Before I start, I know this subject has been brought up already but about 2 years ago but advances in technology may change the answer.

I'm looking to get a HRM for my Runner 3.

I use Strava, Zwift, Training peaks and also use Tacx when i'm on my Turbo Trainer.

I would like to know which HRM is compatible with all of these please.

    Most BT LE devices should work, but some work better than others. Price seems to not be a factor as the cheaper ones often seem to work better than the expensive ones. This is due to the fact that cheap models are more likely to use the base BT protocols and not customize them for advanced features or settings like more expensive models do (and there is no way of knowing if a manufacturer has tweaked the protocols to take them out of compliance). The BT standard is in such a way a 'standard' that it can be widely interpreted with different settings for buffer sizes, time outs, profiles, protocols, antenna configurations, etc.. TomTom cannot change their code every time a manufacturers messes with the BT coding. This is a case where paying more will not increase the chances of connectivity, it may actually decrease it. There are thousands of models out there so there is no way for TT to test them all and since the manufacturers often tweak the BT settings there is no way to know upfront if a pair will work or not.

    In nay case, you will not find an HR strap that works with all these things at once. BT+ is a one-to-one relationship so the HR strap will only be able to sync with one device, either the watch or a phone or tablet (for Zwift).

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
