For personal trainers
Two clients.
One screen.
Coach Heart Rate is real-time heart rate tracking for coaches. Follow two clients' heart rates and zones at the same time – on the treadmill, in the gym or outdoors.


Use cases
Built for coaches training two clients at once
Run a partner session or a small group of two and still see each client's exact effort level. The app estimates maximum heart rate from birth year and splits it into five zones, so every workout stays at the right intensity.
On the treadmill
Two clients on side-by-side treadmills – see both heart rates and zones at a glance.
In the gym
Partner training, circuits or strength work: know when a client has recovered for the next set.
Outdoors
Runs, hill repeats and outdoor sessions – phone in your pocket, Bluetooth straps on your clients.

Bluetooth sensors
Connect a standard chest strap for each client.
Audio cues
Hear changes without staring at the screen.
No account
No sign-up and no user account.
FAQ
Frequently asked questions
Does the app really support two clients at the same time?+
Yes. The screen splits into two views, each with its own heart rate, zone bar and workout time. You can also use it for a single client.
What equipment do I need?+
A standard Bluetooth heart rate chest strap for each client you want to track. Any sensor that supports the common Bluetooth heart rate profile works.
How is maximum heart rate calculated?+
The app estimates it from the client's birth year and shows five intensity zones. For exact limits, use a fitness test.
Does it work on the treadmill, in the gym and outdoors?+
Yes. The app runs in your phone's browser, so you can use it anywhere – the sensor range is roughly 10 metres, which covers side-by-side treadmills and most gym layouts.
Do I need to create an account?+
No. There is no sign-up, no login and nothing to install. Open the app and start training.
Where is my clients' data stored?+
On your own device only. Names, birth years and heart rate data are never sent to our servers.
