Frequently Asked Questions

Everything you need to know about app UI analysis

What does the app UI analysis check?
BlurTest evaluates 8 key metrics: touch target sizes (minimum 44pt/48dp), visual hierarchy flow, navigation clarity, thumb zone placement, information density, text readability, platform consistency (iOS HIG / Material Design), and feedback states (loading, empty, error). Each metric is scored 0-10 with detailed explanations and actionable recommendations.
Does it work for both iOS and Android apps?
Yes. The AI automatically detects whether your screenshot is from iOS or Android based on visual cues (navigation bars, system UI, typography). It then evaluates against the appropriate guidelines — Apple Human Interface Guidelines for iOS and Material Design 3 for Android.
What is the thumb zone and why does it matter?
The thumb zone refers to the areas of a phone screen that are easily reachable with one hand. Research by Steven Hoober shows 49% of users hold their phone with one hand and 75% of interactions are thumb-driven. The bottom-center of the screen is the 'green zone' (easy reach), while top corners are the 'red zone' (hard to reach). Primary actions like CTAs should be in the green zone.
What kind of app screens can I analyze?
Any app screen works — onboarding flows, home screens, product detail pages, settings, forms, modals, bottom sheets, and more. The AI classifies the screen type and adjusts its evaluation accordingly. For best results, use full-screen screenshots without device bezels.
How is this different from usability testing?
Traditional usability testing requires real users, takes weeks, and costs thousands. BlurTest gives you an instant expert-level audit based on established platform guidelines and mobile UX research. Use BlurTest during design iterations to catch issues early, then validate with real users for final confirmation.
What are the minimum touch target sizes?
Apple recommends 44x44 points minimum for iOS, Google recommends 48x48 dp for Android, and WCAG 2.2 Level AA requires 24x24 CSS pixels. Research shows targets under 44x44px have 3x higher error rates. BlurTest checks every interactive element against these standards.
What does the Full Playbook include for app UI analysis?
The Full Playbook (3 credits) is our most comprehensive app analysis. You get 30 prioritized recommendations, layout suggestions for each interface area, component swap recommendations, micro-interaction pattern suggestions, CSS snippets, and an A/B test roadmap — all aligned with Apple HIG and Material Design 3 guidelines.
Can I get layout suggestions and component recommendations for my app?
Yes — the Full Playbook tier includes specific layout improvements for each interface area, component swap recommendations with platform-appropriate alternatives, and micro-interaction patterns. Each recommendation references the relevant platform guideline (iOS HIG or Material Design) for your team to implement.
