Hi!
I’m using Apple Watch as HR sensor and with my iPhone it workd just fine with TrainerDay. Sometimes I would like to use an older iPad Air 2 with Trainerday, but havent got my Watch to work as HR sensor in that setup.
Do you know if it is supported, or should I get a newer iPad with latest OS.
I think your device has to have Apple Health on it and you need to enable the permissions in apple health. Many older devices don’t support Apple health.
