When I bought a macbook in december last year, I surfed to the Polar website to download the mac-version of Polar Personal Trainer that I had been using to manage my training data on my Windows PC before. But as you probably know I couldn’t find anything. I started to search for third party software but there wasn’t anything that was cheap and easy to use. What I found was some open-source C-code that decoded the audio-stream generated by the Polar watches that support SonicLink. That’s why I started to build pulse-o-meter. 3 months later I bought an iPhone and, of course, I want to have my data on the iPhone, too! That’s how I started to build the iPhone-client. Both, the OS X version and the iPhone version are not finished, but they have all the basic features and I already use them to mange my training-data. If you want to test a trial version of pulse-o-meter yourself, just contact me!
