How we work

From idea to your phone.

Four steps, no jargon. You tell us what you want, we build it, and you walk away with a real app.

  1. Tell us your idea

    What do you wish your phone could do? We'll hop on a free call to understand the problem and figure out if an app is the right answer.

  2. Design

    We map out every screen — either from your sketches or from scratch. You'll see a clickable prototype before any code is written.

  3. Build

    We build your app in React Native with regular check-ins so you can try it as it comes together. No surprises.

  4. It's yours

    We handle the App Store and Play Store submission. The finished app is yours — no subscriptions to us, no ads, no strings attached.

Pricing

Pay for what you actually need.

No hidden fees, no recurring charges to us. You pay for the screens and features you need — that's it.

Screen pricing — all tiers

Per screen — your designs $20
