1. The Bicycle Power Meter provides the most accurate power, energy, and % grade measurements in addition to typical cycle computer functions (elevation, speed, cadence (see below notes), mapping, logging, and charting with no external sensors, hardware or calibration required). The Bicycle Power Meter provides these features at a tiny fraction of the cost of conventional power meters and with no monthly subscription fee. The app is also compatible with the Zephyr Bluetooth HxM Heart Rate Monitor and (beta) ANT+TM compatible heart rate, speed and cadence sensors1. Try the app with no risk: we will provide support to help get the app to run to your satisfaction or a refund will be issued.

2. The best available smartphone resources (GPS, barometer pressure sensor, accelerometers, weather & elevation services, etc.) are used to achieve the best accuracy.

3. % braking energy can be viewed (user option) to give insight into how hard you brake into a turn.

4. Routes are plotted and graphed in the app, in real time with option for audio speech.

5. Route paths are color scaled in real time based on the users preference. One click changes the scale: power, speed, elevation, % grade, cadence or heart rate (with Bluetooth HRM) to map where on the ride significant events occurred.

6. A screenshot of the statistical data with the color coded map along with the raw data files (.csv .gpx and .tcx formats) can be easily emailed. .tcx format includes key parameters (speed, power, elevation, cadence, heart rate, etc.) to allow uploading to other analysis programs such as Garmin Connect, Training Peaks, Strava, Golden Cheetah, Google Earth, etc.

7. The accuracy of the power meter has been tested against state of the art, major brand named power meters.

8. Without calibration (only entering rider's weight and choosing bicycle type), average power for a given ride typically correlates to within 15% (with no drafting) of a conventional power meter.

9. Wind speed and direction effects are included! (with internet connection using local weather information, drafting effects not included).

10. Several default bicycle types are available to choose from, or bicycle weights and coefficients can be customized.

11. The app will run in the background.

12. English and Metric Units available. Set in user preference menu. English, German, Spanish, French language support.

13. Reload ride data to show progress and compare rides.

CADENCE TIPS:
***NOTE*** For some phones when the screen is turned off, the phone's accelerometers are disabled and the cadence data may be unavailable. This limitation has been documented in a number of other apps including pedometers. Using the screen lock feature can bypass this.
* For best results, prior to riding, under menu>preferences, select the phone's handlebar mounting orientation (portrait or landscape). If carrying in a jersey back pocket, set relative to the phone's orientation compared to looking forward at the handlebars.
* The cadence RPM and averages are tuned to power strokes detected from the phone's low power accelerometers while moving (i.e. not back-pedaling, downhill/coasting, etc.) and is more accurate as the power output increases above 1W/kg.
* The cadence sensitivity can be adjusted under menu>preferences. The default 'nominal' setting has so far produced the best sensitivity while minimizing spurious high readings.
* Noise may be observed in instantaneous readings depending on riding conditions (such as rough or off-road), riding styles, rider's power to weight ratio, and phone hardware.

    This app exceeds my expectations. A complete bike computer! I compare it to my Cateye and it is very accurate. I love the power feature as well. This app would be a perfect 5 stars if it offered Google Drive integration so that you could save the files to your Google Drive instead of e-mailing them to yourself. I would also like to see the UI cleaned up by making it more consistent with the curren

    At £4.99 I thought it was worth a punt and really glad I did. One of the main reasons for the app was live gradient tracking Which is excellent throughout a ride. Then there are the other Metrics which are superb. In fact what surprised me most was the cadence - I don't have it linked to a sensor but have a separate bike comp with sensor and they both map incredibly closely. One suggestion would

    I installed on both a Galaxy S5 and Galaxy S4 and no Ant+ devices were found. I tried five different HR monitors and two Cadence/Power sensors and none could be found; and this is with the paid version. Then I tried four other Apps and all of them found my Ant+ devices.

    My only concern is the close proximity of the "pause" and "clear " buttons. If wanting to hastily pause the program it might result in clearing the data. Could the buttons be spaced or relocated?

    Way better than the cost of a power meter or powertap add-on.
