Can not believe apple allow this app on the store for £4. Complete waste and useless ### 1/5 — A rip off *2011-09-20, version 1.0.1* An app that loads in 20 seconds and is rip off of some free calculations that are public domain is just a rip off. Expecting value add and got a sour taste in my mouth Shame on you! ### 1/5 — Useless *2011-01-13, version 1.0.1* 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. ### 1/5 — Doesn't work *2010-10-13, version 0* Useless ### 1/5 — Lame *2010-09-23, version 0* 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 $$$. ### 1/5 — Doesn't work with iOS 4.X *2010-09-09, version 0* Save your cash ### 2/5 — Pricey *2010-08-23, version 0* Bit pricey for what you get ### 5/5 — Myzone *2010-05-20, version 0* This is an essential piece of kit for anyone who is serious about their training and were time to train is tight. Pop this on your iPhone plug in some music and sweat away. Quick and easy ### 5/5 — myzones *2010-04-23, version 0* The fact is that most people DONT know their zones and most people CANNOT work them out is the reason behind MZ. MZ's zones are actually personalised because you can use whichever of the five possible metrics you decide, and not have to use one of those really bad HR zones wall charts in a gym. The zones are also fully explained to ensure the correct mixture of training, another piece of expertise loaded into the App which self coached athletes routinely get wrong. Sadly most know zone names or throw phrases about but they do not know what to do with them - MZ helps athletes with this difficult task. ### 5/5 — Brilliant app! *2010-04-21, version 0* I found this app really easy to use, just needed to type in my max heart rate and it calculated all the heart rate zones for me instantly in a simple to read display. To make it even better it goes into detail describing the different levels within the heart rate zones saying what it is and the effects of training at each level. In my opinion it's an app that's definately worth having plus it's made my turbo sessions a bit more interesting. ## Frequently asked questions about MyZones ### What is MyZones used for?
