Estimated time: 1–2 hoursUpdated: 28 September 2026

Use this guide when you have an idea for an app or website and are tempted to start coding straight away. Have paper or a notes document, and ideally someone who might use the app to talk to.

Step by step

  1. Describe the problem and users

    Write one or two sentences on the problem the app solves and who has it. List the types of users, such as customer and admin. For each, note what they want to achieve.
