- FitBit familiarity. Having used a FitBit for a few months there was no getting used to a new app and its navigation.
- Fairly simple to use, especially during workouts.
- Screens are "sticky" meaning they don't change back to a home screen after a period of time. Some have said they don't like that. I like it.
- Step count isn't consistent with other FitBit devices (comparing past workouts with a previous device). I would like to test and experiment with this but I don't know that I want to invest the time. I wear both the ChargeHR and my One, and the ChargeHR is consistently under the One in steps, with the One matching my Omron. The 11-year old tried wearing both a Zip and his Charge and they were pretty consistent.
- Driving home the other day I could tell it was counting steps while I was driving. Not a crazy number of steps added but up to 100
- The charging connection is very poor. Why they didn't just use micro-USB instead of a proprietary connector, that doesn't even make a good positive connection, is beyond me
- Can't be sure how responsive the heart rate monitor is. This is mainly a concern on the spin cycle as I watch that metric regularly. It's not a big deal on most other exercises. It seems to take a while for the monitor to catch up to the heart rate. I don't think chest strap monitors have the same issue.
