I am using mouthshut app and found that it is best app for rating and review. the app interface is very good and no any difficulty found while I am using the mobile app. The app work as like website work, clearly smooth and gently. when you open the app a pop up window appear and gave information about latest thing which you need to review. on the homepage you found all categories like Automotive, Books, Real Estate, Computer, Education, Electronics, Employee, Health, Home, Mobile, Movies etc. You can search also on the write corner of the app on the search bar. it has four major tab like Categories, Feeds, More, Message and You. in the feed menu you can see Review of the Day and people you follow. On more section you can find sub tab like Write a Review, Upload Photo, Add a product and compare the product. Now on Message tab you can see recent messages by Mouthshut Team. After this you have "You" tab option where your can find personal details like profile, notification, draft, recent visits, earned ms point, invite friends etc. you can edit your personal details here and reset your password or sign out option is also available. so I think the app interface is good and very familiar with users. Thank You
