Heart Rate Zones (colors)?

Colors represent Heart Rate Zones as follows:

  • Grey: Bellow 60%
  • Blue: 61-70%
  • Green: 71-80% green
  • Orange: 81-90% orange
  • Red: 91+ red

The rings' colors represent time spent in each zone and are ordered clockwise. 

The zone you spend the most time in is the one that starts at the 12-hour mark.   
While working out, your current zone will be displayed thicker (bold).

Can I customize my HR zones? 

Not yet, but we will add that option to the app soon. 

Can I see the HR average instead of the final HR when the interval ends? 

Not yet, but we will add that option to the app soon. 

Displaying HR% instead of BPM

ErgZone will only display BPM when a Max Heart Rate is not provided.

Updating Max Heart Rate:

  1. On the ErgZone app
  2. Go to "Settings" (gear icon on the top left of the ErgZone app)
  3. Scroll to the Heart Rate section and provide your MAX Heart Rate.

Note: Your HR% will be calculated considering the Heart Rate Reserve formula if you set Resting Heart Rate.

If you see HR% during your workouts, you have set Max Heart Rate on the app. 

Displaying HR instead of HR%

If you set MAX Heart Rate on Settings, ErgZone will display HR% instead of BPM. 

To make sure BPM is displayed, ensure MX Heart Rate is empty. 

Updating Max Heart Rate:

  1. On the ErgZone app
  2. Go to "Settings" (gear icon on the top left of the ErgZone app)
  3. Scroll to the Heart Rate section and provide your MAX Heart Rate.

Projected Finish Time(*)

Projected finish time is available for workouts where all intervals/splits are for distance (meters). 

Press the “Time” column twice during the workout to see it.

The projected time displayed in the summary line (1st line) is the  total projected time
ErgZone also calculates the projected time  for each split, which is something the PM5 doesn’t show.
Projected Time display decimals (not available on the PM5) to give athletes more precision. 
This is a powerful tool for Time Trials, Ranking Pieces, Races, during Competitions, and remote coaching.
