Frequently Asked Questions
Clear answers to the questions we hear most from UK startups and business owners.
An MVP (Minimum Viable Product) is a focused, working first version of your app that includes only the essential features needed to validate your idea, attract users and test the market — without the cost and delay of building everything at once.
The Starter App includes up to 7 custom screens for iOS & Android, UI/UX design, secure login and cloud database, a basic admin dashboard, multi-device testing, App Store submission guidance, source-code handover after full payment, and two weeks of aftercare.
A typical Starter App takes approximately 2–3 weeks for suitable, clearly scoped projects after requirements, content, access and payment milestones are complete. Growth and Pro packages take longer. Final timing always depends on scope.
Yes. Source-code handover is included after full payment is received. You own the code and are free to take it to any developer in the future.
Absolutely. Every MVP is built on scalable foundations. You can add features, screens, integrations and user roles over time. New features and scope changes are quoted separately.
No. Apple App Store and Google Play developer account fees, third-party API costs (such as Stripe, push notification services or hosting) and any other external charges are separate and payable by you directly to the provider.
