About this service
Native iOS apps written in Swift and SwiftUI, for products where performance, offline use or deep device features matter. We agree a tight first version, build it in short cycles you can test on your own phone through TestFlight, and handle App Store submission, including the review questions that delay most first launches.
The first version is always too big
Most app projects start with a feature list that would take a year to build. Months pass, budgets stretch and the app launches late with features nobody uses. Meanwhile, the one thing users needed most did not get enough attention.
We cut the first version down to what users need at launch, and write the rest onto a second list. Each build goes to your phone through TestFlight every week or two, so you see progress and can change direction early, when it is cheap.
App Store review is part of the project
First-time apps are often rejected, and the reasons are usually predictable: missing privacy explanations, a login wall without a demo account for reviewers, in-app purchases handled outside Apple's system, or an app that does too little to justify being an app.
We plan for review from the start. Privacy labels are filled in based on what the app actually collects, reviewers get test credentials and clear notes, and purchases follow Apple's rules. If a rejection still happens, we handle the reply and resubmission.
Ownership matters too. The developer account, certificates and code all belong to your company. If you change developers later, the app moves with you, not with us.

Questions
Native or cross-platform?
Native Swift suits apps that lean on iPhone features or need top performance. If you need Android too on a tight budget, the cross-platform app service may be the better fit.
What if Apple rejects the app?
We read the rejection, fix the issue or answer the reviewer, and resubmit. Most rejections are about metadata, privacy or login details and are solved within days.
Do you build the backend?
We connect to an existing API. A new backend is scoped separately, often as part of a full-stack web app.
