VPower - GPS cycling computer with Virtual Power Meter, Strava upload and ride tracker

**HALF PRICE DISCOUNT** VPower is the first accurate Virtual Power meter for iPhone, why spend hundreds of dollars on a physical power meter when VPower can calculate and record your power in real time for a fraction of the cost. VPower stores all your ride data which you can then upload to Strava or other training tools. VPower is the best cycle computer, with the best interface whatever your cycling level.

Either mount your phone on you handlebars with a bike mount for live readings or record your ride with your phone in your jersey pocket to analyse your power data after your ride. Strava premium users will get complete power analysis such as power curves and power zone breakdowns.

VPower is the culmination of 6 months intensive testing and development. Power has been tested against physical power meters such a Stages and found to have only 10%-15% average difference.

VPower works by calculating the four forces that your power is used to overcome to give your total power output. These are gravity, air resistance, road resistance and acceleration, the power detail screen shows these values in real time.

VPower gets wind and weather conditions in you location from a live weather feed, an internet connection is required to access this. If no internet connection is available default values will be used.

Features include:

* Power (with different levels of smoothing)
* Average Power
* Maximum Power
* Power in Watts/kg
* Power Zones (based onFunctional Threshold Power)
* Dynamic map to view your location and route you have taken
* Speed (Average and Maximum)
* Acceleration
* Distance travelled
* Altitude
* Rate of Accent (VAM)
* Total ascent and descent
* Hill grade
* Max hill grade
* Air Temperature
* Apparent wind speed
* Share ride data by email or on Strava

VPower is only as accurate as the phones sensors, a good GPS signal is required, built up areas can give errors in position which may cause spikes in the readings. Extensive smoothing algorithms have been used to reduce these.

Please do give feedback in the contact screen if you have any suggestions or issues.

*** Please note :
Continued use of GPS running in the background can dramatically decrease battery life.
