The best heart rate monitor that connects to your phone is the COOSPO H6, thanks to its Bluetooth and ANT+ support, broad app compatibility and replaceable battery. Choose the COROS monitor for a soft armband, a MorePro tracker for all-day trends, or the EMAY 6L for ECG recording.
A phone-connected monitor can do more than show a number during a workout. The right device can send heart rate to an iPhone or Android phone, record sessions in a fitness app and share data with a watch, treadmill or bike computer.
If you want the basics first, our heart rate monitor buying guide explains chest straps, armbands, watches and phone connections.

The best heart rate monitor that connects to phone for each use
The COOSPO H6 is the best overall choice for workout apps, while COROS and COOSPO offer armband designs. The remaining picks cover all-day tracking, ECG records, long battery life and cycling equipment.
COOSPO H6 Heart Rate Monitor Chest Strap: Best for app-connected workouts
- Bluetooth and ANT+
- Works with smartphones and fitness apps
- 300-hour battery life
- IP67 rain and sweat protection
The COOSPO H6 is the strongest all-around choice for recording workout heart rate on a phone. Bluetooth and ANT+ support also gives it flexibility with watches, bike computers and gym equipment.
Pros
- Dual wireless modes
- Broad app support
- Replaceable CR2032 battery
Cons
- Requires wetting the electrode areas
- Do not use for swimming
The COOSPO H6 Heart Rate Monitor Chest Strap is the strongest match for recording exercise heart rate on an iPhone or Android phone. It sends data through Bluetooth or ANT+, so you can also use it with compatible sports watches, bike computers and gym equipment.
The H6 works with apps that include Strava, Wahoo Fitness, Polar Beat, Zwift, Peloton and CooSpoRide. Pair it inside the app rather than searching for it in the phone's regular Bluetooth menu.
Its replaceable CR2032 battery supports about 300 hours of use. The chest strap has IP67 protection for rain and sweat, but it isn't intended for swimming or soaking.
Moisten the electrode areas before wearing it. A snug fit and clean contact help the sensor send data to your phone during movement.
Choose the H6 if you want the widest connection options in this group. It is also a good fit for treadmill users, since the product supports several treadmill and indoor training systems.
COROS Heart Rate Monitor: Best for a comfortable armband
- Bluetooth connection
- Pairs with up to 3 devices
- 38 hours of operation
- Wear detection
The COROS Heart Rate Monitor uses a soft armband instead of a chest strap and can pair with up to 3 devices. Its automatic wear detection starts and stops the monitor when you put it on or remove it.
Pros
- Soft fabric band
- Automatic wear detection
- Quick-clean sensor design
Cons
- No ANT+ support
- Shorter operating time than replaceable-battery straps
The COROS Heart Rate Monitor is the best pick if you prefer an armband over a chest strap. Its soft, breathable band wraps around the arm, and the sensor can be removed for cleaning.
Bluetooth is the only wireless protocol here, so it won't connect to ANT+ devices. It can pair with up to 3 devices at once, including phones, sports watches, indoor trainers, treadmills and rowing machines.
Wear detection powers the monitor on and off based on whether it is being worn. The battery provides 38 hours of operation or up to 80 days of standby, with charging through the included magnetic cable.
The large band fits arm sizes from 9.4 to 16.9 in. Check the fit before ordering, especially if your upper arm is outside that range.
Choose COROS for a phone-connected armband with automatic wear detection. Pick the COOSPO armband instead if ANT+ support matters.
COOSPO Armband Heart Rate Monitor: Best for Bluetooth and ANT+ armband use
- Optical heart rate sensor
- Bluetooth and ANT+
- 25-plus hours per charge
- Two fabric straps
This COOSPO armband gives phone users the comfort of an upper-arm sensor while keeping both Bluetooth and ANT+ compatibility. It also works with many fitness apps, sports watches and gym devices.
Pros
- Dual connection modes
- Rechargeable battery
- Two straps included
Cons
- Needs charging between workouts
- Do not use for swimming
The COOSPO Armband Heart Rate Monitor combines an upper-arm fit with Bluetooth and ANT+ support. That makes it useful for phone apps, Garmin and Wahoo watches, Peloton equipment and other compatible training devices.
Its optical sensor records real-time exercise heart rate, training zones and calories in supported apps. App compatibility includes Strava, Polar Beat, Runkeeper and Map My Fitness.
The rechargeable battery supports more than 25 hours per charge. Two fabric straps are included, which can help if you want one strap available while the other is being cleaned.
The armband has IP67 protection for sweat and rainy training, but it is not intended for swimming. Press the start button before a workout and check for the blue connection light.
