Performance and Flickering of my Ionic app


Hi ,I have designed an app in ionic framework with angular script. Everything works fine, but the performance of app is very slow. UI rendering is taking time to load the widgets. Flickering of screens occur while traversing from one screen to another. I have come across many tutorials but i cant come to a proper solution. Please anyone help me out with this issue so that I can make my app smooth and faster. Thanks in advance.
