Flutter product builds
One codebase for iOS and Android. Used in production for consumer apps with auth, media, wallets, and push, not just demo screens.

We build the apps companies put in customers’ hands. One codebase, two stores, production habits.
Typical start
Discovery in week one
Build length
6–14 weeks for a serious v1
Best for
Consumer and operations apps
The problem
Hiring separate iOS and Android teams is slow and expensive. A cheap freelancer app usually looks fine in a screenshot and falls apart on payments, notifications, offline use, or the next OS update.
What you walk away with
You get a single product that ships to both stores, talks to a real backend, and is structured so the next feature is not a rewrite.
01
One codebase for iOS and Android. Used in production for consumer apps with auth, media, wallets, and push, not just demo screens.
02
If your engineers already think in React, React Native keeps the language and hiring pool aligned. We choose it on purpose, not by default.
03
Signing, store listings, push certificates, in-app purchases, Apple Pay / Google Pay, and the boring checklist that actually blocks launch.
04
The mobile UI is only half the product. We design the API, auth, and data model with the app, so you are not stitching two vendors together later.
Auth, the core job-to-be-done, push, and a first store listing. Flutter when both stores need to ship together.
Two audiences (customer and operator or driver), maps, status flows, and the API that keeps them in sync.
A mobile client on top of an existing web product, same accounts, same API, store-ready wrappers.
Step 01
We decide what ships in v1. Features that do not earn their place wait. This is how apps actually launch.
Step 02
Navigation, auth, offline, and the API contract are designed before screens multiply. You see the skeleton early.
Step 03
Each slice is usable: login, core job-to-be-done, payments, then polish. You can test on devices throughout, not only at the end.
Step 04
TestFlight / internal testing, store submission, crash reporting, and a release rhythm for the updates that come after launch.
What a company can put in a statement of work.
Ownership and handover are part of the professional standard.
How a company starts
You do not need a 20-page RFP. A messy but honest brief is enough for a scoped proposal.
Who uses the app, and the one job they must be able to finish
iOS, Android, or both, and whether a web admin is needed
Any existing API, Firebase, or codebase we should not ignore
Payments, chat, maps, or other features that change architecture
Store accounts: do you already have Apple and Google developer access?
Tools we actually ship with. We will work inside yours if that is the cheaper path.
Saying no is how companies know we are not selling everything.
Flutter when we want one polished UI across both stores and a tight timeline. React Native when your web product is already React and you want one talent pool. We will tell you which fits the product, not which is fashionable this quarter.
Yes. We start with a short technical read: architecture, store status, crash rate, and what is blocking the next release. Then we either stabilise it or tell you a rewrite is cheaper.
We prepare the builds, listings, and certificates. You keep the developer accounts, that is how ownership should sit. We walk you through submission and review replies.
Yes, that is a mobile revamp. We audit crashes, store status, and the API, then either stabilise or rebuild in Flutter or React Native. Care retainers are for apps that are already healthy.
A serious v1 is usually 6–14 weeks, not a weekend. That includes the API, auth, and store packaging. A five-screen demo with no backend is faster, and usually not what a company should ship.
Yes. An app without an API is a prototype. Auth, data, payments, and admin are part of the same engagement unless you already have a backend we can plug into.
