Star Footprint

Do you believe that the Earth is round and it’s spinning around its axe?

Or do you believe that the Universe is spinning around the Earth?

If so, do you know the direction?

This small app allows you to answer all these questions.

Wait for the evening. Put your device into a place where it can see stars. And order it to watch the changes. Next morning check the results.

This app's main purpose is to take pictures of stars in different moments of the night and draw star traces on the sky. As a result you’ll get lines of stars’ chalk on the blackboard of the unlimited Universe.

Before using it, try to take a picture of stars with your standard camera app. Maybe stars are too small for your device.

If it's OK do next:

1. Choose interval between photos and the time of the last photo.

2. Set your device into a place where it can see stars. You may use preview.

3. Click Start and don't move the device until morning.

Note: you may plug your device into a power supply or decrease the time of inactivity before the device fall asleep. If you can't find photos look at SD-card/DCIM/StarFootprint.

*Advanced camera parameters include antibanding, white balance, RGB565, PNG format, exposure correction. (It affects only the result photo)

**If your device under Android 6.0 Marshmallow don’t use interval less than 15 min or plug the device into a power supply.
