Services / Mobile app design
Apps people keep on their home screen.
iOS and Android apps designed around the few moments that matter: the first launch, the thing people come back for, and the reason they return tomorrow.
Why it matters
The phone is the main screen.

Pew Research Center, 2026of US adults are smartphone-only: no home broadband, so the phone is how they get online.

World Health Organization, 2023A day in the app
Five moments decide whether an app stays.
We design each one on purpose, then test it on real phones with real people.
- 01 · First launchMake sense in five seconds.
One clear promise, one primary action, and permission requests only when the person can see why.
- 02 · OnboardingGet to the good part fast.
Ask only what the first useful screen needs. Everything else can wait until later.
- 03 · The core loopThe thing they came back for.
The two or three actions people repeat, placed where thumbs reach and never more than a tap away.
- 04 · A notificationWorth the buzz.
Timely, specific and easy to switch off. Every notification opens exactly where it promised.
- 05 · Coming backPick up where they left off.
Saved state, a friendly empty state, and a clear sign of what changed since last time.
One product, two platforms
Native on iPhone. Native on Android.
Same brand, same structure, and each platform's own habits, so nobody has to learn your app twice.

Material Design 3The store page
Your first screen is in the store.
Before anyone opens your app, they judge its icon and screenshots. We design those as carefully as the app itself.
- App iconReadable at every size, from the home screen to the store search results.
- ScreenshotsA set that tells the story in order, written for people who only glance.
- Preview videoA short look at the core loop, cut for the store's sizes.
- Listing copyTitle, subtitle and description outline that say what it does, plainly.
What you get.
- User flows for every key journey

- A component library in Figma
- App icon and store screenshots
- Usability testing rounds

Goals, users, and the one journey that matters most.

Flows and first screens, tested as a clickable prototype.
- 03Your review
You and your users react; we gather it all in one place.

Handoff to your developers, store assets, and support while they build.
Fixed-price projects from $1K, or a design team on a monthly retainer from $3K. One-off projects are 50% to start, 50% on launch.
Good questions.
Designing a web app or SaaS dashboard? See Interface and app design. Adding an AI assistant to your app? See Chat experience design.
Do you design for iOS and Android?
Yes. We design one product that feels native on each: shared brand and structure, with each platform's own navigation, controls and gestures.
Do you build the app too?
We design it and hand it over in a form developers can build from, and we stay on hand while they do. If you need a build partner, tell us on the kickoff call.
Can you redesign an app that's already live?
Yes. We start by watching people use the current version, then fix what trips them up first, so improvements ship in steps rather than one big bang.
How do you test the designs?
With a clickable prototype on real phones, with people who match your users, after each big design step.
What does it cost?
Fixed-price projects start at $1K, and a design team on a monthly retainer starts at $3K. One-off projects are 50% to start and 50% on launch.
Your team
The people you'll work with.
Real designers, a project manager who runs your timeline, and an account manager you can call. Our AI helpers handle the busywork so they can focus on the craft.
