App Development by Senior Developers

Looking to have an app built? We are 010 Coding Collective, a senior development studio building mobile apps, web apps, and progressive web apps. We work with senior developers and AI tools, so you get an app that holds up under real users, faster and at a sharper price.

Already vibe-coded your app with Cursor, Lovable, or ChatGPT? We build on top of it or take it over through managed development. Want to be sure your existing code is safe to scale first? Start with a vibe coding audit. After a broader software project than an app alone? See custom software development. And if you are nearby, you can also come by in Rotterdam.

Native, web app, or PWA: what fits you

Most agencies sell you a native app right away. We start with an honest question: what do your users actually need? For many business apps a web app or PWA is faster to launch, cheaper to maintain, and easier to update. We reserve native for the cases where it genuinely adds something.

🌐

Web application

Runs in the browser, on any device, without installation. Ideal for dashboards, portals, and tools where people work on both desktop and mobile. You roll out an update once, for everyone.

📲

Progressive web app (PWA)

A web app you install on your phone like a real app, with an icon on your screen, offline use, and push notifications. For most business apps this is the smart middle ground: the feel of an app without the cost and app-store procedures of native.

📱

Native app

Built for iOS and Android, with full access to camera, sensors, offline storage, and the app stores. We build native cross-platform with React Native, from one codebase for both platforms, which keeps costs lower than running two separate teams. The right choice when you genuinely use that hardware or want to be found through the App Store.

What we build

From a first version to an app used every day:

Mobile apps for iOS and Android, cross-platform with React Native
Web apps and PWAs that work on any device and can be updated instantly
MVPs to test your idea quickly with real users before you invest big
Finishing AI-coded apps you started with Cursor, Lovable, or ChatGPT
Integrations with the systems you already use, like CRM, payment providers, and APIs
Further development and maintenance of an app that is already live

From idea to the store

Our approach is built to get something working in your hands quickly, and then to expand it deliberately.

Intro and form

We talk through what your app needs to do and for whom. Based on that we advise on the form: native, web app, or PWA. So you start with the route that fits your users and budget.

Design and MVP

We design the core screens and build a first working version with only the features that matter. You put it in front of real users early, so you learn before investing big.

Build and integrate

We build the app out with senior developers and AI tools, and connect it to the systems you already use. Security and performance sit in the design from the start.

Launch and store

We take the app to production and, if it is a native app, to the App Store and Google Play. We handle the submission and guide the first release.

Maintenance and growth

After launch we stay involved. Updates, new features, hosting, and monitoring continue with the same team, so the app keeps growing with your users.

Frequently Asked Questions

What does it cost to have an app built?

That depends on the form and the features. An MVP or first version is usually a good deal lower than a full app with integrations, user management, and a native version for iOS and Android. In a free intro session we look at what your app needs to do and sketch out realistically what it costs and how long it takes. Because we combine senior developers with AI tools, we often price sharper than a traditional app agency.

Do I need a native app or is a web app enough?

For many business apps a web app or progressive web app is the smart choice: it runs on any device, is faster to launch, and easier to maintain. A native app is the right route when you genuinely need access to camera, sensors, or offline storage, or when you want to be found through the App Store. In the intro session we advise which form fits your users and budget, before a single line of code is written.

How long does it take to have an app built?

A working MVP often ships within a few weeks. A full app with integrations, user management, and a store release takes longer, depending on scope. Because we work with AI tools, there is often something working sooner than at a traditional agency. We set the exact timeline together after the intro session.

Can you put my app on the App Store and Google Play?

Yes. For native apps we handle submission to the App Store and Google Play and guide the first release. We account for the requirements of both stores in the design already, so you do not hit surprises at submission.

Can you finish our app built with Lovable or Cursor?

Yes. Many clients have already vibe-coded their app and want to bring it to production. We review what holds up and what needs attention, make the app secure and scalable, and can then take over hosting and further development. For a standalone review up front we have a separate vibe coding audit.

Do you maintain the app after launch?

Yes. An app is never finished at launch. Updates, new features, security patches, and hosting continue with the same team that built the app. So you never have to find a new partner halfway through, and the app keeps growing with your users.
