App Development Company in London & the UK.
As an app development company in London, Control Shift builds iOS, Android, and cross-platform apps for startups, scale-ups, and enterprises across the UK. App development in London demands more than clean code — it needs GDPR compliance by design, Open Banking rails via TrueLayer, Plaid and Yapily, and, for regulated fintech, FCA-aligned architecture with PSD2 Strong Customer Authentication. As a mobile app development company serving the UK, we ship products with native UX review, GBP formatting, and audit-ready data processing. From a lean 4-week MVP to enterprise platforms for Manchester, Birmingham, and Edinburgh teams, we engineer to the standards the UK market expects — and hand you 100% of the source code, App Store accounts, and IP.

Common Questions
Mobile app development in London starts from £1,075 for our fixed MVP offer and scales up from there based on the complexity of regulated integrations (Open Banking, PSD2/SCA, GDPR-grade infrastructure) and feature scope. Every project gets a fixed, scoped quote before a line of code is written — dedicated team engagements are also available.
