But isn't Fitbit's fitness app better than Apple Health? I have an S3 and it's always telling me to close my rings and breathe for a minute, but in terms of actual exercise I feel like Fitbit did a much better job of it a couple of years ago than Apple currently does. I say a couple of years ago because that's how long I've been using an Apple Watch.
I ended up going with a nice looking, Nokia Steel HR as a proof of concept for myself. Just had to actual try it because to me at least it wasn't clear how integration actually would work.
It was on sale (less than half the price of an Apple Watch 3) and doesn't look like a Smart Watch really - but I'm completely addicted now and get why a lot of reviewers said they were sold on the Apple Watch after a day of wearing it - so am just considering buying an Apple Watch in addition to this now (I would just return this but I like the option of having a more 'classic' looking watch for certain occasions).
The Nokia 'plays nice' with Apple Health - so the data can be shared back and forth quite easily in Apple Health. Its tracking my steps, calories, exercise, HR, distance, sleep etc and I can view in Apple Health or the Nokia/Withings app. But now that I'm like fascinated with the idea of a smart watch I'm leaning towards getting the Apple one for the full integration. There are things Apple Watch seems to track (I really like the 'standing' tracking that Apple Watch seems to have) that I wish this thing could do. I really want to get those damn rings but think I need Apple Watch for that (i can set goals, progress, unlock achievements with Nokia but never as satisfying as Apple's look lol)
REGARDING FITBIT - I've heard the same - that partially due to Fitbit doing it longer than Apple and kind of making this their hill to die on - they have some more accurate fitness related metrics and tracking.
However I do like the idea of integration with Apple Health since unlike Nokia/Withings and Fitbit - I know I'll keep using Apple hardware/Apple Health well into the future - so I want the data all in there as easy as possible. I think for Fitbit you need a third party syncing app (unlike this Nokia which directly links up with Apple Health). I'm not a hardcore fitness enthusiast so the difference between Apple and Fitbit exercise tracking likely not a deal breaker.
You may know all of this already but just thought I'd give my insights to anyone else who may be interest as well - since I spent many hours trying to understand this all lately and found best way to understand was to buy something.
Things I learned:
1) Once you get a 'smart' watch - you'll probably get addicted.
2) If you're going to spend more than $150 on it, just save yourself the hassle and go with an Apple one so you don't need any other apps / logins.
