In my early pick for 2017’s “App Description of the Year,” Moment’s Eun Seong Kim tells a story about his frustration and disappointment after the dreaded “Storage Almost Full” message caused him to miss an exciting moment at a Toronto Raptors basketball game. It’s an elevator pitch that ends with the question that drew me to Moment: “What if I could keep video recording but only capture the last 5 seconds?”

I instantly identified with Kim’s hypothetical. When I’m shooting video, I’m often only looking for the 5 or 10 seconds of action, but I’m stuck with a multi-minute clip that I have to edit. Moreover, even though my iPhone has plenty of storage now, there’s a real chance I will run into the same problem in the future.

After I tried Moment, I was sold – the app lets you record video for as long as you want and, when you’ve gotten the shot you need, exports the last 5 or 10 seconds to Photos. Because Moment is constantly discarding the portion of what you are recording that is older than the last 5 or 10 seconds, the video you’re shooting doesn’t take up a significant portion of your storage space, so you’re free to have the video running as long as you’d like before getting the right shot.

In practice, it’s as simple as it sounds. I set my phone up, pressed record, and after a couple of minutes ended the recording. When I opened Photos, the video was there immediately as a clip of the last 5 seconds I recorded.

Although it’s a simple utility, Moment solves the problem of having to delete photos and videos to clear room for more. Lazy editors will appreciate it, too. If you fall into either of those categories, give Moment a try.

You can pick up Moment in the App Store for $2.99.
