ZoneTrainer enables those seeking cardiovascular fitness to train within a customized target zone. Feedback is provided by vibration when changing to and from custom heart rate zones. This is by far the most requested feature for the Fitbit Ionic.

NOTE: If a CUSTOM HEART RATE is not set on your phone’s Fitbit app, vibrations occur upon changes from all zones and the CARDIO zone is used for calculating LowHR, HighHR, Low%, and High%.


• Use haptic feedback when the user enters a new heart rate zone.

• The display includes sixteen key training indicators in addition to the current Battery state and the actual Time.


The following permissions are needed for this app to function:

• Activity

• User Profile

• Heart Rate

• Location
