UX Audit Checklist: Improving Your App’s Conversion

In this guide, we’ll walk through a practical UX audit checklist covering navigation, onboarding, forms, content, CTAs, mobile experience, accessibility, performance, trust and conversion paths. We’ll also look at how to turn audit findings into improvements and when professional web design & development services can help.

The goal is not to redesign everything. Your app may have plenty of visitors, downloads, or sign-ups and still struggle to convert them into active users or paying customers. That can be frustrating because the problem is not always obvious.

Maybe users are dropping off during onboarding. Maybe they cannot find the feature they need. Maybe the checkout process feels too long. Maybe the interface looks good but does not make the next step clear. A UX audit helps you find those problems.

What is a UX audit?

A UX audit is a structured review of a digital product to identify usability problems, friction points and opportunities for improvement.

For an app, that can include reviewing:

• User onboarding
• Navigation
• User flows
• Screen layouts
• Forms
• CTAs
• Content
• Accessibility
• Mobile interactions
• Error messages
• Loading states
• Conversion paths
• Trust signals
• Overall usability

A good audit does not simply say: “This screen doesn’t look good.”

It asks: “What is preventing the user from completing the task?”

Why UX problems affect conversion

Conversion happens when a user takes the action that matters to your business.

Depending on your app, that could be:

Sign up → Start trial → Subscribe → Book → Purchase → Request demo → Complete onboarding

Every unnecessary obstacle creates another opportunity for the user to leave.

The problem may not be the product itself.

It may be the journey.

Before auditing design, understand the conversion goal

You cannot audit UX effectively until you know what success means.

Ask: What is the primary conversion?

For example:

• Create an account
• Complete a purchase
• Book a consultation
• Start a free trial
• Upgrade to paid
• Complete onboarding

What is the secondary conversion?

Maybe:

• Download a guide
• Watch a demo
• Explore a feature
• Contact support

Where does the user enter?

They may come from:

• Google
• Social media
• Paid advertising
• Email
• Referral
• Direct traffic

Where should they end?

This gives you the conversion path you need to audit.

UX audit checklist

1. First impression

The first few seconds matter. When someone opens your app or landing experience, ask:

• Is it immediately clear what the product does?
• Is the main value proposition understandable?
• Is the primary action visible?
• Does the screen feel trustworthy?
• Is there unnecessary information?
• Does the design feel consistent with the brand?
• Is the most important information visually prominent?

Quick test

Show the screen to someone unfamiliar with your product for a few seconds.

Then ask: “What do you think this app does?”

If they cannot answer, you may have a clarity problem.

2. Navigation

Users should not have to learn how your app is organized.

Check:

• Is navigation easy to understand?
• Are labels familiar?
• Are important sections easy to find?
• Is the current location obvious?
• Can users return to previous screens easily?
• Are there too many menu items?
• Are related features grouped logically?
• Is search available when users need it?

A useful navigation structure should feel predictable.

The user should not have to think: “Where would the designer have put this?”

They should simply know where to look.

3. User onboarding

Onboarding is one of the most important conversion points in many apps.

Ask:

• Can users start quickly?
• Are you asking for unnecessary information?
• Can users skip non-essential steps?
• Is the purpose of each step clear?
• Does the app show progress?
• Does the user reach value quickly?
• Are instructions understandable?
• Is there a clear next action?

The key question: How quickly can a new user experience the value of the product?

If users have to complete ten steps before they understand why your product matters, you may have an onboarding problem.

4. Sign-up and login

Every additional field creates friction.

Review:

• Number of fields
• Required vs optional information
• Password requirements
• Social login options
• Error handling
• Password recovery
• Verification process
• Form labels
• Loading behavior

Ask yourself: “Do we really need this information right now?”

If the answer is no, consider asking for it later.

5. Forms

Forms are common conversion blockers.

Check whether:

• Labels are clear
• Fields are logically ordered
• Required fields are obvious
• Errors appear next to the relevant field
• Error messages explain how to fix the problem
• Users don’t lose their information after an error
• The submit button is easy to find
• The form works properly on mobile

Bad error message: “Invalid input.”

