Frequently Asked Questions

Do you design for both iOS and Android?

Yes. We design mobile applications tailored for cross-platform frameworks like React Native and Flutter, while respecting platform-specific navigation patterns (such as iOS swipe-to-back and Android system back buttons).

How do you ensure the app feels intuitive to users?

We design within the natural "thumb zone" for one-handed operation, maintain consistent 44x44pt minimum touch targets, use recognizable iconography, and validate clickable prototypes before coding begins.

Can you design App Store screenshots and icons?

Yes, we design complete store presentation packages including high-resolution app icons, screenshot mockups highlighting core features, and marketing graphics.

Do you provide animations and micro-interaction specs?

Yes, we provide interactive prototypes demonstrating ease curves, transition timings, and micro-interactions for button presses and navigation transitions.

What is the turnaround time for a complete mobile app design?

A comprehensive mobile app design (30 to 50 screens including onboarding, profile, core feeds, and settings) usually takes 4 to 6 weeks.
