Questions people ask
How accurate is the app development cost calculator?
It gives a realistic range for work by a UK freelancer or small agency, built from the guide prices the VouchQuote team sets for each option. It cannot see the detail of your project, so treat it as a budget to plan with and get real quotes before you commit.
What are the lowest and highest estimates it can give?
With the simplest answers the estimate starts at £4,000 per project. With every option at its most demanding it reaches £67,000 per project. Most projects land well inside that.
Does where I live change the price?
Yes, a little. Choose your city and the estimate is scaled by that city’s price index. London is the highest, at 25% above the UK average. Many professionals work remotely, so you are not limited to local prices.
Do I need to sign up to use it?
No. The calculator is free and needs no account or email address. If you then want real quotes, you can post the job free and up to 3 checked professionals reply.
Should I pay a fixed price or hourly?
Fixed price with clear milestones protects you when the scope is well defined. Hourly suits evolving products. Ask for milestones in either case.
How much does it cost to build an app in the UK?
A focused first version usually falls in the lower half of the range above. Payments, bookings, admin dashboards and building for both iOS and Android each add to the cost.
