There are luma and movie elves on ipad. Luma is expensive and charged annually, but the editing function is really strong; The editing function of the movie wizard is also very powerful. I am satisfied with other editing functions except video keying, such as matting, text animation, mask, moving mosaic, especially the moving point, which allows your material to move at will. Of course, the most satisfactory thing is that it is cheap, and tens of dollars can last a lifetime. There is no need to charge monthly or yearly, which is one of my favorite and most admired reasons.
