MyZones calculates training heart rate zones that can be used by runners, cyclists, triathletes from keen fitness enthusiasts to focussed racers.

Unlike one-fits-all formulas MyZones can calculate your personal zones from maximum heart rate, race HR data, or professional lab test results.

MyZones provides explanations of each training zone and the different methods you can use to calculate them.

The training zones calculated can be used to set your heart rate monitor (e.g. Polar, Garmin or Suunto). It also allows you to enter the zones into training diaries such as iSMARTtrain.

The accuracy and experience loaded into MyZones means you get to train and race with better results.

All it does is calculate your training zones from whatever base metric you enter. A calculator can do that. I was hoping for more...especially for the price $$$.

I expected something quite interesting for the money this app costs. I have an excel spreadsheet that I put together in 20 minutes that is much more comprehensive than this. Not even worth downloading if it was free.
