An app developer whose apps are actually on the stores.

Writing an app is the predictable half. The half that catches people out is everything Apple and Google require before a listing goes live and keep requiring afterwards: account deletion and data export in the app itself, privacy labels that match what the software really collects, permission strings that explain themselves, age ratings, and a review queue that can hold a build for a fortnight with no explanation.

We have done it repeatedly, including the unglamorous parts: a build sitting in Waiting for Review for thirteen days, signing certificates, and shipping an update that reaches phones the same day rather than waiting for another review cycle. That experience is most of what you are buying, and it is why the first submission is the one that goes smoothly.

We build both platforms from one codebase, so a change lands on iPhone and Android together rather than being written, tested and paid for twice. Where a web version makes sense we ship that from the same code too, which is how GrowthSync runs as a website, an iOS app and an Android app at once.

The trade-off is honest: an app whose entire point is a platform-specific capability is sometimes better written natively, and we will say so rather than sell you the thing we prefer building. What decides it is what the app has to do, not what is convenient at this end.

Accounts and roles, so what a person can do depends on who they are rather than which link they were sent. Push notifications that reach a phone instead of an inbox nobody opens. Payments that reconcile against the thing that was bought. Offline tolerance, because your users are in a car park with one bar of signal, not at a desk on fibre.

Underneath: row level security on every table, so hiding a menu item is never mistaken for stopping somebody reading the data behind it, plus error monitoring and alerting so a breakage reaches us before it reaches you. The full list of what we have built and where it runs is in the capability catalogue.

Apps start at £8,000+ and go up with what is in them: accounts, payments, messaging, video, offline behaviour and a second platform all add real work. The estimator prices your actual scope and emails you a range and a timeline, without a call.

Sometimes the answer is not to build one. If your users would be equally well served by a website they can add to their home screen, an app is a store listing, a review queue and an update cycle you did not need. We would rather tell you that at the start than take the money and let you find out.
