What this service entails

Apps people keep on their home screen

Mobile users decide in seconds. I map your core loop first — the one action that must feel effortless — then design onboarding, empty states, notifications and paywalls around it, testing each on real devices with real thumbs.

    App flows & IA — navigation that survives feature growth.

  • ✓

    High-fidelity prototypes — tap-through builds for testing and stakeholders.

  • ✓

    iOS & Android kits — platform-correct components, dark mode included.

  • ✓

    Store assets — screenshots and preview guidance for launch.
