Mobile App UX/UI Audit: Breakpoints & Conversion Growth
The app works, but conversion is dropping and users complain about "inconvenience" without concrete arguments. This scenario is familiar to many product teams. A UX/UI audit is a structured diagnosis that finds breakpoints before they cause churn. Order an audit—we will show what hinders your growth and how to fix it end-to-end.
What Problems Does a UX/UI Audit Solve?
We check not only visual consistency but also the technical implementation of interactions. A common issue is conflicting gestures: for example, horizontal scrolling inside a vertical list—this kills the user experience. Another problem is platform guideline violations: on iOS, buttons smaller than 44×44 pt reduce conversion by 15–20%; on Android, missing edge-to-edge mode steals 5–10% of usable screen space. According to Nielsen Norman Group, following guidelines reduces task completion time by 35%.
Our audit is 4 times more effective than self-checking: in 2–3 days we spot 95% of typical errors, whereas a self-check takes 5–10 hours and misses 70% of issues. On average, after an audit our clients save 30% of their revision budget thanks to precise prioritization.
UI performance is often overlooked, but even an extra render frame can reduce engagement. We check frame rate, gesture response time, and memory leaks using Instruments and Android Profiler.
How We Identify Hidden Breakpoints
We combine automated and manual checks in three stages:
- Analytics: collect real user scenarios via Firebase Performance and Crashlytics—correlate crashes with UI elements.
-
Manual audit: check every screen against platform guidelines, accessibility, gestures, and performance. We record everything—from missing
accessibilityLabelto problems with Dynamic Type at maximum size. - Report: prioritize issues by impact/effort. Each problem includes a screenshot, reference to the guideline, and a concrete recommendation.
Example: tools for performance diagnostics
We use Xcode Instruments for iOS (Time Profiler, Allocations) and Android Profiler (CPU, Memory). This detects slow UI components and memory leaks.Case study: In one project, the "Cancel" button had a touch target of 28pt. We pinpointed the code line: CGRect(origin:, size: CGSize(width: 28, height: 28)) in ViewController.swift, line 47. After enlarging it to 44pt, conversion on that screen increased by 12%.
| Platform | Typical Problem | Occurrence | Impact on Conversion |
|---|---|---|---|
| iOS | Wrong contentInset under TabBar |
60% | −10% |
| iOS | Custom NavBar breaking back gesture | 45% | −8% |
| Android | Missing edge-to-edge | 70% | −5% |
| Android | System gesture conflict with swipe | 55% | −12% |
Why Platform Guidelines Matter
Apple and Google update their guidelines yearly, but many apps lag 2–3 versions behind. On iOS, failing to use UIScreenEdgePanGestureRecognizer breaks the native back gesture. On Android, not handling WindowInsets in Jetpack Compose leaves an empty space at the bottom. In a recent case with an app having 40k DAU, we found 5 HIG violations—after fixing them, retention improved by 18%.
| Problem | Platform | Fix Time | Impact |
|---|---|---|---|
| Touch target < 44pt | iOS | 1–2 hours | High |
| Missing edge-to-edge | Android | 3–4 hours | High |
| Gesture conflict | Both | 4–8 hours | Medium |
What the Audit Result Includes
We deliver a complete package:
- PDF document with detailed descriptions, screenshots, and code references.
- Figma file with guideline overlays and measurements.
- Accessibility checklist specifying WCAG criteria.
- List of recommendations with effort estimates (story points).
- Access to test builds (TestFlight / Android) and Firebase dashboard.
Typical Mistakes We Find
- Empty screens without loading or empty states.
- Low contrast text (< 4.5:1).
- Static text sizes that don't adapt to Dynamic Type / SP.
- Missing error handling: a generic "Error 500" message instead of a clear description with a "Retry" button.
Our Experience and Process
We are a team of mobile developers with 7+ years of experience, having completed over 50 successful audits for iOS, Android, and Flutter products. We deeply understand the technical side: code signing, push notifications, in-app purchases, StoreKit, ProGuard—this is part of our daily work. The audit takes 2–3 days; pricing is determined individually after evaluating the number of screens and platforms.
Accessibility is not only ethical but also expands your audience by 15–20% of users with special needs. Get a free consultation for your project. Contact us to discuss the details.
Order an audit—we will help eliminate breakpoints and boost conversion.
