Pocket Speed Gun, Free

Encontre a velocidade de qualquer coisa!

Find the speed of anything! This app is a tool you can use to find the speed of any object, as long as you have reference points you know the distance between. There are two modes (three in the paid version); each one takes more effort to use but increases accuracy:

* Live: In Live mode, you simply use the app as a stopwatch. Enter the distance traveled during that time, and it tells you the speed. This mode is great for quick estimates when exact timing is not crucial, such as a foot race, or a full lap of a car race.

* Two Frame: The principle here is the same as in Live mode, but instead you record a video of the moving object. Step through the frames of the video to tell the app exactly when it crossed the start and end points. This mode allows you to take more accurate readings of faster objects.

* Six Point: This mode is only available in the paid version (not this free version). It allows you to measure high speed objects more accurately, and also objects that do not exactly cross the start or end points (such as a baseball pitch or tennis serve, which start above and in front of the mound or service line).

You can customize the units used for both distances and speeds. In the paid version, you can save recordings to perform the measurements, review, or show off later!

The is the free version of a paid app, "Pocket Speed Gun", and contains banner advertisements. It is intended as a way to test that the paid version will work before purchasing it, though it does not expire. However, because of tax concerns, the paid version is only available in the United States.

Known Issues:

* If you turn your screen off or otherwise navigate away from the app while on the recording screen, it may change to the home screen when you return with an error saying "Fail to connect to camera service." Assuming no other app is using the camera, you can simply return to the recording screen and things should work normally.

* When using the mp4 recording format, stepping through the frames of a video does not work on some devices. On others it is very slow. There is no intended fix for this issue. Please switch back to the tfv format instead.

* Mp4 frames are sometimes blurred or garbled. Sometimes switching to another frame and back helps. The tfv format does not have this issue.
