One codebase. iOS and Android. An MVP in 8–12 weeks.

Cross-platform (Flutter) and native (Swift/Kotlin) app development, scoped around a fast, focused MVP and built on architecture that doesn't need a rewrite six months in.

Why teams come to us

  • MVP delays from building two native codebases in parallel
  • Cross-platform inconsistency — iOS/Android drift in look and behavior
  • Poor UX driving day-7 retention below 20%
  • Post-launch technical debt that turns every new feature into a multi-week project

What's delivered

Flutter cross-platform delivery

One codebase, pixel-perfect on iOS and Android

Structured MVP-first roadmap

Core features scoped and shipped first; extras scheduled post-launch

Mobile UX engineered for retention

Proven onboarding and navigation patterns

Scalable architecture from day one

Clean, modular codebase built to extend, not rewrite

Delivery phases

01

Scope

Core features get separated from nice-to-haves; everything gets a place in the roadmap, but not everything ships in the MVP. This is where the 8–12 week window gets set against a specific, agreed feature list — not a vague one.

02

Design

Screens and flows get designed against the onboarding and retention patterns the app actually needs, not a generic template pulled from a component library. Existing brand assets, if supplied, get applied here rather than redesigned from scratch.

03

Build

Flutter delivers one codebase for both platforms; Firebase and any required integrations get wired in as the app takes shape. Builds land on real devices throughout, not just at the end, so issues surface while they're still cheap to fix.

04

Ship & support

Store submission, launch, and a defined support window to fix what real users surface in the first weeks — the gap between how an app behaves in testing and how it behaves with actual traffic.

More detail

Is this the right fit?
  • You need iOS and Android from one team, not two separate native builds running in parallel — every week one platform waits on the other is a week of runway spent on coordination, not product.
  • You're racing toward a fundable MVP, not committing to a five-year platform on day one. The goal is a working product a real user can hold, not a spec document.
  • Retention keeps slipping because onboarding was never actually designed — it just happened as a side effect of whatever screens got built first, and nobody has gone back to fix it.
  • Every new feature costs more than the last, because nothing was built to extend. A codebase that started as a prototype is now taxing every sprint that touches it.
  • You have a backend, an API, or an existing system the app needs to talk to, and you need a mobile team that can integrate cleanly rather than starting the backend conversation from zero.

Not the right fit if

  • A five-year enterprise platform with a dedicated in-house engineering org already scoping the architecture — that's a different engagement, not an MVP build.
  • A pure landing page or marketing site with no app logic behind it — that's Website Design & Development, not this.
  • A project with no product owner able to make scope calls during the build — an MVP moves fast because decisions don't sit in a queue.
What we need from you

A clear product vision and who the first users are

Scoping an MVP means deciding what ships now versus later — that decision needs a real target user in mind, not a hypothetical one.

Any existing brand guidelines or design assets

Existing brand work gets used as-is. Rebuilding a brand system that already exists just to have one built in-house wastes budget that should go toward the product.

Details of any backend, API or third-party system the app needs to talk to

Integration points are where estimates go wrong most often — knowing them up front is what keeps the 8–12 week window realistic instead of aspirational.

One decision-maker who can answer scope questions without a committee

An MVP timeline assumes same-week answers on scope calls. A multi-stakeholder sign-off process is the single most common cause of an MVP timeline slipping.

Tech, and why it's the right call

Flutter

One codebase renders pixel-perfect on iOS and Android, instead of maintaining two native builds in parallel. For an MVP, that difference is the gap between an 8-week timeline and a 14-week one.

Firebase

Real-time data sync and a managed backend remove the need to stand up and operate custom server infrastructure before there's even a user to serve. It scales past MVP stage without a rebuild.

Stripe

Handles payment end to end, tuned for a mobile-first checkout rather than a bolted-on web flow ported into an app shell — the difference shows up directly in checkout completion rates.

On-device testing throughout

Builds land on real iOS and Android hardware from early in the build, not just at the end — the gap between how something behaves in a simulator and how it behaves in someone's hand is where most late-stage surprises come from.

Guides

FAQ

How long does it actually take?
A focused MVP typically ships in 8–12 weeks from kickoff — core features scoped and built first, extras scheduled after launch.
Do you build iOS and Android separately?
No — Flutter delivers one codebase that's pixel-perfect on both platforms, which is what keeps the timeline and cost down versus two native builds running on separate tracks.
What if I already have a designer or brand guidelines?
Bring them. Existing brand assets get used as-is in the design phase; there's no requirement to redo work that's already done, and no reason to pay for it twice.
What happens after launch?
A defined support window covers what real users surface in the first weeks — the gap between test behavior and production behavior. The architecture is built to extend afterward, not to need a rewrite for the next feature.
Can you integrate with a backend or API we already have?
Yes — that's exactly what the scoping phase is for. The clearer the integration details going in, the more reliable the 8–12 week estimate stays.
What does it cost?
Pricing depends on scope, so it isn't published as a flat number here — the free technical consultation exists specifically to size the work and give a real estimate before anything is committed to.
What happens if we need to change scope partway through?
Scope changes get discussed against the current phase, not silently absorbed — the 8–12 week window holds for the agreed feature list, and a real scope change gets a real conversation about the new timeline, not an unspoken slip.
