I see many companies releasing heart rate monitors so I guess these are very popular these days, while there are also Bluetooth-powered versions working with phone applications and this is the type I’m interested in. Sports Tracker introduced its Bluetooth Heart Rate Monitor working with the free applications on Android and Symbian phones.
The little gadget coming in a nice shape can help user track heart rate data in real time for performance analysis. It shows current, average and maximum heart rate details, zones, heart rate charts and distribution. The device powers via USB and comes with a quality textile strap.
You can pre-order it from Sports Tracker for 59.90 EUR.
