A topic that frustrates me due to not being able to find a good solution! My only concern was time asleep and I never pondered stage accuracy.
- Garmin, I’ve tried two straps (vivosport & vivosmart 4). They both count sitting around before bed as sleeping even when I put it on 2 hours before sleep as recommended. It’d also count my coffee time as sleep most mornings. Neither catch an occasional nap. Upside is the data is highly portable
- Whoop worked great and agreed with my sense of when I slept. Bad thing of the data Is locked up in their ecosystem. I’d rather have it out in health or TrainingPeaks. Advice was always non useful too, it just told me to sleep 11 hours per day. As if.
- Tried a go2sleep briefly but wasn’t confident in their proprietary, never-verified algorithms. Seemed roughly as accurate as the Garmin but I didn’t use it long
- Ordered an Oura last September but canceled during the long wait when I’d heard the update was imminent. Then they went subscription, and though it’s small, that entire sequence of events frustrated me enough I didn’t bother reordering
- Ordered another whoop after that but again canceled because I don’t like subscriptions and data being locked up outside my usual apps so this whole topic has me stumped and still don’t have a tracker.
For what it’s worth, the fitnesssyncer app links with a lot of sleep tracker companies including Fitbit, Garmin, oura, withings, and a bunch of others.
