Apple Watch Series 12 is rumoured to add 24/7 heart-rate tracking as its headline health upgrade. Android already has the sensor coverage; the question is which app actually turns your Galaxy Watch, Pixel Watch, or Xiaomi band into a proper continuous heart monitor rather than a spot-check gadget. We tested seven best apps for continuous heart-rate tracking on Android and looked at sampling frequency, resting heart-rate accuracy against a chest strap, sleep-time behaviour, and how each one exports its data.
What to look for in a continuous heart-rate app
Continuous does not mean every second. Most wearables sample every one to five minutes at rest and shift to real-time during workouts. What matters:
- Sampling cadence. Some apps ping the sensor every minute round the clock. Others sleep the sensor between bursts to save battery.
- Alerts. High and low heart-rate warnings only work if the app runs the check in the background.
- Battery cost. Continuous sampling burns 10–20% more watch battery per day. Some apps let you tune the trade-off.
- Data export. CSV or FIT exports matter for anyone taking numbers to a cardiologist. A few apps still trap data in the vendor cloud.
- Third-party wearable support. Some apps only pair with their own brand. Others accept Bluetooth chest straps and cross-brand watches.

The 7 best apps for continuous heart-rate tracking on Android
1. Samsung Health, best for Galaxy Watch owners
Samsung Health turns Galaxy Watch heart-rate sampling from spot-check to continuous once you enable it in the app. The one-minute sampling mode covers waking hours and sleep, and the app now shows resting heart-rate trends across weeks with clear graphs. Blood-pressure and ECG features work in supported regions.
Where it falls short: Cross-brand wearables barely work. Third-party watch pairing is a token feature.
Pricing:
- Free: full feature set with Galaxy Watch
- Paid: no paid tier for tracking
Platforms: Android (Wear OS 3+, Tizen legacy)
Download: Google Play · Samsung Galaxy Store · Aptoide
Bottom line: Best pick if you own a Galaxy Watch. Skip if you use anything else.
2. Google Fit, best for Wear OS phones and watches
Google Fit integrates directly with Health Connect on Android 14 and later, which means every Wear OS heart-rate reading rolls into one place. Continuous heart-rate on Pixel Watch samples every minute and pushes to Fit automatically. The workout auto-detection has improved noticeably in the past year.
Where it falls short: Resting heart-rate reporting is buried in the timeline. Alerts for high or low heart rate are less prominent than in vendor-specific apps.
Pricing:
- Free: full feature set
- Paid: no paid tier
Platforms: Android (Wear OS), iOS
Download: Google Play · Aptoide
Bottom line: Best pick for Pixel Watch and any Wear OS device. The default that other apps sync into.
3. Fitbit, best for long-term resting heart-rate trends
Fitbit still has the cleanest resting heart-rate graph in the category. Continuous heart-rate sampling has been the default since the Charge 2 era, and the app now hosts Pixel Watch data alongside Fitbit devices. Premium adds Daily Readiness, which weights resting heart rate as one of its inputs.
Where it falls short: Premium ($9.99 per month) gates the more useful sleep and readiness analyses. The Google account migration was rough for some legacy Fitbit users.
Pricing:
- Free: heart rate, step count, sleep summary
- Paid: Premium at $9.99 per month for readiness and detailed sleep
Platforms: Android, iOS, web
Download: Google Play · Aptoide
Bottom line: Best pick if resting heart-rate trend graphs are what you care about most.
4. Mi Fitness, best for Xiaomi bands and watches
Mi Fitness is the current app for Xiaomi Smart Band, Redmi Watch, and Xiaomi Watch models. Continuous heart-rate sampling runs at one, five, or ten minute intervals depending on the band model, and stress-level tracking works off the same sensor. The one-minute mode drops band life from 14 days to about eight, which is still class-leading.
Where it falls short: Sync outside Xiaomi devices is limited. Third-party fitness apps often need to go through Zepp Life for older bands.
