Leap Second is the only one-second video app you’ll ever need! Capture your favourite memories and showcase the finest moments of your life in style. We make it super easy to trim your videos and stitch them together to form a mini montage of your life. Remember, every second counts!

Videos are automatically sorted by date and populated inside the integrated calendar, making it super easy to organise your videos. You know how easy it is to accumulate 10,000 pictures and videos, and how hard it is to find the one you want to use. Don’t stress, we’ve got your back.

Not physically flexible - you know, as in bendy – but we do support both landscape and portrait videos. If you fancy yourself as a video editor, you can edit your videos as much as you like in your device’s photo or video editing app, then just add them into the Leap Second calendar when you’re happy!

Enable this nifty setting and if you want all of your one second videos to be backed up to your iCloud library. Never lose a second, never lose a memory! You can use Leap Second across any device synced to your iCloud account. Awesome, right?

You’ve just made the most epic one second video montage of all time. Maybe it’s Hollywood grade stuff and you want to see what your friends think. We’ve integrated all of your favourite social media apps with Leap Second so you can share your creations with a few taps! Or maybe you want to keep your video collages private, that’s cool too.

Make memories. Tell stories. Download Leap Second for free today!

I tried a one week free trial and I wanted to cancel and it didnt let me.

I had 10 months of videos and wanted so badly to complete a year. Went into the app one day and everything was gone. And the “leap second” album on my phone is empty too. So very dissapointed and let down.

Hi there! If you reach out to me at I can look into this for you.
Check if you can see the videos in the album "hidden" or if they appear in the album "recently deleted". If you can see them there you can add them back to the album and they should appear.
