A new app called One Second Everyday is perfect for parents who feel their kids are growing up so fast and want to document it all. The idea is just as the name implies: one second of video, every day. One second to represent your children’s days and adventures. One second to capture everything from a special moment to everyday routine. And at the end of the year — or the week, or the month, or whatever length of time you choose — it compiles all of those fleeting clips into one wonderfully erratic video. Try it. It is easy and it’s free.
