Mouthshut is a wonderful platform to express views about any products, services, place and so on. One can download Mouthshut application in their mobile from Play Store. This application is user friendly and works great. Updates are done time to time.
It has options to write reviews, share reviews, comments on reviews, rate on reviews, and invite friends.
One can see their points, notifications, review posted, comments, invite code, contest, help etc by clicking on top most left side three horizontal lines.
I recommend this application but for editing the review and all we have to use website.
