For Fitbit · Built on the Google Health API
Know your baseline.
Klair reads the health data your watch already collects and turns it into daily trends and honest deltas against your own baseline. Connect your Google account and see where you actually stand.
Free to start. No card required.
The signals
Four numbers, each measured against you.
Klair doesn't score you against a generic goal. Every metric is compared with your own rolling average, so the only person you're up against is last month's you.
Steps
Daily totals with a rolling average, so a slow week shows up before it becomes a slow month.
Resting heart rate
The quietest number your body reports, and the most honest one about recovery and stress.
Heart rate
Your daily average, tracked across weeks so slow drift stands out from normal noise.
Active zone minutes
Time spent where effort actually counts, summed per day and weighed against your habit.
How it works
Two minutes from sign-in to insight.
Connect
