[Android][App] Need help finding out the reason for high uninstall rate

I have an app on google play called ‘Superjokes - Free Funny Jokes’ . I have a low constant rate of download for the app but the problem is that more than 90% of my users keep uninstalling the app. I dont understand the reason why. I have a good looking design. Features are fine too. There can be improvement but nothing major like crashes and all that can make users uninstall the app. Can you have a look at my app and tell me what you find odd. Please help a fellow developer out… I am happy to help anyone else in need.
