Garmin
Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I still have to first generation versa. It still runs great to this day 6 years later. It’s a shame what has happened to Fitbit over the years
I bought a Sense a few years but the screen cracked so I bought Versa (2maybe?) and the battery completely broke and now I'm back to my original Sense! Cracked but still works well! I've been wanting a new fitness tracker, and while I have been using Fitbit for many years, I've been so disappointed but I just don't know what else I would be happy with.
Charge 6 might still be on sale for 100. Never really used the Smartphone functions on my versa, liking the charge so far Charge does have healthconnect, which is a standard for apps and other devices to share health stuff. I don't know if that works with apple.
Damn. I had no idea they that bad. I used a Fitbit verse for years and it would last like a week even with rides and such.
My seventh Fitbit died last week (from Luxe to Versa to Charge 5 and 6, this was my second in-warranty replacement), white line on the screen to no screen at all within 24 hours. So with some Target credit I decided to go with a Garmin Instinct for $200. The GPS is much, much more accurate (even when not paired with my phone), the app tracks a lot more information than the Fitbit app did and takes up a third of the space on my phone. I miss the constant step updates; the Garmin just updates every minute. That's about the only drawback.
The Versas do all that and more and the battery life is 5-7 days.
