gps4camera vs Questovery

This little app is, at the heart, is just a GPS track recorder. While it's recording tracks, it has all the data necessary to show movement information. So a bike computer-like screen was added (although it should work for cars and other vehicles). In addition, there is a screen which shows the current date and time along with a QR code. Both are updated once a second. Use your camera to take a picture of the screen and this can be used to sync the phone time with the photos from the camera. Note, this app does NOT sync the phone's time directly with the camera. The idea is to take a photo with the QR code, parse the QR code and sync the QR code photo's time with the timestamp embedded in the QR code. A secondary script, qrfinder, is available (view the app settings -> how to for more info).
