Why Choose Us

Senior Flutter developers. Production-grade code.

The same team that built apps for Harvard Medical School, Intesa Sanpaolo, and Vodafone. 40+ apps shipped, 15+ years combined experience. We deliver real apps—not prototypes, not templates.

Unlike AI app builders, we don't generate code from prompts. Our senior engineers write production-grade Flutter—the same quality we delivered to enterprise clients. You get a real app that scales, not a demo.

Not sure if your idea will work?

Our honest advice: validate before you build. We don't want you to invest €8K on something that might not find its audience. We can help you test your idea with a landing page and real ads in 2 weeks. €1.500 — and if you decide to go ahead with the app, we'll credit €500 toward development.

Frequently asked questions

How does the process work?

We start with a call where you tell us your idea. We help you define the scope and shape your MVP—cutting what's not essential. Once aligned, we build and deliver in 3 weeks.

What if I need more than 10 screens?

We scope everything upfront. Extra screens can be quoted separately.

What tech stack do you use?

Flutter for the app, Supabase for backend, Firebase for push notifications.

Do I own the code?

100%. Full repository access, no lock-in.

What if Apple rejects the app?

We handle resubmissions. It's part of the service.

Can I add features later?

Yes. We offer feature sprints at €3.500/week.

• In-app payments: +€800 • User chat: +€2.500 • Booking system: +€1.800 • Reviews & ratings: +€600 • Advanced search: +€800 • Multi-language: +€600/lang • Admin dashboard: +€2.000 • Web version: +€3.500 • Custom design: +€2.500 • 2-week delivery: +€1.500 • Monthly support: €500/mo

What are the payment terms?

50% upfront to start, 50% on delivery. We accept bank transfer and credit card. No hidden fees.

What if the project takes longer than 3 weeks?

We scope carefully upfront. If delays happen on our side, we absorb the cost. If you request changes mid-project, we'll discuss timing and cost before proceeding.

How do we communicate during the project?

You get a dedicated Slack channel with direct access to your developer. Weekly video demos every Friday. No waiting days for replies.

What about updates after launch?

2 weeks of bug fixes included. After that, you can either maintain it yourself (you own the code) or get our monthly support package (€500/mo).
