BoatSpeed provides a simple display of speed and heading.
* It also shows lattitude, longitude, max speed and current time.
* Every effort has been made to optimise speed reporting at low speeds (<10 knots), when there can be many seconds between changes in reported location from the inbuilt GPS.
* Background colour can be toggled between daytime (black on yellow) and night time (black on red). Tap on “Day or Night” to change it.
* Background colour is initially set based on current time and last known location.
* Tap on the “Units” to rotate through KN, MPH and KPH.
* Max speed is displayed in current units. Tap on the max speed to reset it to zero.
* Boatspeed requires IOS 8 and a minimum iPhone 4S.
