With so many apps that do the same thing, the key to mobile success often comes down to how easy an app is to use. To create an app that users come back to again and again, simplify content and focus on an intuitive experience.
To keep users attention, avoid overloading them with content and keep messaging clear and concise, with the most relevant information at the right moment.
Because mobile devices are used “on the go,” make sure actions are reduced to one per screen and allow users to save and re-engage with the app later.
Guide the user along their journey by combining recognized functions from other apps with your understanding of what the user is trying to accomplish.
Design an onboarding experience that gives users the information they need, but don’t let the experience feel generic or interruptive.
Every device has different conventions—make sure not to carry behaviours over from other platforms or you’ll compromise user experience and conversion.
Make controls between 7 and 10mm in size so that they’re easy for users to tap without missing their target or feeling frustrated.
Think about the hand’s position when placing controls, and make sure top-level destinations are within the thumb’s reach.
Design your app for the entire user journey rather than a single interaction, so that users can switch between devices without interrupting their flow.
Delight your users with carefully considered details—like animated microinteractions, animated feedbacks, or in-app sounds that show your app’s personality.
Resist the temptation to squeeze everything from desktop down so that it all fits—instead stick to the most important text at no smaller than 11 points.
No one really wants to be interrupted, much less for something useless while they’re in the middle of something important. Avoid interrupting users by asking them to rate your app if they’ve only recently downloaded it.
Test your app with users on a variety of mobile devices to see how the design really performs, and continue to make adjustments throughout the life of the app.
