What happens after you write

  1. [ 01 ]

    We reply within 24 hours

    You get a real answer from the person who would build your product, with first questions and a suggested next step, not an autoresponder.

  2. [ 02 ]

    Free 30 minute discovery call

    We talk through your idea, users, and constraints. You leave with a clearer picture of scope and feasibility, whatever you decide next.

  3. [ 03 ]

    Fixed scope and price in writing

    You receive a written proposal with scope, timeline, milestones, and a fixed price. Not happy after milestone one? Walk away, owe nothing.

Booking, by us

Book us inside Frendex, the app we built

Frendex is our own local services booking app, live on the App Store and Google Play. Our studio keeps a provider profile in it, so you can book us the same way a Frendex user books a hairdresser or a plumber. It is the shortest way to see how we build, from the inside.

On a phone the link opens Frendex, or the store first if you do not have it yet.

Quick answers before you write

A few sentences are enough: what the product does, who it is for, the platforms you have in mind, and any deadline or budget range you already know. A one page brief is great, but not required. We will ask the right questions on the call.

Within 24 hours on business days, usually sooner. The reply comes from the person who would actually build your product, with concrete next steps.

After the discovery call you get a written proposal with a fixed scope and a fixed price, delivered in milestones. If you are not happy after the first milestone, you can walk away and owe nothing.

You do. On full payment, all rights to your product, its code, and its design assets transfer to you. No licensing carve-outs.

Both. The studio is based in Budapest (CET) and works with clients worldwide, with calls and documentation in English or Hungarian.

Cross-platform mobile apps built with Flutter, web apps on React and Astro, custom marketing sites, and AI features built into real products. If you are not sure your idea fits, ask: the discovery call exists exactly for that.

Launch is not the end of the engagement. We offer ongoing maintenance and growth work: bug fixes, OS and dependency updates, new features, and iteration guided by how real users behave in the product.
