google Play
Bottom line: The Galaxy default. Sticky for Samsung users.
3. Fitbit — Best for sleep score depth
Fitbit still ships the deepest sleep analytics on a phone screen, including a Sleep Score per night that breaks out deep, REM, light, and awake time. Naps are detected automatically by Fitbit wearables and folded into the daily score.
The hourly activity feature on Fitbit calls it “Reminders to Move” and fires at 50 minutes past the hour if you’ve moved fewer than 250 steps that hour.
Where it falls short: Best features sit behind Fitbit Premium ($9.99/month). Google’s 2024 acquisition merged data with Google Fit, which annoyed users who’d specifically picked Fitbit for its independence.
Pricing: Free with Fitbit wearable. Fitbit Premium $9.99/month for full sleep analytics, daily readiness, and detailed activity reports.
Platforms: Android, iOS.
Download: Google Play
Bottom line: Worth it if you own a Fitbit wearable.
4. Sleep Cycle — Best for nap quality scoring
Sleep Cycle uses the phone microphone and accelerometer to detect sleep, including daytime naps when you launch the Nap timer. The premium tier adds Sleep Trends, snore detection, and integrations with Google Fit for hourly activity.
The nap timer is the best on this list for short blocks under 45 minutes: it picks an exit window inside the lightest phase to wake you fresh.
Where it falls short: Phone-on-the-bed model. If you don’t sleep with the phone within reach, accuracy drops. Limited wearable integration.
Pricing: Free for basic tracking. Premium $39.99/year.
Platforms: Android, iOS, Wear OS.
Download: Google Play
Bottom line: The strongest dedicated nap app.
5. Mi Fitness — Best for Xiaomi wearables
Mi Fitness is the companion app for Mi Band, Redmi Watch, and Xiaomi Watch lines. The pairing covers nap detection automatically when a Mi Band 8 or later picks up a 20-minute-plus rest block during the day.
Hourly idle alert fires after configurable thresholds (default 60 minutes), and the app exports to Google Fit and Apple Health for users who prefer those as the system of record.
Where it falls short: Tied to Xiaomi hardware for the best features. The standalone phone experience is limited.
Pricing: Free.
Platforms: Android, iOS.
Download: Google Play
Bottom line: Essential if you’re already in the Xiaomi ecosystem.
6. Sleep as Android — Best for open data and Wear OS
Sleep as Android is the long-running power-user app for Android sleep tracking. The data is yours; export to CSV, sync to Google Drive, integrate with Tasker. The Wear OS companion detects naps via heart-rate dip and writes the block back to the phone.
The hourly activity reminder runs on the phone via configurable Tasker-style triggers.
Where it falls short: Setup is heavier than most apps on this list. Some users found the recent UI revamp less approachable than the prior generation.
Pricing: Free trial. One-time purchase $5.99 to $29.99 depending on add-on packs. No subscription.
Platforms: Android, Wear OS.
Download: Google Play
Bottom line: The right pick for users who want their data and don’t want a subscription.
7. Withings Health Mate — Best for multi-device clinical detail
Withings Health Mate is the companion to Withings ScanWatch, Body smart scales, and Sleep mats. The under-mattress Sleep mat detects naps without any wearable, which is the most accurate consumer nap solution on the market.
Hourly activity prompts integrate with Withings watches that vibrate when sit time crosses the threshold.
Where it falls short: Best features require Withings hardware. The Sleep mat alone is around $130.
Pricing: Free with Withings devices. Withings+ subscription $9.99/month for advanced metrics.
Platforms: Android, iOS.
Download: Google Play
Bottom line: The right pick when accuracy matters more than budget.
How to pick the right one
- If you have no wearable: Google Fit, plus a phone-only Sleep Cycle for naps.
- If you have a Galaxy Watch: Samsung Health.
- If you have a Fitbit: Fitbit, with Premium only if you want the sleep score depth.
- If you have a Mi Band: Mi Fitness.
- If you want your data exported and no subscription: Sleep as Android with the Wear OS companion.
- If you have a Withings Sleep mat: Health Mate, no question.
