I've just bought a Vivoactive 4s and created a HIIT workout - 5 exercises x 5 (35 sec work & 25 see rest). When I try to send it to my iPhone it tells me that my device is incompatible.
I just want my phone to vibrate when a work/rest period starts and tell me which exercise I should be doing. Is there something I'm missing in the way I'm setting this up.
Thanks in advance.
