    Questions

    Asked before most projects.

    How long does it take to build a custom web app?

    Timelines vary based on complexity. A simple app can be ready in 4–6 weeks, while a full platform with user accounts, dashboards, and integrations typically takes 8–12 weeks. We'll give you a clear timeline after our discovery call.

    How much does app development cost?

    Custom web apps typically start from £3,000 for a simple application. More complex platforms with multiple user roles, payment processing, and advanced features range from £5,000–£15,000+. We provide detailed, transparent quotes.

    What technologies do you use?

    We use modern web technologies including React, TypeScript, and cloud-based backends. This ensures your app is fast, secure, scalable, and easy to maintain long-term.

    Will I own the code?

    Yes, 100%. You own everything we build. The code, the design, the database — it's all yours. No lock-in, no ongoing licensing fees.

    Can you build mobile apps?

    We specialise in progressive web apps (PWAs) which work beautifully on mobile devices and can be installed like native apps — without the cost of separate iOS and Android development.

    Do you offer ongoing support after launch?

    Absolutely. We offer monthly maintenance packages that include bug fixes, feature updates, server monitoring, and priority support so your app keeps running smoothly.
