in use with RuntasticPRO App and Nexus 7 (Android)

You have to make sure that before pairing easy to moisturize the body hugging contacts, otherwise the belt can not be found. After pairing RuntasticPRO accepted the harness easily.

The values ​​calculated tune the belt also (with a digital sphygmomanometer measured it).

One point deduction is available for the installed battery. The CR2025 provides only about 170 mAh, while the CR2032 also frequently used (which I still have that even in Reserver, is often used in computer motherboards, remote controls), after all, creates up to 230 mAh and is only slightly thicker. Pricewise, the two batteries apart barely.
The ideal would be of course a replaceable battery with the ability to load via miniUSB.
