Choose between
A new app or a redesign. Same Team Throughout.
Redesign an existing app
We audit the flows people actually use, find where they drop out, then rework navigation, screens and states without throwing away what already works.
Design a new app
Product discovery and user flows come first, then wireframes, custom UI, a Figma design system and prototypes your engineers can build from.
Design system
Already shipping? We build the component library, tokens and variants your team reuses, so the twentieth screen costs a fraction of the first.

Tools we use
We design in Figma and hand the approved system to Claude and Cursor through Figma’s MCP server, so key flows become coded prototypes in Expo or Flutter on your own phone, tested with Maze, Stark and Maestro before engineers ship.

Frequently asked questions
Straight Answers. No fluff.
How long does it take to design a mobile app?
Four to six weeks for a focused app, from flows to engineering handoff. The number of flows, how much research is needed and whether you need both iOS and Android all move that. On the scoping call we will tell you which timeline your project fits.
How much does mobile app design cost?
Fixed-scope projects start at $1,500, and the final number depends on scope. What moves it: how many flows and screens you need, whether it is one platform or both, how much research is involved, and whether you want a design system your team can extend. We contract in USD.
Do you design for both iOS and Android?
Yes. We follow each platform's conventions for navigation, gestures and system components rather than stretching one layout across both. Where budget is tight we start with the platform your users are on and design the second from the same system.
Do you build the app as well, or only design it?
Design is what we do here. We hand off to your iOS and Android engineers with assets at every density, the native component named for each control and the edge cases written down, and we stay on through design QA so the build matches the screens. If you also need the app built, that is a separate conversation.
Can you work inside an app that is already in the stores?
Yes, and we often do. We work in your Figma, follow the tokens you already have and match the native patterns already in the build, so new screens ship in the same release as the old ones instead of looking bolted on.
What do your engineers actually receive?
A Figma file with flows, screens and states for both platforms, a component library with tokens and variants, prototypes that run on a device, assets exported at every density, and written notes covering the edge cases. Nobody should have to measure by eye.
Who owns the design files?
You do. Everything lives in your Figma from the first file, IP is assigned to you, and the flows, components and prototypes stay with your team once the engagement ends.
Can a US company work smoothly with a team in India?
Yes. We work in your time zone, so feedback turns around in hours rather than overnight. Contracts are in USD, IP is assigned to you, and MSAs and NDAs follow the terms US companies expect. The designers on your app stay on it from the first screen to the store release.
