Witch watch from Huawei to choose

I’m here to search for the best option for health and that can be pairing with an iPhone ! Last months I have had some not good news high blood pressure and now seems my heart as some timing problem that I need to solve with doctors ! That said I’m looking for a what that can see my heart rating and blood pressure so I can get an overall view of my health ! I saw some gen 5 in the site that were on promo like 100 or so less by Huawei but went there and I think I missed the promo cause I don’t see it in the mane page like it was before so I’m confuse now cause that one seemed to had all the main characteristics I need ! I do hope after I get all done to do workout ! But for now it’s time to stop and monitoring me ! Thanks !
