Profile and Heart Rate

Your profile, under Settings → Profile, holds your name, the numbers FitKeep uses to work out your heart rate zones, and how dates and numbers are shown. Heart rate zones show how hard you worked during an activity: FitKeep breaks every activity down by zone so you can see how much time you spent at each intensity.

Your profile

  • Email address: the address you sign in with. It can’t be changed
  • Display name: the name FitKeep uses for you
  • Birth date and Max heart rate (bpm): used for your heart rate zones. See Set your max heart rate
  • Number and date format: how numbers, dates and times are shown, such as the decimal separator and the order of day and month. Auto-detect from browser follows your browser’s language
  • Timezone: detected from your browser and updated when it changes. FitKeep uses it for what depends on your local day, such as when your connected services are checked at night. If you train with a Training Plan, its weeks run Monday to Sunday in this timezone

Select Update profile to save. Below it you can set or change the password you sign in with by email.

Set your max heart rate

Zones are calculated from your maximum heart rate, so setting it makes your zones accurate:

  1. Open Settings → Profile
  2. Enter your known max heart rate in bpm, or leave it empty
  3. If you leave it empty, FitKeep estimates it from your birth date
  4. Select Update profile

Not sure what your max heart rate is? The estimate from your age is a reasonable starting point. If you’ve seen a higher number in a hard effort or a lab test, enter that instead for a better fit.

The Tanaka formula

Without a max heart rate of your own, FitKeep estimates it from your age with the Tanaka formula: 207 − (0.7 × age). At 40 that gives 179 bpm. It fits most adults better than the older “220 minus age” rule, but people of the same age can differ by 10 bpm or more, so a measured value is better.

Without a birth date either, FitKeep uses 185 bpm, and the heart rate zones on your activities suggest setting your birth date.

The five zones

FitKeep uses the industry-standard 5-zone model, calculated as a percentage of your max heart rate:

  • Zone 1, Very light (50–60%): recovery and warm-up
  • Zone 2, Light (60–70%): easy aerobic base building
  • Zone 3, Moderate (70–80%): steady tempo effort
  • Zone 4, Hard (80–90%): threshold and harder intervals
  • Zone 5, Maximum (90%+): all-out efforts, uncapped at the top

Where to view your zones

Open any activity’s detail page to see its heart rate zone breakdown, including the time and percentage you spent in each zone. Updating your max heart rate updates the zones across all of your activities. Change next to the max heart rate there takes you to your profile.