Better: “Enter a valid business email address.”

The second one helps the user recover.

6. Calls to action

Your CTA should tell users what happens next.

Weak: Submit

Better: Start my free trial

Weak: Learn more

Better: See how the platform works

Check:

• Is the primary CTA obvious?
• Does the wording describe the action?
• Is there too much competition between CTAs?
• Is the CTA placed where users need it?
• Does the button look clickable?
• Is the next step predictable?

Your primary action should not have to compete with five equally prominent buttons.

7. Content clarity

A user should not need to decode your product.

Review:

• Headlines
• Supporting copy
• Button labels
• Feature descriptions
• Pricing
• Instructions
• Help text
• Error messages

Ask:

Can a first-time user understand this without someone from our company explaining it?

If not, simplify. Good UX often means removing unnecessary complexity rather than adding more information.

8. Visual hierarchy

Look at every important screen.

Ask: What does the user see first?

Then: What do they see second?

Then: What action becomes obvious?

A strong hierarchy can use:

• Size
• Spacing
• Contrast
• Typography
• Position
• Color
• Images

If everything is visually loud, nothing is truly prioritized.

9. Mobile experience

If your app has a mobile interface, don’t treat mobile as a smaller desktop screen.

Check:

• Touch target sizes
• Text readability
• Button placement
• Keyboard behavior
• Scrolling
• Navigation
• Forms
• Image scaling
• Modal behavior
• Orientation
• One-handed usability

A user should not have to pinch, zoom or fight the interface to complete a simple task.

10. Speed and performance

UX is not only visual. Waiting is part of the experience.

Check:

• Initial loading time
• Screen transitions
• API response delays
• Image sizes
• Loading states
• Skeleton screens
• Slow network behavior
• Failed requests
• Offline behavior where relevant

Google’s Core Web Vitals focus on loading performance, responsiveness and visual stability because these factors affect how users experience a page. A beautiful interface that takes too long to respond can still feel broken.

11. Empty states

What happens when there is no data?

For example: “No projects found.” That’s technically an answer. But it is not necessarily useful. A better empty state might say:

No projects yet
Create your first project to start organizing your work.
Create project
Good empty states explain:

What happened → Why → What to do next

12. Error states

Errors are inevitable. The question is whether your app helps users recover.

Check:

• Are errors understandable?
• Does the message explain what went wrong?
• Does it explain what to do?
• Is the error shown close to the problem?
• Is user-entered information preserved?
• Can users retry?

A good error message reduces frustration. A vague error message increases it.

13. Loading states

Never leave users wondering whether the app is working.

Check:

• Is loading visible?
• Does the interface provide feedback?
• Are skeleton screens useful?
• Is the loading time reasonable?
• Can users cancel long operations?
• Does the UI prevent accidental repeated actions?

For example:

Instead of: [Create Account]

immediately after clicking: [Creating your account…]

That small change communicates that the system received the action.

14. Trust and credibility

Conversion requires confidence.

Users may ask themselves: “Can I trust this company?”

Look for:

• Customer reviews
• Testimonials
• Security information
• Contact details
• Clear pricing
• Company information
• Guarantees where appropriate
• Recognizable payment methods
• Privacy information

For apps handling payments or personal information, trust becomes even more important

15. Checkout and payment

If your app includes transactions, audit this flow carefully.

Check:

• Number of steps
• Payment options
• Pricing clarity
• Additional fees
• Coupon handling
• Error recovery
• Confirmation
• Receipt
• Security reassurance
• Mobile usability

Don’t make users work hard to understand what they are paying. Unexpected costs are especially damaging to trust.

16. Search and filtering

For products with lots of content, search can become a critical conversion tool.

Ask:

• Is search easy to find?
• Does it tolerate spelling mistakes?
• Are results relevant?
• Can users filter results?
• Are filters understandable?
• Can users clear filters easily?
• Are there useful zero-result suggestions?

A search box that technically works but produces poor results is still a poor UX.

17. Accessibility

A conversion-focused experience should not exclude users unnecessarily.

