WHAT TO LOOK FOR

How to spot the best app development agency.

1

Shipped apps, not wireframes

Ask for links to live apps in the App Store and Play Store. Check ratings, download counts, and crash-free rates. Wireframes and Figma mockups aren't evidence of shipping capability.

2

Platform expertise

The best agencies have genuine expertise in their recommended platform (Flutter, React Native, Swift, Kotlin) — not just theoretical knowledge. Ask about their last 5 shipped apps and what stack they used.

3

Compliance capability

For fintech (FCA, PCI-DSS), healthcare (NHS DSP), or regulated industries — ask for evidence of compliance experience, not just claims. Certifications (ISO 27001, Cyber Essentials) matter.

4

Fixed-scope, not time-and-materials

T&M billing incentivises scope creep. The best agencies quote fixed prices after a paid discovery week. If they can't give you a fixed price after understanding your requirements, they don't understand them well enough.

5

You own the code

Source code in your GitHub org from day one. Apple Developer and Google Play accounts in your name. If you part ways, you keep everything functional.

6

Post-launch support plan

Apps require ongoing maintenance: OS updates, security patches, bug fixes, feature iterations. The best agencies offer care plans and growth retainers.

MARKET CONTEXT

London's app development market is one of the densest in the world with 4,000+ companies. Typical costs: MVP £25,000-£60,000, production app £60,000-£150,000, complex platform £150,000+. The biggest risk is agencies that overpromise timelines — a 12-week MVP quoted at 6 weeks always ends up being 16 weeks. Fixed-scope pricing with weekly demos is the best protection.
