App Development Cost Calculator UK: A Quick Snapshot

Here’s a general cost breakdown of building apps in the UK in 2025:

App Type	Estimated Cost (GBP)	Timeframe
Basic App (MVP, minimal features)	£8,000 – £20,000	1–3 months
Medium App (custom UI/UX, 3rd-party integrations)	£25,000 – £60,000	3–6 months
Complex App (AI, fintech, healthcare, AR/VR)	£70,000 – £200,000+	6–12 months

Factors That Determine App Development Costs in the UK

To understand the true cost of app development in the UK, let’s explore the major factors:

1. App Complexity

Basic apps: To-do lists, calculators, or news apps with simple features → £8k–£20k

Medium complexity apps: Booking platforms, food delivery, eCommerce → £25k–£60k

High-end apps: Fintech, healthcare, gaming, AI/AR apps → £70k–£200k+

👉 Example: A local restaurant app with menu browsing & payments may cost £15k, but an Uber-style app with real-time tracking could exceed £80k.

2. Features & Functionality

Every feature you add has a cost implication. For instance:

• Login & Authentication → £1,000 – £4,000
• Push Notifications → £800 – £3,000
• In-app Payments → £3,000 – £8,000
• Geolocation Tracking → £5,000 – £15,000
• Real-time Chat & Video → £7,000 – £20,000
• AI/ML Recommendation System → £10,000 – £30,000

👉 Example: An eCommerce app with product catalogs, payment integration, and live chat will cost significantly more than a static information app.

3. Platform Choice (iOS vs Android vs Cross-platform)

iOS only app – Slightly cheaper, but limited to iPhone/iPad users.

Android only app – Wider audience, but more device variations = more testing time.

Cross-platform apps (Flutter, React Native) – Save up to 40% of costs by building one codebase for both iOS and Android.

4. Development Team Costs

The cost of hiring app developers depends on who you hire:

• Freelancers in the UK: £20–£60/hr
• UK Agencies: £60–£120/hr
• Offshore developers (India, Eastern Europe): £20–£50/hr

👉 A London-based agency will cost much more than hiring a skilled offshore team, but may provide better on-site collaboration.

5. UI/UX Design

User experience can make or break your app:

• Basic UI → £2,000 – £5,000
• Advanced UI with animations & custom design → £8,000 – £20,000

6. Maintenance & Upgrades

After launch, don’t forget ongoing costs:

• Bug fixes, updates → 15–20% of total development cost per year
• Server & cloud hosting → £100 – £1,000 per month
• Security updates & scalability costs
