GPS Speedometer and Odometer is an iPhone app developed by Nikhil Kumar that helps you measure the speed and distance of your car, bike, walk, run, boat, bus, train, bicycle, and even airplane. This travel and navigation app is available for free and has a lot of features that make it stand out from other similar apps.

The app shows you the current speed, average speed, moving speed, maximum speed, distance, odometer, stopwatch, clock, movement time, idle time, pause time, latitude, longitude, altitude, GPS connectivity, and direction of movement. The speed accuracy is close to 99%, and it can even work offline. With 5 portrait and 5 landscape modes, including HUD (Head-up Display), you can customize the display to fit your preferences.

One of the most useful features of this app is the ability to set both the minimum and maximum speed limits, ensuring you don't go too fast. If you exceed the limit, the app starts vibrating, sounding, and changes the display color to red. You can also set 5 different speed limits at the same time and view all statistics with a tap. The app tracks your route on the map and keeps track of every detail, including speed, accuracy, altitude, latitude, and longitude.
