Magisto is a very simple video editor app. With this app, you don’t get any features such as adding text overlays, tilt shifts, etc to your video. However, the charm of this app lies in its simplicity. Within the app, you can import your photos and videos, and choose a theme for the video. There are a number of themes available, such as dance, among many others. Once you’ve done that, you get the option to add music to the video, as well as options to decide how long you want the video to be.
Funimate is one of the surprisingly popular, but not overly powerful video editor apps. It bills itself as being a great app for making music videos or simple videos out of the stuff you already have on your device. There are 15 video filters that you can play with and the creation process is fairly painless. This isn’t something you’d want to use on a serious video. It has things like video effects. However, it's better for short little social media posts rather than actual video production. You can download it for free to try it out yourself.
Imo is a simple video calling and chatting app. It boasts compatibility for 2G, 3G, 4G, and LTE networks. That makes it good for those stuck on worse connections. It's also compatible with both iOS and Android. Otherwise, there isn't much to this one. That's not necessarily a bad thing. Aside from text chatting and video calling, this app doesn't have any bloat holding you back from a simple experience. It's free to download and use. The only thing you'll need to deal with is some advertising.
Talking about features, LumaFusion supports up to 6 video and audio tracks for for photos, videos, audio, titles and graphics with an additional 6 audio tracks narration, music and sound effects. You also get a magnetic timeline which makes it really easy to manipulate clips once they are imported. There’s dozens of transitions and effects with the ability to layer effects. Finally, it also comes with dozens of royalty free music, sound effects, and more. If you really need a professional grade video editing app for your iPhone, you should definitely buy LumaFusion.
KineMaster is one of the most powerful video editor apps available. You can do the basics like most of these other video editors can. However, this one includes multiple video, image and effect layers. Additionally, there are audio filters, chroma key (for your green screen fans out there), various video effects, transitions, and more. It's not as powerful as a full desktop editor. However, this gets much closer than most other competitors. We would recommend this for actual video production (at least for stuff like YouTube). You can use it for free in trial mode for a while. However, you'll need the $4.99 per month subscription to get everything forever.
