That Convert

Over 75% of mobile apps are abandoned within 24 hours of download because of clunky onboarding, poor thumb-zone ergonomics, and uninspired interfaces. I combine behavioral conversion psychology with native Apple HIG and Material Design 3 standards to architect mobile apps users open daily—and happily pay to subscribe to.

THE MOBILE RETENTION BOTTLENECK

Why 80% of Downloaded Mobile Apps Get Deleted After the First Open

01 / VALUE FIRST

High-Friction Onboarding & Weak Subscription Paywalls

Paying for App Store installs is wasted money if users hit a cold registration wall before experiencing value. Progressive personalization quizzes, clear trial-reminder timelines, and psychologically anchored paywalls keep Day-1 retention and paid trials moving.

02 / THUMB ZONE

Desktop UX Crammed Onto a 6-Inch Smartphone Screen

Mobile users navigate with one thumb while on the move. Tiny tap targets, awkward top-corner menus, and non-native gestures turn simple flows into work. Bottom sheets and thumb-zone architecture make the product feel effortless.

03 / HANDOFF

Missing Mobile Edge Cases That Delay App Store Approval

A real app needs safe-area notches, keyboard overlays, biometric states, offline banners, and dark-mode OLED contrast. Missing these in Figma doubles React Native or Flutter development costs and slows launch.
