Flutter mobile app delivery with UX design and QA

If you have a web product, a backend, or nothing shipped yet, and no iOS and Android engineers, no mobile designer, no QA practice for store releases. Or your engineers are fully booked on the core product and a mobile sprint would kill a quarter of feature work. Either way: you need a team that takes the app from zero to App Store and Play Store — design and QA included.

Specific situations we see:

• Every mobile-build quote assumes you'll handle design and QA in-house.

• Your web product is winning customers who keep asking "is there an app?"

• A mobile build started with a freelancer is stuck: no QA process, no design system, no clean path to a store release.

• Your engineers are fully booked, so a mobile build waits two quarters on internal staffing.

Not the right fit if:

• You're cost-comparing against €25/hr offshore. We don't compete there.

• You've already chosen React Native or want native iOS / Android (Swift, Kotlin, Objective-C, Java). We ship Flutter.

• You want a single freelancer on an hourly rate. Full Team is the offer; for one embedded engineer, see our Single Engineer listing.

What you get

A Full Team that ships the mobile app end-to-end. Five deliverables:

• Flutter app development on iOS and Android from a single codebase. Production delivery from a senior + mid + junior engineering team. Flutter is on our canonical stack.

• Dedicated design. UX and UI handled by designers on the team — not delegated back to your side, not subcontracted. Part of the Full Team scope.

• QA included. Testing, release readiness, and store-submission discipline owned by QA engineers on the team. Part of the Full Team scope, not subcontracted.

• Backend extensions when needed (optional). If the app needs a new .NET / Azure backend or changes to an existing one, the same team builds it. Same flat rate, same delivery ownership.

• Ongoing engineering after launch. Feature work, store releases, bug fixes. The team stays on past the first ship.

Not included

• Native iOS / Android development (Swift, Kotlin, Objective-C, Java). We ship Flutter.

• React Native. We ship Flutter on mobile, not React Native.

• App Store / Play Store listing optimization, ASO, paid acquisition, screenshots, store positioning copy. That stays with your marketing team.

• L1 helpdesk, 24/7 on-call, user support, password resets.

• Commercial device-farm subscriptions. QA runs on real devices; renting a third-party device cloud is not in the offer.

Pricing & commercial terms

All rates are EUR, per developer, per hour. One blended rate across seniorities — you don't pay a senior premium when the senior is on the call.

Full Team — €50/hr per developer, blended, 4-month minimum. Senior + mid + junior + design/QA as needed, with delivery ownership. This is the rate before any long-term commitment.

Team Long Term — CUSTOM, 12-month minimum. The same Full Team on a year-long commitment, at a reduced per-developer rate with tailored guardrails. Once you've seen the team ship and you're ready to commit to a year, the rate comes down and stays down. It's where the long-running clients land.

One flat rate. No hidden fees. EU-based, CET timezone, English fluent across the team. We're a partner, not a body shop — the flat per-developer rate kills negotiation games, and the long-term tier is where it works hardest for you.

FAQ

Why a 4-month minimum?

Anything shorter and the integration cost eats the value for both sides. The minimum protects your investment, not ours.

Can you do design only, or QA only?

The Full Team tier is the offer — engineering, design, and QA together with delivery ownership. We can offer design or QA separately if needed.

Why Flutter and not React Native?

Flutter is on our canonical stack. React Native is not. If your team has chosen React Native, we're not the right fit.

You're more expensive than offshore.

We don't compete with €25/hr offshore. If that's your benchmark, we're not a fit.

What about the backend?

If the app needs a new .NET / Azure backend or extensions to an existing one, the same team builds it — without bringing in a second vendor. Flutter mobile, design, and QA stay the headline.
