Streaky connection

A Herfrequenzmesser, the sounds recording data on the smartphone so once in handy. Advertising for this model with Runtastic Pro (Android and Apple). This application is even free of charge when purchasing the PM250. It is characterized by the Bluetooth data (heart rate progress is shown by diagram) and in addition, the GPS data. Thus, not only heart rate, exercise time and calorie consumption is recorded, but also how fast it was traveling and how much distance you have covered.
The results can be uploaded to the runtastic account. Thus can each training session with the other comparisons.

The technique in practice:
In the heart rate monitor already sits a button battery. There is no on / off switch for Bluetooth or energy. Per Samsung Galaxy S3 connect through Runtastic Pro succeeded well. The connection takes a few seconds. Sometimes there is no connection, and the application should then be stopped and restarted again. Then it works.
There were problems with the LG P710. There really could not be established.
The heart rates were detected in three out of four participants. Two of them were overweight. If the overweight no signal has been detected. Positives: The Gurtdurchmesser was enough for all participants without triggering oppressive feelings.

Small skin reaction:
In one of the four participants, there were two hours wearing time, at the point at which there was the PM250, a small skin reaction that felt like a mild sunburn.

Application:
Except Runtastic Pro, there could be even more applications for Android or iOS, which could use the PM250. In addition, there are unfortunately no information.

Privacy:
Whether to provide its data via Runtastic Pro showcased or this rather prevents, should be considered thoroughly. Uploading of data is not a must.

Conclusion:
Unfortunately not reliably compatible with all Android smartphones and unfortunately too little information about other applications that might use this model. If the connection is, there are no crashes and the data is reliably recorded.
