Frequently Asked Questions

Which heart rate monitors are compatible?

Heart Rate Ninja is compatible with most popular Bluetooth LE heart rate monitors. Click here to learn more.

Can multiple people use the same monitor?

Yes! Multiple gym members can share the same heart rate monitor (as long as they're not using it at the same time).

Just follow the steps below:

  1. Create a profile for each gym member
  2. Assign the same heart monitor to each profile
  3. Disable the 'auto add nearby profiles to workout' toggle (on the home screen). Otherwise, both profiles will be added to the workout when the monitor is detected.
Is there a maximum range for the monitors?

The max range will vary based on environmental obstructions (walls, workout equipment, etc.) between the app and your heart rate monitor(s) and the Bluetooth capabilities of your phone or tablet.

Obstructions

In a gym with a high number of obstructions we've seen a max distance of 30-50'. However, there are a number of steps you can take to make sure you achieve the highest distance.

The most important is to make sure there is an unobstructed line-of-sight from your phone/tablet to each heart rate monitor.

Compared to Other Apps

If you're coming from another heart rate monitoring app you should see the same range you saw in other apps (all apps communicate with the monitors in a similiar manner).

Support

If you're having any issues related to range send us an email. We can help diagnose any issues and get you setup with a possible software-based solution.

How do I register my gym members?

You can register your clients from a single phone/tablet (owned by your gym) or have your clients sign up on their own devices.

Learn more
Can the app detect nearby gym members?

Yes! You can change this behavior in the workout setting screen if you prefer to manually add profiles.



Can I automatically remove inactive profiles from the workout?

Yes! You can change this behavior in the workout setting screen if you prefer to manually remove profiles.

How many gym members can workout at-once?

The maximum number of heart rate monitors that can be connected depends on the Bluetooth capabilities of your phone or tablet.

We have had gyms run workouts with 25+ monitors at the same time.

If you're unsure about the Bluetooth capabilities of your device request a demo and we'll give you a free trial so you can make sure Heart Rate Ninja works for your needs.

If you need to show more gym member on the screen you can use our Boost Mode feature! Boost Mode lets you run Heart Rate Ninja on additional devices support more Bluetooth connections than one device alone.

Can I display the app on a TV or projector? Yes! The specifics will depend on what device you're using, but it is supported on most devices.

Using a cable

  1. Connect your phone or tablet to your TV via an HDMI cable.
  2. Heart Rate Ninja will automatically detect your TV

The required cable depends on your specific phone or tablet. Searching the web for 'YOUR DEVICE to HDMI' should return an appropriate cable. Most iOS devices will use a Lighting-to-HDMI cable.

Make sure your HDMI cable supports both Mirror and Extended Modes in-order to use Trainer View.

Send us an email if you need help picking a cable. hello@heartrateninja.com

Do I need a subscription for each gym location?

Yes. If your gym has multiple locations you will need a subscription for each location. If you have any questions you can contact us and we'll help figure out which subscription will work best for your gym.

Can I try the app at my gym for free?

Yes. Request a free demo and we'll set you started with a free trial! Request free demo

What happens if I exceed the profile limit?

You will be prompted to upgrade to the next subscription tier. We will show you a reminder when you start to get close to the limit.

You can also remove any inactive profiles from your gym to try to stay under the limit. Profiles do not have to be deleted in order to be removed from your gym, they only need to remove your invite code from their profile. These profiles will still exist and can rejoin your gym at a later time if they become active again by re-entering your invite code.

Can I downgrade my subscription?

Yes. You can upgrade or downgrade your subscription based on how many profiles you need by opening the gym upgrades screen and selecting your desired subscription (so long as that subscription's profile limit is not less than your number of profiles).

If you exceed your subscription's profile limit you will be prompted to upgrade to the next subscription tier.
