We design and build
apps and websites
that earn their keep.

It depends entirely on scope, so we quote rather than list prices. A small marketing site is a different order of cost to a native app with accounts, payments and a backend. Tell us what you have in mind and you'll get a written quote with a fixed price before any work starts.

A straightforward website is usually two to four weeks. A first version of a native app is typically eight to sixteen weeks, depending on how much it has to do. We'll give you a date with the quote and tell you early if anything threatens it.

You do. The repository, the App Store listing, the domain and the hosting all sit in your own accounts from the start, not ours. If you ever want to take the work in-house or move to another studio, there's nothing to untangle.

Yes — both, and we're equally happy on either. Most clients launch on both platforms together; where a budget only stretches to one for now, we'll look at where your users actually are and tell you honestly which to start with. That's a decision about your audience, not a preference of ours.

Often, yes. We'll review the existing code first and tell you plainly whether it's worth continuing or whether rebuilding is cheaper in the long run — including when the honest answer is that you don't need us.

Every build includes a support window after release for anything that surfaces once real users arrive. Beyond that, most clients move onto a monthly arrangement for updates and new features — but it's optional, never a condition of the build.

Yes — Zero Horizon Ltd is registered in the United Kingdom, and we invoice in pounds. We work with clients outside the UK too; most of the work happens over calls and shared builds either way.
