How to Redesign a Bad App: A UX Designer's Step-by-Step Approach
A redesign is not simply “make the screens prettier.” Start by finding the real friction, understanding users and constraints, then redesign the experience around evidence and clear priorities.
The 7-step app redesign roadmap
Follow the sequence from diagnosis to validation. Click each stage to see what to do.
Audit
Find usability, accessibility, content, navigation and consistency issues.
Understand users
Identify users, goals, context, behaviours and pain points.
Prioritise
Separate high-impact problems from cosmetic improvements.
Restructure
Improve information architecture, navigation and task flows.
Wireframe
Explore solutions before committing to polished visual design.
Design & prototype
Create a coherent UI and realistic interaction states.
Validate
Test key tasks, learn from feedback and iterate.
What are you actually redesigning?
Different problems need different UX responses.
Usability problems
Look for confusing flows, unclear actions, unnecessary steps, poor feedback and errors that stop users completing important tasks.
Content problems
Review labels, instructions, empty states, error messages and information hierarchy. Good UX can fail when the content does not help users act.
Visual UI problems
Audit hierarchy, spacing, typography, components, contrast and consistency—but only after understanding the underlying experience.
Accessibility problems
Consider keyboard access, readable content, colour contrast, focus states, target sizes and assistive-technology needs appropriate to the product.
Interactive bad-app audit
Tick the problems you discover. Use the score as a prompt for deeper investigation, not as proof that an app is objectively “bad.”

From problem to redesigned experience
Do not skip the middle. Your portfolio becomes stronger when it shows how the redesign evolved.
Capture the current experience
Document the existing flow and key screens before changing them.
Frame the problem
Turn observations into specific user-centred problem statements.
Explore alternatives
Sketch multiple ways to solve the highest-priority problems.
Build the new flow
Improve structure and interactions before visual polish.
Prototype key tasks
Make the important interactions realistic enough to review.
Test and iterate
Use feedback to refine the redesign and explain what changed.
