A more usable app is more user engaging and has less chances of app uninstallation. It is a presentation of basic user experience principles to your advantage. Better UX increases user retention.
Here are a few tips that will help you to design better user experience:
Usability and User goals: You are standing on a street and it’s raining heavily. You open a cab booking app. Being a user, what is the one thing you are hoping to get done as soon as the app opens?
‘Get a cab at the earliest’.
If your users have a possibility of being into such situations, design your app accordingly. Create a UX flow which allows booking a cab in minimum steps and time.
Define a clear CTA: CTA (Call-to-action) button, this is the button that makes sure that the user gets the cab and if we name it as ‘submit’ rather than ‘request for a cab’. Will it be understandable by the user or it will be confusing? The CTA’s should be more relatable to the user. And, it should be clearly visible and easily approachable as it is hard to reach to the top-left corner of the screen for a right-handed user unless you use your both hands
Design for fat thumbs as well: The action buttons should be bigger and should be placed at a fair distance for easier app navigation. If the action buttons are smaller, then it could be frustrating for the user and could result in app uninstallation.
Don’t drain the battery: If the app is heavy on calculations and the last thing the user needs when stuck in a city with heavy rainfall that their mobile battery is not running out.
Keep the UI simple- lesser color and shorter navigations and to limit the background services. I hope the tips will be helpful to you for improving user experience and increasing user retention.
