A manageable app project begins with one user task and a clear data model. Plan error states and accessibility alongside the successful screen flow.
Before you begin
Use a supported development setup and a small sample app. Record the toolchain, target and test device or simulator.
Work through the idea
Define a user task and the states the interface must represent. Test normal, empty and failed states as applicable, and consider larger text, narrow layouts and interrupted operations. Keep sample data fictional. Distinguish simulator checks from features that require validation on the intended physical device.
- Write a short user story
- Sketch the main navigation
- Define data and failure states
Practice task
Plan a fictional personal task app with add, complete and delete behavior.
Check your result
Submit the flow, model, acceptance criteria and a small first milestone.
A mistake to avoid
Do not add authentication, notifications and cloud sync before the core task works.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
