Fitbit Charge 6
A Fitbit Charge 6 for sleep and health tracking.
I use the Fitbit Charge 6, because it runs for around ~5 days without charging in my experience. With the insights into how many steps and how much sleep I am getting, plus other health insights, I like how I am able to track my health.
Now I am no Bryan Johnson, but one big goal of mine was to be able to take care of myself better, and to automate some ways to do so.
One of them was to be able to get a more stable sleeping schedule, which tracking helps take care of.
I used to use a Xiaomi band, but the software became quickly deprecated, and it was not really giving as good insights as the current Fitbit. In some ways, you need a continuing benefit to help “take care of the equipment that takes care of you”.
