App development in Cardiff

We design and build iPhone and Android apps for businesses in Cardiff — a city of roughly 370,000 people in Wales — from simple booking and loyalty apps to staff tools for teams on the move.

Our approach for Cardiff businesses is simple: we show you a clickable design of your app first, free of charge, then agree a fixed price for the build — no hourly billing surprises.

App ideas for Cardiff businesses

  • Driveway Specialists — Site diary & snagging: Your team records daily progress, issues and photos from site.
  • Landscapers — Job booking with photos: Customers describe the problem, add photos and pick a slot — you quote with the full picture.
  • Cafés — Offers for regulars: Quiet-time offers and new menu alerts.
  • Hairdressers — Loyalty rewards: Points or a stamp card for regular clients.
  • Painters & Decorators — Job booking with photos: Customers describe the problem, add photos and pick a slot — you quote with the full picture.
  • Bathroom Fitters — Consultation booking: Book an initial consultation and share photos of the space.

How an app project works for Cardiff businesses

  • Free discovery call — A relaxed 30–45 minute video call about your customers, what the app must do and what success looks like. No charge and no obligation.
  • Free design concept — We design key screens of your app and share a clickable prototype you can tap through on your own phone — free, with no commitment.
  • Fixed-price build — Agree a fixed-price quote and we build in short sprints, sending you test builds via TestFlight (iPhone) and Google Play internal testing (Android).
  • App Store & Google Play submission — We prepare store listings, screenshots, privacy details and submit to Apple and Google under your own developer accounts, handling any review feedback.
  • Care, updates & growth — Optional monthly care: OS updates, bug fixes, monitoring, hosting for your app’s back end and small improvements as your business grows.

iPhone, Android or both?

Most Cardiff businesses launch on both the App Store and Google Play. We usually recommend one cross-platform codebase to keep build and maintenance costs down, and go fully native only where the app genuinely needs it.

Across Cardiff, businesses with more than one location can share one app, with each branch managing its own bookings, menus or offers.

Frequently asked questions

Do you build apps for businesses in Cardiff?

Yes. We design and develop iOS and Android apps for businesses in Cardiff and across Wales. We work remotely by video call, phone and email, and you test every version on your own phone.

How much does an app cost for a Cardiff business?

Every app is different, so we don’t publish one price. After a free discovery call and a free design concept, we give you a fixed-price quote for the agreed scope — no hourly surprises. Starting prices for our discovery workshop and care plan are listed on our pricing page.

What do Apple and Google charge to publish an app?

At the time of writing, Apple’s Developer Program costs US$99 a year (billed in local currency) and Google Play charges a one-off US$25 registration fee. If you sell digital content inside the app, the stores take a commission — commonly 15% for smaller businesses on their reduced-rate programmes and 30% otherwise. Physical goods and real-world services, such as table bookings, haircuts or food orders, can usually take normal card payments instead. We check the current terms for your app before you commit.

Who owns the app and the code?

You do. Once the project is paid for, the source code and design files are yours, and the app is published under your own Apple and Google developer accounts. If you ever move to another developer, we hand everything over.
