Questions people ask

What's the difference between a web app and a website?

A website mostly shows information. A web app is something people sign in to and use: they enter data, see it on a dashboard and work with it. Both open in a browser, so there's nothing to install.

Can you turn our spreadsheet into an app?

Yes. Send me the spreadsheet or a screenshot of it, and tell me who uses it and what goes wrong. The app is built around how your team actually works.

How long does it take to build a web app?

Ready within 31 days. You see a first working version within days, and two rounds of changes on it are included. A bigger app gets a later date in its fixed quote.

What do you build web apps with?

Usually Next.js, React and TypeScript, with Supabase for sign-in and data. It's the same set I used for Greater Than Services, which is live.

Who owns the code and the data?

You do. The code and the data are yours, and the accounts the app runs on are in your name, so another developer can take over later if you ever need one.

Can it take payments?

Yes. Greater Than Services, which I built and run, has sign-up, accounts and online payments. Your quote lists exactly what your app includes.

A clear scope before the build

Your quote confirms the pages or screens, features, content needed, running costs and delivery date. The date depends on receiving the agreed material and feedback on time. Two rounds of changes on the first version are included.

After full payment, the code, domain and accounts set up for you are yours. Fixes for work that does not match the agreement are covered for the first 14 days after launch. See the terms and use the project brief checklist to prepare your scope.
