Zone 2 app tracks how much of your weekly workout time is performed in the zone 2 heart rate range, typically between 60-70% of your maximum heart rate.

The optimal number of minutes to spend in zone 2 per week can vary based on individual fitness levels.

From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
