FAQ

Frequently asked questions

We only have an idea. Can we start?

Yes. Most projects start with an idea. The product design stage turns it into a feature list and roadmap before you commit to building the full app.

How long does an app take, and what does it cost?

It depends on the scope, which we agree before quoting. If budget is limited, you can start with an MVP that is still ready for real users.

Who owns the code and the accounts?

You do. The App Store, Google Play, server and code accounts are in your name from the start, not handed over later.

Do we have to stop using our spreadsheet straight away?

No. The new system runs alongside your current process until your team is confident. Your existing data is migrated, so nothing needs re-entering.
