We'd like to update or refresh current version of the icon we are using for our iOS application: Speed Tracker. GPS Speedometer and Trip Computer. The app has already spent in App Store the whole year and the icon hasn't changed since the first day. We are updating the app on monthly basis by adding new features and improving the look but hasn't done anything with the icon itself. Now we'd like to see something fresh and new.
The app itself is the combination of GPS speedometer and Trip computer in one place. The main goal is to follow and save all your trips with all the corresponding data, like speed, time, distance, heading and etc, basing on the GPS signal and Google maps. The application has 3 unique "skins" or "modes" inside. 2 for portrait mode and one for landscape (now being approved by Apple).
Some requirements we have are:
1. Letters GPS on the icon
2. The icon should be related to the word speed or speedometer.
