A What's Included

Everything we deliver,
included in a single fixed price.

No bolt-ons, no surprise invoices, no hidden milestones. Each capability below is in the Statement of Work you sign before any hour is billed.

01
Flutter & Dart
Modern Flutter (3.x), null-safe Dart, Riverpod or Bloc for state. Tested architecture, not a tutorial codebase.
02
Firebase backend
Auth, Firestore, Cloud Functions, FCM push, Remote Config. Or your existing API — we integrate either way.
03
Native parity
Platform-aware UI: Cupertino on iOS, Material on Android. Custom animations and transitions where they matter.
04
App Store & Play submission
We handle the listing, screenshots, store copy, review responses. You receive logins and ownership at launch.
05
Push, analytics, crash reporting
FCM push, Firebase Analytics, Crashlytics — configured before launch, not after the first crash.
06
CI/CD
Codemagic or GitHub Actions pipeline. Internal testing, beta channel, production builds.
B How We Work

Phased delivery with
weekly progress demos.

Every Friday you see what shipped this week on a private staging URL. No long silences, no end-of-project surprises.

01

Discovery & spec

A week of conversation. Feature list, user flows, data model, edge cases. You receive a written technical brief and fixed quote.

Week 1
02

Design

Figma for every screen and state, both platforms. You approve before we open Flutter.

Weeks 1–3
03

Build

Two-week sprints with a working build at the end of each. TestFlight and internal Android testing throughout.

Weeks 3–10
04

Submit & launch

App Store and Play submissions, listings, screenshots, copy. We handle the back-and-forth with reviewers.

Weeks 10–12
C Common Questions

Direct answers to what most clients ask.

Don’t see your question? Open the chat — usually a same-day reply.

One codebase, two platforms. About 40% less time and cost than building Swift + Kotlin separately. For most non-game apps, the native difference is unnoticeable.
Yes. On final payment, the entire repository (and Firebase project, and store listings) transfers to your accounts. You can fire us tomorrow.
Optional retainer from $1,200/month for bug fixes, new features, OS compatibility updates. Or pay-as-you-go for ad-hoc work.
Yes — but Flutter still makes sense even for one platform. You get a future-proof codebase if you ever decide to expand.
