Hey guys, I would want to share this app which is created by one of XDA member, krishneelg3 who actually worked on this alternate Instagram application which gives the refreshing Flat UI looks that is similar to the IOS 7 official Instagram application. To be honest, this is just an UI makeover application which replaces the stock official Instagram app, nothing more and nothing less. Some screenshots is included which gives you a rough idea on how the app looks like compared to the original one.

Do take note that you have to uninstall the official Instagram app that you downloaded from the Google Play in order to get this unofficial Instagram app side-loaded to your device. How to install? It is a simple APK file which you can download directly to your mobile device and get it installed automatically. If you receive an error which stops you from installing this APK file, head over to Settings>Security>Unknown Sources. Tick the Unknown Sources option. And you’re good to go. Go ahead and try this application, who knows you might end up remaining with this application instead of the official one, until the official one gets the IOS 7 UI facelift.
