The subscription-based CT Pro software is one of the most intricate editing apps for smartphones we've seen. The app allows you to shoot then edit footage with a slew of features that continually get updated. You can either shoot at 25 or 30 fps HD using either HEVC or H.264 Codecs in real-time and at a real constant frame rate. It's audio mixing options are very intuitive, and if you're into live broadcasting, the app has options for that as well.
It's free to try and available to download here. The monthly fee is $25 and there's a yearly purchase option, too.