Choose this model if you want an armband but still need ANT+. It is a more flexible connection choice than a Bluetooth-only monitor.
MorePro Fitness Tracker with 24/7 Heart Rate: Best for all-day wellness tracking
- 24/7 heart rate monitoring
- iOS and Android support
- 120-plus sport modes
- Up to 7 days of normal use
The MorePro Fitness Tracker is better suited to daily health and activity trends than focused workout recording. It supports iOS and Android phones, tracks heart rate throughout the day and includes more than 120 sport modes.
Pros
- Longer daily battery life
- Heart rate, sleep and activity tracking
- Call and app notifications
Cons
- No GPS built in
- Wellness device, not a medical device
The MorePro Fitness Tracker with 24/7 Heart Rate is the best choice for all-day phone-connected tracking. It records heart rate throughout the day and also includes blood pressure trends, blood oxygen checks, sleep tracking and activity data.
This is a smartwatch-style tracker rather than an external workout sensor. It supports more than 120 sport modes, including running and walking, and works with Android 7.0 or newer and iOS 13.0 or newer phones.
A full charge takes about 2 hours. Normal use lasts up to 7 days, while standby can reach 15 days.
The tracker also shows calls, texts and app notifications on the wrist.
The device has no built-in GPS. It can still suit phone users who want activity records and notifications without buying a dedicated GPS sports watch.
Choose MorePro for daily wellness trends and routine activity. For a chest-mounted workout sensor, the COOSPO H6 is a better match.
EMAY 6L Portable ECG Monitor: Best for ECG records on a phone
- Six-channel ECG recording
- Bluetooth phone connection
- USB PC connection
- No subscription required
The EMAY 6L is the specialist option for recording ECG signals and displaying heart rate through a phone or computer. It is not a replacement for hospital diagnostic equipment.
Pros
- Six-channel ECG recording
- Works with iOS and Android phones
- No subscription required
Cons
- Not designed for continuous workout wear
- Pacemaker users are advised not to use it
The EMAY 6L Portable ECG Monitor is the specialist choice for recording ECG signals through a phone. It connects to iOS and Android phones over Bluetooth and to Windows or Mac computers through USB.
It records ECG data in 6 channels and displays heart rate for home health care use. The mobile and PC software can provide sample mode, time settings, case uploads, case review and measurement tools.
The built-in rechargeable battery means you don't need a disposable battery for each recording. There is also no subscription requirement.
This isn't a wearable workout monitor. It is a handheld ECG device, and EMAY states that it is not a substitute for hospital diagnostic equipment.
People with implanted pacemakers are advised not to use it.
Choose EMAY when ECG records are the main need. Choose a chest strap or armband for continuous workout data.
ICOMTOFIT Smart Watches for Women: Best for a smartwatch with heart rate tracking
- Heart rate and SpO2 monitoring
- More than 100 sports modes
- iOS and Android support
- 5 to 7 days of normal use
The ICOMTOFIT smartwatch combines heart rate tracking with calls, notifications, sleep data and more than 100 sports modes. It suits phone users who want one wrist device for workouts and daily routines.
Pros
- Large 1.83-inch screen
- Phone notifications and calls
- GPS via smartphone
Cons
- Not a dedicated external heart rate sensor
- Health features are for daily reference
The ICOMTOFIT Smart Watches for Women suits buyers who want heart rate tracking plus everyday smartwatch tools. It monitors heart rate, blood oxygen and stress, while the phone connection handles notifications and smartphone-assisted GPS.
The watch supports more than 100 sports modes, including walking, running, cycling, yoga and hiking. It also records steps, distance, active minutes and calories during daily activity.
A 1.83-inch touchscreen shows calls, messages and fitness information on the wrist. Battery life is 5 to 7 days under normal use, with up to 20 days of standby time.
The IP67 design is intended for hand washing, sweat and light rain splashes. It isn't a dedicated external sensor, so choose it for general activity tracking rather than the most focused workout setup.
Choose ICOMTOFIT if you want one watch for heart rate, notifications and daily tools. For a phone-only workout setup, the COOSPO H6 costs less space on your wrist.
GEOID HS500 Heart Rate Monitor: Best for long battery life
- Bluetooth and ANT+
- 800-hour battery life
- Chest strap design
- Works with phones, treadmills and bike computers
The GEOID HS500 is a practical chest strap for buyers who want long battery life and dual wireless protocols. Its phone connection should be made inside the workout app rather than the phone's Bluetooth settings.
