These guys know their work. Not my first time working with Luka and his flutter team, and frankly, I cannot complain about anything about mobile app.

Implemented features into my Flutter app with ease, and high attention to details. I worked with Luka and his team for maybe the 10th time, and they never disappoint. Recommended!

FAQ
How much does an app cost?
It depends on what you're building. Most first apps land between $5K and $30K. The price comes down to features, screens, and backend work. We give you a fixed quote before any work starts, so there are no surprises.
How long will it take?
Most apps take 6 to 12 weeks. A simple app can be faster, a complex one takes longer. After our first call, we give you a clear timeline with milestones so you always know where things stand.
How do I get a quote?
Message us "APP" and tell us a bit about your idea. We'll ask a few questions, then send you a fixed price and timeline if we have enough info. Otherwise, we'll send a scheduling link for quick free consultation. No cost, no pressure.
What tech do you build with?
We build with React Native so your app runs on both iOS and Android from one codebase. That saves you time and money. For the backend we pick the right tools for your project and explain why in plain words.
I have an idea but I'm not technical. Can you still help?
Yes. That's who we work with most. You bring the industry knowledge, we handle the tech. We help you figure out what to build, what to skip, and what it should really cost, before you spend a dollar.
How do you approach building an app?
We start with a call to understand your goal. Then we map out the app and give you a blueprint. You approve it, then we build, test, and ship to the app stores. You see progress the whole way, not just at the end.
Do I own the app and the code?
Yes, 100%. You get full source code and full IP transfer at close. We also sign an NDA before we even talk. Your idea and your app are yours, always.
Do you offer maintenance after launch?
Yes. Apps need updates as phones and app stores change. We offer maintenance plans to keep yours running smooth, and we're here for new features whenever you're ready to grow.
What if something breaks after launch?
We back our work with a 30 day guarantee. If a bug shows up that's on us, we fix it free. You're not left on your own after we ship.
Will you stick with me long term, or am I on my own afterwards?
We stick around. Most of our clients come back for updates and new features. Think of us as your tech team, not a one-time job. We're in your corner for the long run.

Really glad I found Luka for this. I needed a code review on an existing iOS app — not a new build — and he handled it without hesitation. The report was thorough and honest, especially around the AI recommendation layer which was my biggest concern. Clear priority list of what needs fixing and what can wait. Worth every dollar.
