A:AnswerFrom Apple.com: "Apple Watch Series 7 has a water resistance rating of 50 meters under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch Series 7 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. Stainless steel and leather bands are not water resistant."
A:AnswerNot sure if it will connect with android phones. Probably it is recommended against people with afib is that the ECG detects afib experience and it might alert your contact person
A:AnswerAnyone can benefit from the watch. I'm not a fitness person either, but I find that I have become more active with the reminders and encouragement from the Activity app. Plus I am in a Heartline study where I get a watch for around $50. This is for people over 60, I'm glad I started being more active and it really isn't an extreme amount of moving around to be successful.
