Why the number is real

Everyoneclaims“AI-powered”. Wecanshowyouthemachine.

The agencies bidding on this search all say the same three things: AI-assisted, UK-based, get a quote. Here is the part they cannot demo.

An AI App Builder, in production

Not a landing-page claim — a working build pipeline. We scaffold, iterate and preview your app with AI in the loop, which is why our day count comes in below a hand-coded shop's.

iOS + Android from one build

Cross-platform via Expo — one codebase, both stores. You are not paying two teams to build the same app twice, and that saving is already in the estimate above.

Shipped to the stores, not just handed over

App Store Connect and Google Play submission is part of the job — listings, screenshots, review. You get a live app on the stores, not a zip file and good luck.

How the estimate is built

Nomagic.Justdays× arealrate.

  1. Every feature carries a build-day count

    Payments is more days than push notifications. The figures next to each toggle are the real estimates we work from.

  2. Days are priced at a UK day-rate band

    Straightforward work sits at the low end, integration-heavy work at the high end — £150 to £600 a day depending on complexity.

  3. You see a range, not false precision

    Anyone quoting an exact figure before scoping is guessing. The range narrows to a fixed price once we have talked.

An app is worth building when it earns or saves more than it costs. If a build will not pay back, we would rather tell you before you commit than after.
