Mobile app studio · Portland, Maine

We build apps that hold their berth.

Harborlight Labs designs, builds and launches iOS and Android apps for founders and product teams — from first wireframe to App Store submission and every release after.

Services

Everything an app needs, under one roof.

Take only the piece you need — a build, a redesign, a rescue — or hand us the whole project and we'll run it end to end.

Wireframes first — screens get drawn before they get built.
01

iOS development

Native iPhone and iPad apps, built for the devices your users actually carry. From the first screen to App Store submission, with architecture kept deliberately plain so it stays easy to change.

  • Swift
  • Native iOS
  • App Store
02

Android development

Kotlin builds that hold up across the wide range of phones and tablets out there — different screen sizes, different OS versions, one steady experience.

  • Kotlin
  • Android
  • Play Store
03

React Native builds

One codebase when it's the right call for your budget and timeline. Shared logic underneath, platform-correct feel on top — no compromise at either store.

  • React Native
  • One codebase
  • iOS + Android
04

UI/UX design

Flows, wireframes and interfaces that get tested before they get coded. We draw the whole voyage first, so nobody is surprised by the build.

  • Research
  • Wireframes
  • Prototypes
05

API & backend integration

Your app has to talk to something. We wire up APIs, accounts, payments, data and third-party services, then make sure they keep answering when traffic arrives.

  • API work
  • Authentication
  • Data
06

Launch & maintenance

Store submission, screenshots, review notes and the launch itself. Then the long watch: crash triage, OS updates, and the next round of features after version one.

  • App store launch
  • Ongoing maintenance
  • Releases

Process

Five steps from idea to App Store.

The route from idea to published app is marked out in advance. You always know which stretch of water you're in, and what comes next.

01 · Sounding

Discovery

We meet, ask a lot of questions and map what the app has to do, who it's for, and what already exists.

02 · Dredge

Design

UI and UX: flows, wireframes and a clickable prototype you can put in front of real users before anything is built.

03 · Build

Engineering

Development in short, visible passes. You get working builds to hold in your hand, not status reports.

04 · Pilot

Launch

App Store and Play Store submission — listings, screenshots, review notes — and the launch itself, run to schedule.

05 · Deep water

Maintenance

Monitoring, updates and the next round of features once real users start telling you what they need.

Studio

Based in Portland. Built for the long term.

Harborlight Labs works out of Portland, Maine, on Casco Bay. Whether you're a first-time founder or a product team with an app already in the water, the process starts the same way: understand the ground, then build on it.
