Bike CdaCrr Details
Bike computer to improve your bike racing position and select better equipment, by measuring CdA (drag*area) and Crr (rolling resistance) coefficients. It requires a phone with built-in ANT+ support and ANT+ sensors for power and speed. PowerTap, Power2Max, Quark, and SRM powermeters (plus ANT+ speed sensor for the last ones) are currently supported. Read the help to quickly see how to use it: http://cdacrr.blogspot.fr/p/help.html For support, send mail at bikecdacrr@gmail.com Current features: -Classic lap mode (default, click each lap) where it is possible to: -Measure Crr on ridden laps at slow speed (<15kmh) -Measure CdA on ridden laps at high speed (>30kmh) -Model uses air density accurately computed with weather station data and detected sensors -Possible to hear/record voice message each lap -Several CSV files are stored on the device and can be sent by mail (one for the ride, one for the laps/segments) -Possible to activate cloud storage to list/edit previous runs later -Possible to plot virtual vs real elevation (barometer needed) -Configurable field to switch between different fields (altitude, cadence, bike direction,...) -Averaging power on a lap or smoothing it over a duration -Measure road vibration with phone accelerometer -ANT+ devices Id are stored and searched preferably Several checks are done to discard some laps because of bad data: -Detect data drops (ANT+ events not received) -Detect zero cadence from a crank based PM -Detect ANT+ sensor battery status This version is free, but additional features are possible by switching to the premium version: Premium features: -Defined lap length mode (for velodrome, click once to start the run) + two wind models (beta) -Automatic segment mode (needs barometer) to record CdA during a ride (given periodically with 2 digits) which starts each time the minimal speed is reached -Support Garmin tempe sensor to record local temperature -Possible to use Bluetooth headset to hear/record voice messages Download the key for the premium version here Known bugs: ...What's new in Bike CdaCrr 1.5.0
New in 1.5.0 -ANT+ heart rate -Sending/deleting CSV files is easier -Weather station location detected with GPS -Option to change the minimal speed for CdA -In automatic segment mode, runs are not ended anymore with a bike stop (only with a user long click) -Android 7.0 supported -Time trial start is based on power now (speed before) -Data is recorded in the cloud each lap now (each run before) -Add the possibility to search again one or more ANT+ device -Fix weird altitude change during rideDownload Bike CdaCrr 1.5.0 APK
