Speed and Altitude Camera is a handy utility for any android device, which allows you to add the speed and altitude of your current location to your photos. It’s very easy to use and simply works.
The speed and altitude of your location can be expressed in different units, such as meters per second and meters above sea level.
The app allows you to use the built-in camera to capture an image, which will then be displayed on your device’s screen. You will see changes in the side panel’s color as you change your speed.
