Mobile app design agency for iOS and Android
We design iOS and Android apps that people keep opening, from a first MVP to apps with 300K+ users, and our developers can build the frontend too.
Designed apps for teams like
What we design
What a mobile app needs to get right.
A mobile app design agency designs more than screens. These are the parts we work through on every iOS and Android app, because they decide whether people stay.
Onboarding
The first minutes: value before sign-up, permissions asked when they make sense, and steps people can skip.
Navigation
Tab bars, sheets and back gestures that feel at home on iOS and Android, not a website squeezed onto a phone.
The core loop
The action people come back for, one tap from home, with feedback that makes it worth doing again.
Every state
Empty, loading, error and offline states, designed alongside the happy path instead of after it.
Roles
Players, coaches and parents, or travelers and local creators: each role gets its own path through one app.
The store page
Store screenshots that show the app in use, in the order people scroll, so the listing sells the download.
Inside an app
From the first flow to the app that ships.
What a mobile app design agency hands you, shown on three real apps. Pick one, then step down from the flow to what people see on their phones.
Players, coaches and parents shared one structure. We mapped the information architecture in two rounds, each role with its own front door.
What you keep
- Information architecture
- Role map
New users were dropping out of a long onboarding. It now opens with the sport, player details and a training path, then a demo before any account.
What you keep
- Onboarding flow
- Demo-first entry
Badge tiers, points and rewards in each of their states, so progress is something players can see and want to collect.
What you keep

How a mobile app project runs.
About 12 weeks from kickoff to handoff for a new app. Coloured bars are our work, grey ones are yours. Point at a step to see what you keep.
Week 1
- Kickoff You: One call on the app, the users, the goals and what your store reviews say.
- Access You: Test builds, analytics and the requests your support team hears most.
- App audit Research and UX: The live app or the idea, your users, the apps they compare you with and where people drop off.
Week 2
- User flows Research and UX: The core journeys, the roles, the navigation and how every screen connects.
Week 3
- Wireframes and prototype Research and UX: Grey screens for every state, linked into a clickable prototype you can try on a phone.
Week 4
- Flows OK You: You sign off the journeys, the navigation and the screen map, with your engineers on what each platform allows.
Week 5
- Visual direction UI design: Moodboards in two or three directions, to lock the look before every screen.
Week 6
- Prototype OK You: You tap through the grey prototype on a phone and sign off the structure.
- App UI UI design: Final screens for iOS and Android and every state, in light and dark where you need both.
Week 7
- Components UI design: A component library with variants: buttons, cards, sheets, navigation and the rest.
Week 8
- UI notes You: Your notes on each round of the final screens.
Week 9
- Store screens UI design: Store screenshots with one short line each and a real view of the app.
Week 10
- Handoff and QA Handoff and build: Organised files, every state documented, and a review of each test build.
Week 11
- Frontend build Handoff and build: Optional: our developers build the iOS and Android frontend with your team, as on Ballogy.
Week 12
- Handoff You: The Figma file, the components and the store screens are yours.

Questions on mobile app design
Still having more questions?
Send us your app, the flows that matter and what needs to change. We’ll help you map the right scope, team, timeline, and next steps.
What does a mobile app design agency do?
A mobile app design agency designs the app itself: the user flows, navigation, screens, states and components for iOS and Android, plus the store screenshots. DesignMe is a mobile app design agency for startups and scale-ups. We take an app from an audit or an idea to final screens and a developer-ready handoff, and our developers can build the frontend too.
Do you design for iOS and Android separately?
We design one app with one design system, then adapt what each platform expects: navigation, back behaviour, system controls, type and sizes, following Apple’s Human Interface Guidelines and Google’s Material Design. Ballogy and Hint both run on iOS and Android.
Are you an Android app design agency too?
Yes. Android apps get the same care as iOS: the system back gesture, Material patterns where they help, and layouts that hold up across the many screen sizes Android runs on.
Can you build the app as well?
Yes. On Ballogy, after 9+ months of redesign, our developers rebuilt the iOS and Android frontend alongside Ballogy’s engineering team in a focused 3-month engagement. If you have your own developers, we hand off the Figma file and review each test build.
How much does mobile app design cost?
A mobile app design project starts at $10,000: a focused redesign from $10k, a full app from $25k. Ongoing app design runs on the Design plan from $6,000 a month, with 10% off for funded startups. Not sure where to start? A UX audit ranks what to fix first in 3 to 5 days.
How long does it take to design a mobile app?
About 12 weeks from kickoff to handoff for a new app. TravelWith and N3XT went from an idea to the MVP in 3 months, and Zave.it went from first drafts to launch in 3 months. A focused redesign of a few flows takes less.
Can you redesign our app without losing users?
Yes. We keep what people already rely on and change the rest in stages. On Ballogy we shortened an onboarding that was losing new users and split one shared structure into player, coach and parent journeys. Their App Store rating went from 4.3 to 4.7.
Are you a custom app design agency, or do you use templates?
Custom. Every app is designed around its own users and flows, with its own component library, not a UI kit. That is why Zave.it, Hint and Ballogy look nothing alike.
Do you design App Store screenshots?
Yes. For Hint we designed the App Store screenshots in the order people scroll, each with one short line and a real view of the app. We can design them as part of any app project.
Do you design web apps too?
Yes. Most of our apps have a web version: ViaKonnect has 450+ web app screens next to its mobile app, and Hint’s web app carries the same maps to a bigger screen. For SaaS dashboards and complex web platforms, see product design.
