iOS · Android · Mac · Windows · Web

Apps built by a team that runs its own.

We design, code, publish and support apps for iOS and Android from a single Flutter codebase, and we run the server behind them too. Stone Project, our software for stone fabricators, is live on iOS, Android, Mac, Windows and the web.

DMS.S2 — What's included

From first sketch to the app stores.

Turn a React web app into mobile apps

We review your existing web app and scope the work needed to deliver practical iOS and Android experiences, not just a website shortcut.

Backend and AI integrations

We can build the server-side accounts, API connections and credit logic your app needs, keeping private provider keys off the device.

In-app credits and digital products

When your app sells credits or digital items, we can implement the purchase flow for Apple and Google and connect it to the agreed backend.

One codebase, more platforms

For new projects, Flutter can ship to iPhone, Android, desktop and the web from one codebase.

Store publishing handled

Store listings, screenshots, review submissions and updates on the App Store, Google Play and the Microsoft Store.

Made for people on site

Quotes, photos and job records on the phone, for crews and owners who work in the field, not at a desk.

DMS.S3 — Existing React app

From web product to mobile app.

We scope the existing code before committing to a final price. Requesting a quote is free.

DMS.S5 — How we work

Every job starts on the drafting table.

Four steps, no shortcuts, and you approve the plan before any code.

01 / 04

Draft

Goals, sitemap, copy, and a design system on paper before a single line of code. You see the plan and approve it — like a blueprint.

02 / 04

Build

Hand-written code, reviewed and tested until it's fast on a job-site phone with two bars of signal.

03 / 04

Launch

DNS, SSL, analytics, and search indexing handled end to end. You get a checklist, not a surprise.

04 / 04

Care

We host, monitor, back up, and update — for years. When you call, the person who built your site picks up.

DMS.S7 — Questions

What people ask before a quote.

Do you build for both iPhone and Android?

Yes. We build in Flutter, so one codebase ships to iOS and Android, and to Mac, Windows and the web when the project needs it. Stone Project runs on all five.

Can you turn my existing React web app into an iOS and Android app?

Yes. We review the existing app and scope its mobile delivery, backend needs, protected AI API integration, account and credit features, and in-app purchases for Apple and Google. Projects start at $4,997. The exact scope and price are confirmed in writing after an NDA and technical review. Requesting a quote is free.

Do you need my source code to give me a quote?

No source code or credentials are needed to request a quote. We sign an NDA before asking for private repository access. Never send passwords, API keys or signing keys in the form.

Are hosting, AI usage and monthly updates included?

No. Server hosting and AI provider usage are billed separately based on the agreed setup and actual usage. Monthly store releases are available separately through App Store Publishing & Care.

Who publishes the app to the App Store and Google Play?

We do. We prepare the store listings and screenshots, send the builds for review and publish the updates. Our App Store Publishing & Care plan includes one release request per month for an existing app across the selected stores.

Can the app sell subscriptions?

Yes. Our own apps sell subscriptions inside the App Store and Google Play.

Do I need a website too?

Usually yes. People find the app through a page on Google, and the stores ask for a privacy policy and a support page. We build both in the same project.

What happens after launch?

We host and monitor the backend. For existing apps, our separate App Store Publishing & Care plan handles one store release request per month, with a changelog and submission follow-up.
