iOS App Development · Boston, MA

Native iOS apps, built the Apple way.

We design and engineer iOS apps in Swift and SwiftUI — the same stack we use for our own App Store products. No cross-platform compromises, no janky wrappers. Apps that feel like they came from Cupertino, built in Boston.

Capabilities

Everything an iOS launch takes

From first wireframe to App Store review and the version 2.0 that follows.

🧭

Product & UX design

Human Interface Guidelines-native design. Flows, prototypes, and pixel-final screens before a line of code.

⚙️

Swift & SwiftUI engineering

Modern, maintainable Swift with SwiftUI and async/await. Deep platform work — networking, hardware APIs, background tasks — when the app calls for it.

🔔

Platform integrations

Push notifications, Sign in with Apple, StoreKit subscriptions and in-app purchase, widgets, App Intents, and HealthKit.

🧪

Testing & CI

Unit and UI test suites, TestFlight beta programs, and automated build pipelines so every release is boring — in the good way.

🏪

App Store launch

Listing strategy, screenshots, review-guideline compliance, and submission. We've been through Apple review with our own apps.

🔁

Post-launch iteration

Analytics, crash monitoring, and a roadmap cadence that keeps your app improving after 1.0.

How we work

From idea to App Store in four moves

  1. 01

    Discover

    We dig into the problem, the users, and the business case. You leave with a scoped plan and honest estimate.

  2. 02

    Design

    Interactive prototypes you can hold on your phone before committing to a full build.

  3. 03

    Build

    Weekly TestFlight builds. You watch the app come together on your own device, not in slide decks.

  4. 04

    Launch & grow

    App Store submission, launch support, and iteration driven by real usage data.
