There’s a reason why Apple’s free apps pepper this list; they have a knack of creating brilliantly functional and easy-to-use apps that are loaded with original features. Their ubiquitous iMovie app does everything a video editor should do. All you have to do is drop in your clips, trim them to size and add in built-in music, effects and animated titles. Nice extras include split-screen effects, 10 high-fidelity filters, green-screen effects and the ability to make Hollywood-style trailers. As it’s Apple, you can switch between your devices with impunity, using AirDrop and iCloud Drive, to create your final cut.
