Mobile App Development

Build a mobile app around your core business workflow, with the backend, admin tools and release preparation agreed in one scope.

// who it's for

You want to turn a product idea or an existing business service into an app for iOS, Android or both.

When this service helps

  • You need a first working app to put in front of customers.
  • Your customers or staff need mobile access to bookings, accounts, orders or a service.
  • You need an app connected to a new or existing backend and administration system.

How the work is delivered

  1. 1.Define the first release

    Clarify the target platforms, user journeys and essential features. Compare a mobile app with a responsive web app where either could meet the need.

  2. 2.Build the agreed product

    Implement screens, backend connections and agreed features such as authentication, notifications or payments. Review progress against the milestones.

  3. 3.Test and prepare release

    Test core flows on the agreed devices and prepare builds, configuration and release materials. Store submission support is specified in the quote.

What's included

  • User flows and agreed screen structure
  • iOS and/or Android development as scoped
  • Backend APIs and admin tools where included
  • Account, notification or payment integrations as agreed
  • Testing on an agreed device and OS matrix
  • Source code, setup instructions and release handover

Not included

  • App store account fees, hosting, API and other third-party charges
  • Guaranteed app store approval or ranking
  • Additional platforms or features outside the agreed scope

What to send with your inquiry

Explain who the app is for, the main task it should make easier, your target platforms and budget. Sketches, reference apps and existing API documentation are helpful.

Common questions

Should I build a mobile app or a web app?

We can compare your device needs, distribution, budget and ongoing maintenance. I recommend the simplest approach that meets the agreed requirements.

Can you build the backend too?

Yes. Backend APIs, a database and an admin panel can be included in the project scope rather than left as a separate dependency.

Can you help with launch?

Yes, where included in the quote. Store accounts remain yours, and acceptance depends on the platform review and your application requirements.

How do I pay?

Once you approve the written quote, I send a PayPal invoice. You can pay with a PayPal balance or a card through PayPal.