Pros
- Long replaceable-battery life
- Bluetooth and ANT+
- Connection light confirms startup
Cons
- Chest strap needs damp electrode areas
- Swimming is not recommended
The GEOID HS500 Heart Rate Monitor is the best pick for buyers who want a chest strap with a long replaceable-battery life. Its CR2032 battery supports about 800 hours, and the sensor uses both Bluetooth and ANT+.
The HS500 connects to smartphones, tablets, sports watches, bike computers, treadmills and other compatible fitness equipment. Bluetooth app support includes Strava, Zwift, Kinomap, Wahoo Fitness and Nike Run Club.
An LED flashes during startup to confirm that the sensor is active. The strap also uses automatic wake-up after it is worn.
As with other chest straps, wet the electrode area and adjust the strap so it sits against your skin. Search for the sensor in the workout app, not in the phone's normal Bluetooth settings.
Choose GEOID if battery changes are an occasional task you want to avoid. The Magene H64 lasts longer on paper, but GEOID has a lower score for this phone-focused roundup.
MorePro Health Fitness Tracker: Best for a slim daily tracker
- 24/7 heart rate monitoring
- 1.47-inch display
- Seven sport modes
- Up to 7 days of daily use
The MorePro Health Fitness Tracker keeps the focus on daily activity, sleep and wellness trends in a slim wrist design. It works with Android 7.0 and iOS 13.0 or newer smartphones.
Pros
- Slim 1.47-inch display
- Daily heart rate and sleep tracking
- Seven sport modes
Cons
- Not compatible with PCs, iPads or tablets
- Not a medical device
The MorePro Health Fitness Tracker is a slim option for daily heart rate, sleep and activity records. Its 1.47-inch display keeps the design smaller than many full smartwatches.
It tracks heart rate throughout the day, records light and deep sleep and supports 7 sport modes. The phone app also includes blood pressure and blood oxygen features for general wellness reference.
The tracker works with Android 7.0 and iOS 13.0 or newer phones using Bluetooth 5.3 or above. Battery life reaches up to 7 days of daily use or 10 days on standby.
It isn't compatible with PCs, iPads or tablets. Choose it when your main screen is an Android phone or iPhone and you want a compact wrist tracker.
Magene H64 Heart Rate Monitor: Best for long-term cycling sessions
- Bluetooth and ANT+
- 1,000-hour battery life
- Chest strap design
- Connects to phones, watches and fitness equipment
The Magene H64 is a cycling-focused chest strap with Bluetooth and ANT+ transmission. Its long stated battery life and support for bike computers, sports watches and phones make it useful for frequent riders.
Pros
- Longest stated battery life here
- Dual transmission
- Supports simultaneous ANT+ and Bluetooth recording
Cons
- Requires correct electrode placement
- Actual battery life can vary with use
The Magene H64 Heart Rate Monitor is the battery-life choice for cyclists and frequent trainers. Its stated battery life reaches 1,000 hours, and it can send data through ANT+ and Bluetooth.
You can record through an ANT+ device and a Bluetooth app at the same time. The H64 also supports bike computers, sports watches, Peloton bikes, NordicTrack treadmills, iFIT treadmills and other fitness equipment.
Magene lists compatibility with Strava, Zwift, Wahoo Fitness, TrainerRoad, Rouvy, Nike Run Club and other apps. The sensor enters a sleep state after the strap is removed to save power.
Wet the electrode area, place the Magene logo upright and keep the strap close to your skin. Actual battery life can vary with use, even though the stated figure is the longest in this group.
Choose Magene if you cycle often and want one strap for phone apps and ANT+ equipment. The COOSPO H6 is the better overall pick when you want a higher score and broader general use.
How we compared heart rate monitors for phone use
The best heart rate monitor for iPhone or Android needs more than a heart rate sensor. We compared the connection method, wear style, app support, battery setup and the kind of data each device is designed to record.
Our score weighs specs, features and buyer feedback against what you're shopping for. A chest strap can rank above a smartwatch for workout recording, while a smartwatch can be the better fit for all-day tracking.
Bluetooth connection matters for iPhone users
An iPhone generally needs a Bluetooth-compatible sensor for direct phone connection. The COOSPO H6, COROS, COOSPO armband, MorePro trackers, EMAY 6L, ICOMTOFIT and GEOID HS500 all include Bluetooth in their connection details.
ANT+ adds flexibility with supported watches, bike computers and gym equipment, but it isn't required for phone use. The COROS monitor is Bluetooth only, while the other dedicated workout straps in this group support Bluetooth and ANT+.
