Finally, a new version (4.0.0) of the app is available on the Google Play Store. Since last year, a lot of features has been added (see here for all of them). First, the Windmeter, the cheaper anemometer (~60$) from WeatherFlow may now record air speed. It doesn't record temperature, humidity and pressure as the WeatherMeter device though (~90$). Second, the BlueFly vario may also be connected (some personal notes about it here): the interest for CdaCrr is mainly, for the moment, to provide a very precise barometer (+/-10cm) to compare for instance virtual elevations and real ones to validate the Cda and Crr estimations or to detect some oddities. So, currently, the app may records data from 5 sensors (power, speed, heart rate, air speed, barometer) and sometimes the app suffers unhappily from disconnections between the phone and its sensors. At last, the app is based more and more on BLE protocol (device detection has been improved, see there) and ANT+ will be less and less supported.
