Mobile App Development in the UK

For most business-to-business services supplied from outside the UK, the reverse charge applies: you account for the VAT in your own return rather than paying it to us, and it is typically neutral if you are fully recoverable. Our invoices state the position clearly so your accountant is not guessing. If your situation is unusual, for example partial exemption, we would rather your accountant confirms the treatment before we invoice than after.

We build to it rather than claiming a certificate. In practice that means data minimisation designed in rather than bolted on, a documented lawful basis for each processing activity, retention periods that actually delete, subject access and erasure handled as features rather than manual database work, and hosting in a region you approve. Where we process personal data on your behalf we sign a processor agreement setting out exactly that.

Yes, and it is scoped from the start because retrofitting accessibility is considerably more expensive than building it in. We work to WCAG 2.2 AA, test with a screen reader rather than relying on an automated scan, and produce the accessibility statement the regulations require. Automated tools catch perhaps a third of real issues, which is why the manual pass is not optional.

We are happy to contract under English law with the courts of England and Wales, and most UK clients prefer that. IR35 does not apply to us: it governs individuals working through an intermediary, and you are engaging a company for a defined deliverable rather than a person for their time. Your accountant will want to see that the contract reflects that, and ours does.

Flutter if your UI is custom and you want it to look and behave identically on iOS and Android from one codebase; it is what we used for both Jai Shri Balaji apps. React Native if you already have a React web team or depend on JavaScript libraries, because the skills and some code transfer. For most first apps we lean Flutter. On our call we pick based on your team and your UI, not a house preference.

We build cross-platform in Flutter or React Native, which compile to real native iOS and Android apps from a single codebase. For the vast majority of business apps that is the right call: one team, one codebase, both platforms, lower cost. We are not the right studio if you specifically need fully separate Swift and Kotlin native codebases or a heavy native game engine.

Yes, end to end. That includes developer account setup if you do not have one, app signing, store listings, screenshots, privacy and data-safety declarations, and the review back-and-forth with Apple and Google. First submissions often get bounced for small reasons, and we handle that so your launch does not slip.

A flat quote against a written scope, never an hourly meter. Send us the brief, we write the scope, and you get back one flat INR number, with the exact figure inside 24 hours. If you have a foreign parent company, we can invoice that entity in USD. What moves the number is how many screens, integrations, and platforms you actually need, not a clock.

It depends on the build, so the real timeline goes in the written scope rather than a stock number here. We work in short sprints with a working build at the end of each, so you see progress the whole way instead of waiting months for a big reveal. The backend and the integrations, not the number of screens, are what move a timeline most.
