How to Build a Mobile App
Define the app’s main job and intended users, then choose native development or a cross-platform approach based on your needs and skills. Build a small prototype, test it on real devices, and review the relevant app-store requirements before release.
Have this ready
- A clear user problem

I can walk you through it in a Magic Box, show you the exact clicks, or do it with you and keep the recording. You log in yourself; I never see your password.
