A website squeezed into an app
Desktop thinking on a small screen creates tiny targets, long forms and buried actions.

Flows, screens and prototypes designed for thumbs, small screens and short attention spans.
Designing for a phone is different: one hand, small screens, interruptions and platform habits people expect. We design app experiences around those realities, test them on real devices and hand over designs developers can build exactly.

Sound familiar?
The problems we hear most often before someone asks us about app UI/UX design.
02
Onboarding that loses people
Long sign-up flows and permission requests up front make new users quit before they see any value.
03
Ignoring platform habits
Controls that behave differently from what iPhone or Android users expect make the app feel wrong.
What's included
01
Flows for key tasks
The few tasks users do most, designed to be quick and obvious.
02
Onboarding
First-run experience that shows value fast and asks for permissions at the right moment.
03
Platform-aware UI
Designs that respect iOS and Android conventions while staying on brand.
04
Light and dark modes
Both themes designed and checked for contrast.
05
On-device prototypes
Interactive prototypes tested on real phones, not just on a monitor.
06
Developer handover
Components, tokens, specs and assets ready for your developers.