Pair the sensor inside the fitness app
Several chest straps advise pairing inside the app rather than through the phone's system Bluetooth menu. Open the app's sensor or accessories screen, wake the monitor and follow the app's pairing steps.
This matters for the COOSPO H6, GEOID HS500 and Magene H64. If your phone sees the sensor but the workout app does not, remove the system-level connection and try the app's pairing screen.
For more options, compare our guide to the best Bluetooth heart rate monitor.
Chest straps suit focused workout recording
Chest straps such as the COOSPO H6, GEOID HS500 and Magene H64 use electrode areas that sit against the torso. Wet the electrode areas before exercise and adjust the strap so it stays close to your skin.
The main advantage is a dedicated workout sensor that can send heart rate to a phone, watch or compatible machine. The tradeoff is that you must put on a separate strap and keep the contact areas ready.
Our best heart rate monitors for treadmill workouts covers the features that matter when the monitor needs to work with indoor training equipment.
Armbands can be easier to wear
Armbands place the sensor around the upper arm and can feel preferable if you don't like a strap around your chest. COROS uses Bluetooth only, while the COOSPO armband supports both Bluetooth and ANT+.
Check the sizing before you choose an armband. COROS gives a large-band range of 9.4 to 16.9 in, while the COOSPO armband includes two fabric straps.
Smartwatches are better for all-day information
The MorePro and ICOMTOFIT watches track heart rate during the day and combine it with sleep, activity or notification features. They are useful if you want heart rate on your wrist without carrying a separate sensor.
These devices are for general wellness and fitness reference. Their heart rate, blood oxygen and blood pressure features should not be treated as a medical diagnosis.
If you want to use a watch with an external sensor, see our guide to the best heart rate monitor for Apple Watch.
Which heart rate monitor works best with Strava?
The COOSPO H6 is the best overall Strava choice because it supports Bluetooth and ANT+ and lists Strava among its compatible apps. The COOSPO armband, GEOID HS500 and Magene H64 also list Strava support.
For a phone-only setup, Bluetooth is the key connection. For a bike computer or sports watch, ANT+ can add another connection path.
Read our best heart rate monitors for Strava comparison if Strava is the main app you use.
How to choose a heart rate monitor for iPhone
Choose the COOSPO H6 if you want the most flexible workout sensor for an iPhone. Its Bluetooth connection works with smartphones, while ANT+ supports compatible training equipment and sports watches.
Choose COROS if you want a soft armband and up to 3 Bluetooth connections. Choose the COOSPO armband if you want an armband with both Bluetooth and ANT+.
Choose MorePro or ICOMTOFIT if you want all-day heart rate tracking on your wrist. Choose EMAY if you need ECG records rather than continuous exercise monitoring.
Battery setup should also guide your choice. The Magene H64 has the longest stated battery life, the GEOID HS500 has 800 hours and the COROS monitor trades replaceable-battery convenience for automatic wear detection and charging.
Do you need an app for a phone-connected heart rate monitor?
You usually need a compatible fitness app to view or record data from a Bluetooth heart rate sensor. Chest straps may not show data on their own because they send the reading to a phone, watch, bike computer or treadmill.
If you want a heart rate monitor that can work without an app, compare our best heart rate monitors without an app guide. A smartwatch may show data on its own screen, but its setup can still rely on a phone app.
What heart rate zone should you use during cardio?
A heart rate monitor can help you watch your workout intensity, but the right zone depends on your age, fitness, exercise history and health. Use the reading as a training reference, not a diagnosis.
For treadmill sessions, our guide explains what is a good treadmill heart rate zone for cardio. Stop exercising and seek medical advice if you have concerning symptoms.
Verdict: which heart rate monitor connects to your phone best?
The COOSPO H6 is the best heart rate monitor that connects to phone apps for most workout users. Pick COROS for a comfortable Bluetooth armband, MorePro for all-day tracking, EMAY for ECG records and Magene for long battery life during cycling.
Choose the device by how you train. A chest strap fits focused exercise, an armband offers a different fit, and a smartwatch adds daily health and notification features around the phone connection.

Choose an armband if you prefer not to wear a chest strap.
Can a heart rate monitor connect directly to an iPhone?
Yes. Bluetooth heart rate monitors can connect to an iPhone through compatible fitness apps.
For the COOSPO H6, GEOID HS500 and Magene H64, search for the sensor inside the app instead of pairing through the iPhone Bluetooth settings.
What is the difference between a chest strap and an armband?

The EMAY 6L records ECG signals but is not intended to replace hospital diagnostic equipment.
Seek medical advice for concerning symptoms.
