Live heart rate sharing
Your coach sees every beat, as it happens.
HeartShare streams your live pulse from a Bluetooth monitor or smartwatch straight to your coach — in the gym, on the track, or half a world away.

What is HeartShare?
HeartShare is a real-time heart rate sharing app for athletes and coaches. The athlete broadcasts live BPM from a Bluetooth heart rate monitor or smartwatch, shares a short access key, and the coach follows the session live from their own phone — over Wi-Fi or mobile data, anywhere in the world.

How it works
Three steps from pairing to live coaching
No passwords to hand out, no cables, no waiting for the session to end to see the data.
1
Pair your monitor
Open HeartShare and connect a Bluetooth LE chest strap, armband or your smartwatch. Your live BPM appears instantly on screen.
2
Share your access key
Start a session and the app generates a short access key. Send it to your coach however you like — message, call, or read it out.
3
Train while they watch
Your coach enters the key and sees your pulse, zone and trend in real time, then reviews avg, max and min when the session ends.
Features
Built for the way coaching actually happens
Everything on one screen while you're moving — and nothing you have to fiddle with mid-set.
Coach view, no payment
Coaches join a session with the athlete's access key and monitor live for free. No subscription, no seat licence.
Works with your gear
Bluetooth LE straps, armbands and smartwatches — including Apple Watch. Train with the monitor you already own.
Audio heart rate
Optional audible pulse lets a coach hear the athlete's beat in real time while watching form instead of a screen.
Session summary
Average, max and min BPM with the full trend, ready the moment the session stops. Nothing to export or sync.
Minimal data, by design
Sign-in and subscription status only — enough to restore your purchase. We never sell personal data to third parties.

FAQ
Questions about HeartShare, answered
Is HeartShare free?
Yes — HeartShare is free to download on iOS and Android, and the coach view is free to use with no subscription. A paid subscription removes ads and unlocks extended athlete features in the app.
Do coaches need to pay?
No. The coach view is free — no subscription is required. The coach enters the athlete's access key in the app and starts watching the live session.
How does a coach join my session?
Start sharing in the app, then send the generated 10-character access key to your coach. They open HeartShare, choose the coach role, enter the key and your live heart rate appears on their screen.
Which devices can HeartShare read heart rate from?
Any standard Bluetooth Low Energy heart rate monitor — chest straps, armbands and compatible smartwatches — plus Apple Watch on iOS. Tested with Apple Watch, Garmin watches, Garmin, Coospo, Moofit, Polar and Wahoo straps, Whoop and Xiaomi Mi Band 10. The pairing guide lists step-by-step instructions per device.
Does HeartShare work remotely?
Yes. Sharing runs over Wi-Fi or mobile data, so your coach can follow the session from another gym, another city or another country.
How long does a session last, and is my heart rate stored?
A session runs until the athlete stops it, or ends automatically after 2 hours. Heart rate is processed only during the session — it is not stored after the session ends and is never used for advertising or marketing.
Is HeartShare available on Android?
Yes. HeartShare is on Google Play for Android phones, alongside the iOS version on the App Store. Athletes and coaches can be on different platforms in the same session.
What data does HeartShare collect?
Minimal data: your email or sign-in identifier, and subscription status so purchases can be restored across devices. The free version shows ads via AdMob, which may collect device identifiers.
We do not sell personal data to third parties. You can delete your account and data at any time.
Is HeartShare a medical device?
No. HeartShare is a training and fitness tool for sharing heart rate data between athletes and coaches. It is not intended for diagnosis or medical monitoring.
