Mobile App Development
Mobile App Development
We take a mobile product from idea to a real, working application — product design, architecture, development and the groundwork for launch.
A mobile app is a longer commitment than a website — the structure has to be right from the start. We plan the architecture before we write a line of interface code.
What this solves
- An idea for an app that's never been scoped into something buildable
- Uncertainty about what to build first versus what can wait
- A product with no clear technical architecture behind it
- A team that can design or code, but not both under one roof
What's included
Product Design
Screens and flows designed around how people will actually use the app.
UI / UX
Interfaces that stay clear on a small screen, not shrunk-down desktop design.
MVP Planning
Deciding what belongs in the first real version — and what doesn't yet.
Application Architecture
A structure built to support the app as it grows, not just the first release.
React Native Development
A single codebase built with React Native and TypeScript.
Testing & Launch Preparation
Checked against real devices before anything ships.
How we work
Discovery
Understand the goal, the users and what's already working.
Scope
Define what's in, what's out, and what success looks like.
Design
Interfaces and structure, tested against real content.
Build
Engineered and tested — no unfinished edges.
Launch
Shipped, measured, and ready to iterate.
Who this is for
- Founders with a mobile product idea that needs real scope
- Businesses extending an existing brand into a mobile app
- Teams validating a concept before a larger investment
- Companies replacing an outdated or unmaintainable app

DEVUDI works across strategy, design, development, growth and content — under one roof, with the people actually doing the work staying close to the project from the first call to launch.
Frequently asked questions
What technology do you build mobile apps with?
React Native with TypeScript — a single codebase that runs on both iOS and Android, which is also what our own in-progress products, RepFlow and YolKaça?, are built with.
Can you build native iOS and Android apps separately?
Our current architecture is React Native-based. If a project genuinely needs fully separate native codebases, we'll tell you honestly during scoping rather than after.
Do I need a finished design before we start development?
No — product design and development happen together at DEVUDI. We usually start from a rough idea and shape the design and the build in the same process.
Are RepFlow and YolKaça? already available to download?
Not yet — both are DEVUDI's own in-progress mobile products, currently marked Coming Soon. They're shown here as real examples of our mobile product work, not as claims of availability.
How do you decide what goes into the first version?
That's the MVP planning step — we work through what the app actually needs to be useful on day one, and what can reasonably wait for a later version.
