The youtube creator app is useful for those creators who want to keep a watch on analytics on the go on their mobile. the concept of the app is to provide necessary video analytics and facilitating minor edits about video.the layout and the design of the app is excellent and user friendly . it is not complex to use. all information is provided with one click. the main features of the app includes adding tags, description, knowing your views, subscribers, watch time, estimated revenue, etc.you can also change the thumbnail of the video. personally speaking the youtube creator studio is extremely useful for me. I would give it 8/10 and would recommend some changes like adding add break in video and real time subscriber count.
