The Apple Watch has finally been approved to collect ECG readings in Australia, but in the years since that feature debuted internationally the market has filled with devices ready and waiting to give you information about your heart.

Unlike some other health metrics collected by gadgets like smartwatches and scales, which are more there for entertainment and general information purposes, a lot of the data collected on your heart has the potential to be diagnostically relevant.
