InShot has been my go-to video editor for four years and it has never disappointed. You can use it for free, and even without paying for extra features, you can already create clean, decent, and engaging video edits. It is not boring to use, and the tools are intuitive enough to let you learn real editing skills directly on your iPhone. The paid features are there if you want more, but the free version alone is powerful enough to produce quality results.
