We build, enhance, and maintain mobile apps

PocketBuilt is a boutique studio specializing in Swift/SwiftUI for iPhone, iPad, and Apple Watch. We ship new apps, rescue legacy codebases, and run ongoing maintenance so your product stays fast, stable, and delightful.

What we do

New App Builds

From zero to App Store: discovery, UX/UI, architecture, implementation, and launch. Native Swift/SwiftUI with scalable foundations.

  • iPhone, iPad, and Apple Watch
  • Offline-first and sync-ready architectures
  • Secure auth, subscriptions, and in-app purchases

Feature Revamps

Ship impactful improvements without derailing your roadmap—redesign flows, modernize UI, and add the features your users want.

  • SwiftUI redesigns that respect UIKit foundations
  • Accessibility, localization, and theming
  • Graphs, charts, and rich media experiences

Maintenance & Reliability

Keep your app healthy: updates, bug fixes, OS migrations, and performance tuning on a predictable cadence.

  • Swift concurrency, Combine, or RxSwift migrations
  • Crash reduction, memory, and startup optimizations
  • CI/CD hardening and test coverage improvements

Rescues & Refactors

Stuck with legacy code? We untangle Objective‑C, heavy view controllers, and complex BLE/Health integrations.

  • CoreBluetooth & HealthKit expertise
  • Database work: GRDB/SQLite, Core Data
  • Android delivered via trusted partners

Performance & Product Quality

We obsess over user experience and reliability—smooth animations, responsive interfaces, and robust networking. Expect clean architecture, clear documentation, and code your in‑house team can own.

FAQ

Frequent questions & answers

What kinds of projects do you take?

New mobile apps, feature revamps, maintenance retainers, and legacy rescues. iOS-first with watchOS and iPad support; Android available via partners.

What technologies do you use?

Swift, SwiftUI, UIKit, Combine, Swift Concurrency, Objective‑C when needed, GRDB/SQLite, CoreBluetooth, HealthKit, StoreKit, and modern CI/CD.

How do we work together?

We typically start with a discovery sprint to clarify scope and deliverables. From there we work in weekly iterations with TestFlight builds and regular check‑ins.

Can you help with an existing codebase?

Yes. We audit architecture, identify risk areas, and propose a staged plan to stabilize, modernize, and accelerate delivery.

Do you work with startups or enterprises?

Both. We tailor our engagement model to fit your team size, compliance needs, and release cadence.
