Device Support

Does Flex Support my Apple Watch?

The Apple Watch can be used as a real-time heart rate wearable and rep tracker. So sign up, what are you waiting for!

Does Flex Support my Fitbit?

Unfortunatly Fitbit's cannot be used to collected real-time heart rate and rep data. Fitbit's are designed to be worn throughout the day and, as such, only transmit data periodically to preserve battery life.

What are all the devices Flex supports?

  • Apple Watch Series 1,2,3 & Sport

  • Android Wear

  • Samsung Gear

  • Pebble Watch (yes they still exist)

If your wearable device is not in this list, don't worry, it could still be supported if it supports realtime data transmission. This is just a list of known wearables.
