I don't think I captured every single day but I know I got most of them and it feels great to keep this going for another year. A lot happened in 2015 but the most obvious (or maybe just to me) is that I switched back from Android to iPhone and the audio/video quality of the videos makes a jump for the better in the second half of 2015.
As I've mentioned before, I highly recommend everyone keep a video journal like this; you'll thank yourself later. Oh and in the beginning, you'll forget days left and right but don't get discouraged. Keep with it.
