Splice is a powerful video editing app that works brilliantly on your phone. The free app lets you pick video clips, add transitions, edit them together, speed them up or slow them down, and add text overlays, too. You can also add music from the Splice library or your own and edit your video in time to your music. This app is really handy for you to trim your videos to the perfect 15-second Instagram Story length, too.
Available on iOS.
