App development in Greenisland

Whether you run a salon, café, gym, clinic or trade business in Greenisland, Mid and East Antrim, an app puts you on your customers’ home screen — somewhere a website can’t reach on its own.

You see your app before you commit: a free design concept, then a fixed-price quote for iOS, Android or both.

How an app project works for Greenisland 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?

Customers in Greenisland, like the rest of the UK, use a mix of iPhones and Android phones, so most local businesses need their app on both. A cross-platform build with React Native or Flutter usually gives the best value; native Swift or Kotlin makes sense for specialist features.

In a smaller community like Greenisland, a light, affordable app — bookings, reminders or a loyalty card — is often all a business needs.

Frequently asked questions

Do you build apps for businesses in Greenisland?

Yes. We design and develop iOS and Android apps for businesses in Greenisland and across Mid and East Antrim. 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 Greenisland 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.
