RealtimeSpeedmeter 4+

This app is a new speedometer app that aims at more accurate and real-time speed measurement than other speedometer apps by using the values of the iPhone's built-in GPS and accelerometer.

feature:
- [Real-time speed display] Uses a combination of GPS and acceleration sensor values to display more accurate speed in real time
- [Can be measured even in places where GPS cannot be received] Since the speed is measured based on the acceleration sensor, it is possible to reflect changes in speed even in places where GPS cannot be used, such as indoors and tunnels.
- [Easy-to-understand speed notation] Speed is indicated by both analog meter and digital display
- [Customize] You can select the fastest speed setting and speed unit from the settings
