Where you stand

Three ways to get an app built, in 2026.

Each is legitimate depending on what you want to ship. Our offer sits in the middle.

€30 — 50k
Solo freelancer, AI-assisted
Ideal for quickly testing an idea, shipping a light prototype, validating a concept before fundraising.
Per your simulation
Senior studio — our offer
Ideal for building a reliable, maintainable and transferable foundation that should hold 3 years without crumbling.
€200 — 300k
Big Paris agency
Ideal for large accounts with heavy internal processes, formal contracts, teams of 8-10 people.
Our angle

A senior product studio. Augmented by AI.

AI saves time. Process makes sure that saved time doesn't turn into technical debt six months later.

We use AI like any senior dev in 2026 — seriously, reviewing every line, testing every assumption. What justifies studio pricing over freelance pricing is not the hours saved: it's the rigor of the process around it. Tests, architecture docs, code transferability, written warranty.

We're not the cheapest. We're not the most expensive either. We're the most reliable.

Frequently asked

What clients ask before they sign.

Plain English. The answers we give in discovery calls.

How much does a mobile app cost in 2026?

Between €12k and €200k+ depending on commitment level. Scoped prototype €12-25k, serious MVP €35-70k, scalable product €80-160k+. The simulator above calculates your specific case based on the platforms, modules, monetization, and design you choose.

What's the difference between a prototype and an MVP?

A prototype is for testing an idea or impressing investors: 3-5 screens, working demo, minimal docs, no systematic testing. An MVP is a real product in production with its first users: 8-15 screens, basic tests, 1-month post-launch warranty. A scalable product is designed to hold 3 years and handle load.

Native (Swift/Kotlin) or cross-platform (Flutter), which to choose?

Cross-platform Flutter for 80% of cases: one codebase for iOS + Android + Web + Desktop, performance equivalent to native for standard use, 30-40% cost savings. Native only for very specific needs (advanced 3D rendering, deep hardware integration, sub-frame latency).

Why a studio rather than a freelancer on Malt?

A freelancer ships code. A studio ships a product in production: design, dev, cloud infrastructure, tests, monitoring, CI/CD, post-launch warranty, transferability. At equivalent budget, the studio handles the whole ecosystem around the code. For a quick disposable MVP, hire a freelancer. For a product that needs to last 3 years, hire a studio.

How long does it take to build an app?

From 8 weeks for a scoped prototype to 24 weeks for a complex scalable product. The simulator displays the estimated timeline in the black sidebar, based on your configuration.

What happens after the estimate?

Free 30-minute discovery call to scope together. If we're the right team, we provide a detailed line-by-line quote. If we're not, we point you to someone better suited. No commitment before signature.

Are your prices negotiable?

Our ranges are what they are. But the scope is negotiable: we can reduce it to fit your budget, or expand it for more ambitious needs. Everything is transparent line by line.

What about AI in all this?

We use it seriously, like any senior dev in 2026. But what justifies studio pricing over freelance pricing is not AI itself — it's the process around it: tests, docs, thoughtful architecture, code review, written warranty. AI accelerates; process protects.

Which platforms do you cover?

iOS and Android (Flutter or native), Web (Flutter Web or Next.js with SEO), Desktop Windows/macOS/Linux (Flutter Desktop). In most cases, a single Flutter codebase covers everything.

What happens after delivery?

One month warranty included: any bug introduced before delivery is fixed at no extra cost for 30 days. Beyond that, we offer maintenance contracts (€600 to €2,500/month) that secure your app long-term.
