Onboarding Flow
More than 80% of apps are deleted after their first use. That's why it's so important to test how you onboard users and show the value of your app.
Requesting Permissions
With more access, you can offer a better experience. Try testing the right way to ask your users for permissions.
Feature Discovery
Should users search? Should they use your menu? You have the opportunity to optimize your users' flow through your app.
Inputs and Interactions
Every chance for a user to interact with your app is a chance for you to optimize. Test different types of forms and inputs.
Re-engagement
Acquisition is tough. Re-acquisition is tougher. You can optimize the ways you re-engage your users to keep them active.
Phased Rollouts
Mobile split testing and multivariate testing give you an easy way to test new features and quickly remove the ones that don't work.
