I will develop your mobile app mvp in flutter for ios and android

About this gig
You have an idea. What you don't have is six months and $40,000 to find out whether anyone wants it.
Most apps don't fail because the code was bad. They fail because nobody tested the idea before building the whole thing. I build you the smallest version that still proves the point: one core feature that works, an onboarding that explains it, and a paywall that tells you whether people will pay. That's a real business answer, in weeks.
THIS IS FOR YOU IF
- You want to know if the idea sells before you commit a real budget to it
- You need something live to show investors, partners or an audience
- You've been quoted $30k and half a year and it doesn't fit your reality
- You tried a freelancer before and got a half-finished build you can't ship
- You need to be in the stores by a specific date and can't afford surprises
WHY ME
I run my own subscription apps, not just client projects. I know what converts on the first screen, what Apple sends back, and which features can safely wait for version two.
WHAT HAPPENS NEXT
Send me a few sentences about your idea. I'll come back with scope, timeline and a fixed price and I'll tell you honestly if the budget doesn't match the plan.

I build mobile apps end to end — from idea to a live app in the stores.
12+ years in mobile development: Flutter, native iOS and Android, backend APIs and admin panels. I've shipped 150+ apps, including my own subscription products, so I know what actually works after launch, not just how to write code.
Every project I deliver includes UI design and full QA testing, so you get a finished product, not a build you have to fix yourself.
I reply within a few hours and I'll tell you honestly if your idea needs a smaller scope.
FAQ
I have an idea but no spec or designs. Can you still start?
Yes. Send me a few sentences about the idea and who it is for. I turn that into a feature list and a fixed scope before any code is written, so you know exactly what you are paying for and when it lands.
Why Flutter and not native iOS and Android?
One codebase ships to both stores, so you pay once instead of twice and every update lands on both platforms at the same time. For most MVPs performance is the same as native. If your idea needs heavy native work, I will say so upfront.
Do I own the source code?
Yes. Full ownership, no lock-in and no licence fees. Source code is included in Standard and Premium, and available as an extra on Basic. You also get the repository and build instructions so any developer can pick it up later.
Do you publish the app to the App Store and Google Play?
Yes. I prepare the store listing, screenshots and metadata, submit the build and handle any review feedback until the app is live. The developer accounts stay in your name, so you keep full control of your own app.
What happens if Apple rejects the app?
I fix it and resubmit at no extra cost. After 150+ apps through review, most rejection reasons are predictable, so I design around them from the start instead of discovering them at submission.
Can you set up subscriptions or in-app purchases?
Yes, and this is where most MVPs leak money. I set up RevenueCat or Adapty, build the paywall, wire the store products and test the full purchase, restore and cancel flow in sandbox before launch, so your revenue tracking is correct from day one.
Do you design the app, or do I need my own designer?
Design is included in Standard and Premium. If you already have Figma files I build straight from them. If you have nothing, I design the screens with you first, so you approve how it looks before anything is coded.
How often will I see progress?
Every few days you get a build you can install on your own phone, not a status message. You see the real app taking shape from the first week, so there are no surprises on delivery day and course corrections cost nothing.
What support do I get after delivery?
You get the source code, build instructions and a walkthrough so you are never dependent on me. Bugs in what I delivered are fixed free. For new features or a next version, message me and we scope it as a new order.
