  • How do I get the charger port rubber plugs that should have come with my X2 to make it water proof so I can swim with it on?

    Is the black strap water proof that came with the X2?

    • Thank you for your query! I’d like to clarify that your X2 device does not require a rubber plug for waterproofing; it can be used underwater without them. Additionally, the black strap that came with the X2 is also waterproof.

  • How do I link Fontier X app information to my Strava app? I want to share data?

  • Is there a setting to track resting activities such as sleep and meditation?

  • Is it possible to use Garmin or Polar HRM straps with X2? Would doing so affect performance in any way (including positive)?

    • Thank you for your question!

      Our device has been specifically tested with our own chest straps. While other straps, like those from Garmin or Polar, may fit and provide accurate data, we cannot guarantee their performance with the X2.

      If you choose to try them, please monitor the results closely to ensure they meet your expectations.

  • I am new to FFx2 and so far liking the all the features. Even my cardiologist, last Thursday, said it’s good to keep my training intensity in check after a cardiac ablation for AFib. My question is, how can I see the graphs or data from the display while using the FFx2?