Check:

• Color contrast
• Keyboard navigation
• Text size
• Focus states
• Alt text
• Form labels
• Error identification
• Screen-reader compatibility
• Motion preferences
• Touch targets

Accessibility improvements often improve usability for everyone, not only users with disabilities.

18. Consistency

Users learn your interface as they use it. If one button behaves differently from another, or the same action has different labels across screens, confusion increases.

Check consistency in:

• Buttons
• Icons
• Typography
• Colours
• Forms
• Navigation
• Spacing
• Terminology
• Interactions
• Notifications

A design system can help maintain this consistency as your product grows.

19. The complete conversion journey

Now stop looking at individual screens. Walk through the entire experience.

For example:

Ad / Search

     ↓

Landing page

     ↓

Sign up

     ↓

Onboarding

     ↓

First action

     ↓

Product value

     ↓

Upgrade

     ↓

Payment

     ↓

Confirmation

Ask at every stage: What could make the user stop here?

This question can reveal problems that are invisible when screens are reviewed individually.

20. Use analytics to find the biggest problems

Your UX audit should not rely only on someone’s opinion.

Look at actual behaviour.

Useful data includes:

• Conversion rate
• Drop-off rate
• Funnel data
• Session recordings
• Heatmaps
• Search queries
• Form abandonment
• Feature usage
• Support tickets
• Customer feedback

Turn your audit into a priority list

One of the biggest mistakes is creating a huge UX report and then doing nothing with it.

Don’t just list 50 problems.

Prioritise them. A simple framework is:

Issue	User impact	Business impact	Effort	Priority
Confusing onboarding	High	High	Medium	Critical
Small icon issue	Low	Low	Low	Low
Checkout friction	High	High	High	Critical
Weak empty state	Medium	Medium	Low	Medium
Navigation labels	High	Medium	Low	High

A simple UX audit scoring system

You can also score important areas from 1 to 5.

1 = Major problem

Users are likely to struggle.

2 = Needs significant improvement

The experience works, but friction is obvious.

3 = Acceptable

No major problem, but improvement is possible.

4 = Strong

Works well for most users.

5 = Excellent

Clear, efficient and highly usable.

Score:

Navigation: 3/5

Onboarding: 2/5

Forms: 4/5

Checkout: 2/5

Mobile UX: 3/5

Now you have a starting point.

What should you fix first?

Start with problems that are:

High impact + High frequency + Reasonable effort

For example:
Fix first A confusing checkout button that affects thousands of users.

Fix later A minor spacing inconsistency on an internal screen.

The goal is not to make every screen perfect. The goal is to improve the experience where it matters most.

When web design and development need to work together

Sometimes a UX problem cannot be solved through design alone.

For example:

Problem: The checkout takes eight seconds to load.

Changing the button color will not solve that.

You may need:

• Front-end optimization
• API improvements
• Database optimization
• Image optimization
• Caching
• Code changes
• Infrastructure improvements

This is why strong web design & development services should not treat design and development as two completely disconnected activities. The experience users see is the result of both.

UX audit vs. redesign

These are different.

UX audit Finds problems.
UX redesign Creates solutions.
Development Turns those solutions into a working product.

How Code and Core can help

At Code and Core, we approach UX as part of the wider digital product experience rather than treating design as something that happens separately from development.

A UX improvement needs to work visually, functionally and technically.

That means looking at:

User behavior → Experience → Design → Development → Performance

Our teams work across UX/UI design, web development and custom software development, which allows UX findings to be translated into practical design and development improvements.

Whether the goal is improving an existing application, redesigning a website, simplifying a user journey or building a digital product from scratch, the process should start by understanding the problem rather than immediately changing the interface.

Final takeaway

Your conversion rate isn’t always a marketing problem. Sometimes users are interested and ready to act, but the experience makes them stop. It could be a confusing screen, long form, slow page, unclear message, or difficult navigation. A UX audit helps you find the friction.

Find it → understand it → fix it → measure it.

That’s how UX becomes more than design, it becomes a practical way to improve conversions. If you’re not sure where users are dropping off, Code and Core can audit your experience, identify key friction points, and turn insights into practical improvements.

Find the friction before it costs you more conversions.