Pricing:
- Free: full tracking
- Paid: no paid tier
Platforms: Android, iOS
Download: Google Play · Aptoide
Bottom line: The right pick for any Xiaomi Smart Band or watch. Cheap hardware plus continuous sampling.
5. Huawei Health, best for Huawei Band and Watch owners
Huawei Health handles the Huawei Band 9, Watch GT series, and Watch 4 line. Continuous heart-rate sampling here runs every ten minutes by default and drops to real-time during workouts. Sleep-time SpO2 and skin-temperature tracking round out the always-on suite.
Where it falls short: The AppGallery-only install path is friction for people outside China. Some sync features stall on non-Huawei phones.
Pricing:
- Free: full feature set
- Paid: no paid tier
Platforms: Android (via AppGallery), iOS
Download: Aptoide
Bottom line: The right pick if you own a Huawei wearable. Cross-platform sync is limited.
6. Polar Flow, best for cross-brand sport watches
Polar Flow works with Polar heart-rate straps and watches, but also imports data from H10 chest straps paired to third-party apps. Recovery Pro and Nightly Recharge use continuous heart-rate to score sleep-time recovery, and the CSV export is clean.
Where it falls short: The interface still shows its endurance-sport roots. Casual users find it dense.
Pricing:
- Free: full tracking and analysis
- Paid: no paid tier (Polar Club optional for group coaching)
Platforms: Android, iOS, web
Download: Google Play · Aptoide
Bottom line: Best pick if you already own an H10 chest strap or want data-heavy analysis.
7. Garmin Connect, best for Garmin wearables
Garmin Connect manages every Garmin watch, from Forerunner to Fenix to Venu. Continuous heart-rate at one-minute cadence runs by default on every current model, and the Body Battery metric uses that stream to guess your energy budget for the day. Data export covers CSV, FIT, and TCX for cardiology-grade portability.
Where it falls short: Only useful with a Garmin device. Watch prices are higher than most competitors on this list.
Pricing:
- Free: full sync and analysis
- Paid: no paid tier
Platforms: Android, iOS, web
Download: Google Play · Aptoide
Bottom line: The one to pair with any Garmin wearable. The best export story in the category.
How to pick the right heart-rate tracking app
Match the app to the wearable. Samsung Health goes with a Galaxy Watch, Mi Fitness with a Xiaomi band, Garmin Connect with a Garmin, Huawei Health with a Huawei device. Cross-pairing rarely works well.
Pick Google Fit if you have a Pixel Watch or any Wear OS 4 watch. Health Connect makes it the natural hub.
Pick Fitbit if you want the cleanest long-term resting heart-rate graph and are willing to pay for Premium.
Pick Polar Flow if you own an H10 chest strap or want the deepest sleep-time recovery analysis.
Pick Garmin Connect if you already invested in the Garmin ecosystem or need CSV/FIT export for a doctor.
Stay on the vendor app for the wearable you own. The value of switching is small compared to the friction of losing history.
FAQ
What is the best app for 24/7 heart-rate tracking on Android?
Samsung Health for Galaxy Watches, Google Fit for Pixel Watch and Wear OS, and Fitbit for Fitbit and Pixel Watch users. All three record heart rate continuously when the wearable supports it.
Does continuous heart-rate tracking drain the battery?
Yes. One-minute sampling drops most wearables’ battery life by 10 to 20 percent per day. Five- or ten-minute intervals are a workable compromise for most people.
Can I export my heart-rate data to a doctor?
Garmin Connect, Polar Flow, and Fitbit (via Google Takeout) all offer CSV or FIT exports. Samsung Health and Mi Fitness export is more limited but works through Health Connect on Android 14 and later.
Are Android heart-rate readings accurate?
Wearable optical heart-rate sensors match a chest strap within a few beats per minute at rest. Accuracy drops during high-intensity intervals. A dedicated chest strap remains the gold standard for training zones.
Do I need a subscription for continuous heart-rate tracking?
No. Every app on this list offers continuous heart-rate for free. Premium tiers add readiness, sleep, or coaching analyses on top.
