You will need an active GPS connection for the app work.
It is a simple speedguage app which uses GPS system.
You can use this app with bike smartphone holder and anything else.
It shows you total distance(mileage), current distance, max and current speed.
And speed limit alert function added.
Kilometers(km/h, kph) as well as miles(mi/h, mph) are supported in this application.
NOTE: Due to phone GPS limitation, Speedview may not work well in cloudy weather or indoor places.
And I don't guarantee that it shows accurate data because of GPS errors.
