The kinemaster app is the best video editing app so far available in the smartphone market. it is very powerful and has tons of features. the main concept of the app is video editing. it is easy to use and simple. the layout of the app is simple and is user friendly. the logo of the app is also great. the design of the app is that you get all the setting things on left side and tools on right side. the app has different features according to the phone in which you use. the basic features that are available are trimming, image overlay, text overlay, FX, music overlay, themes for video, animation for images and text and audio boost. if you have a phone which has snapdragon 820 or above you are elegible for chroma key feature and video overlay feature. the chroma key feature is just like green screen feature. the app is real useful for creating video for youtube if you do not own a pc for editing video. it aso has that chroma key feature which generally exists only in pc . but one thing that is bad about this app is that it has in app purchases. so if you want to remove watermark you need to pay some monthly charge. even for getting some FX, theme and music you need to pay. overall this app is great. I personally use this app on my oneplus 5 for making youtube videos. I would rate it 8/10 . the remaining points are deducted because of in app purchases.
