Android Apps

A list of Android apps (feel free to add iOS apps below) which take timelapse image sequences, so you can use them on a balloon mapping rig for aerial photography. Most important is whether they capture in the full resolution of the camera, and/or if they compress to make it into a video.

• Timelapse - $1.99, captures up to 2048x1536

More recently released, look pretty good but untested:

• Timelapse Free - This one has "Timelapse,compass,GPS tagging,full EXIF details", and seems to save as a file.
• LapseIt Pro
