# Build your first mobile app

URL: https://gocutline.com/playbooks/start-a-mobile-app-as-a-beginner/

Build your first mobile app: Pick one tiny job the app does for one person. Most first apps fail by trying to do ten. 1) Write the one job your app does in one sentence. 2) Sketch the three screens it needs on paper. 3) Show the sketch to five people who have that problem.

## The steps
1. Write the one job your app does in one sentence.
2. Sketch the three screens it needs on paper.
3. Show the sketch to five people who have that problem.
4. Build it with whatever you can ship fastest, including no-code tools or AI help.
5. Put it in the hands of 10 people through a test release before you launch it.
6. Launch, ask people why they stopped using it, and fix that first.
