I share my great experience with kinemaster editor app. When I install it in my android phone just because I want to edit videos so that I easly increase my popularity in YouTube because I want a best youtuber. When I used it I found that there is very interesting features which generally I seen in paid software but in kinemaster I see this for free such as background eraser, text design, animation creations etc.
Also it increase video quality and afterwards editing by kinemaster its like mirror shine.
So my experience with my personal opinion that must used it because I found very best features which you also used it once for making video quality better.
