ServicesApp development

Any app you can picture.iPhone, iPad, Android and Apple Watch.

We design, build and ship native and cross-platform apps, from a one-screen utility to a full platform with a web admin, a backend and AI. Every screen on this page comes from an app we built.

How simple, how complex

Small idea or big platform.We build pretty much anything.

Five kinds of app, from simple to complex. Most projects start at one level and grow into the next.

  1. Simple utility

    One job, done well.

    • A focused tool, tracker or calculator
    • Works offline
    • Settings and dark mode
    • Ready for the App Store
  2. Connected app

    Accounts, sync and alerts.

    • Sign in with Apple, Google or email
    • Data that syncs across devices
    • Push notifications
    • In-app purchases and subscriptions
  3. Business app

    Built for teams in the field.

    • Offline-first with sync
    • Roles and permissions
    • Camera and document scanning
    • Maps, routes and integrations

    Like SignMaster

  4. Platform

    Every screen your business runs on.

    • Apps for phone and tablet
    • A web app and admin
    • One backend behind all of it
    • Payments, accounting and AI

    Like LightMaster

  5. Anything else

    Watch, widgets, games and more.

    • Apple Watch apps and widgets
    • Games
    • AI features
    • Bluetooth, hardware and AR

Our own apps

Designed, builtand shipped by us.

Switch between three of our products. Every screen is a real capture from the app.

What we can build

Every part of a great app.

Pick the pieces your idea needs. Many of them already run in our own products.

Swift · SwiftUI

Native iOS

Apps that feel at home on iPhone and iPad, built with Apple's own tools for the smoothest scrolling and the newest features.

Kotlin · Jetpack Compose

Android

Native Android apps that follow Google's design rules and run well across the wide range of Android phones.

React Native · Expo

Cross-platform

One codebase for iPhone and Android, when reaching both quickly matters more than platform-specific polish.

watchOS · WidgetKit

Apple Watch and widgets

Timers, stats and quick actions on the wrist and the Home Screen, so people get what they need without opening the app.

Sync

Offline-first sync

Work keeps going in a basement or a dead zone. Changes save on the device and sync when the signal comes back.

Camera

Camera, scanning and documents

Scan paperwork, snap job photos, read barcodes and turn pages into clean PDFs ready to sign or send.

Maps

Maps and routing

Jobs on a map, a sensible order to visit them, and a one-tap handoff to Apple Maps or Google Maps.

Stripe · In-app purchase

Payments and subscriptions

Take card payments, sell subscriptions through the App Store and Google Play, or send invoices through Stripe.

Notifications

Push and notifications

Reminders, status updates and alerts that bring people back at the right moment, with settings they control.

OpenAI · Claude

AI features

Assistants that fill forms, summarize, answer questions or create images, with guardrails you decide.

Games

Games

Casual and arcade games with tight touch controls, sound and progression, like our archery game Arcane Power Shot.

Launch

App Store and Google Play

We prepare the listings, screenshots and review notes, handle submission, and ship every update after launch.

LightMaster

One backend.
Every screen.

LightMaster is an all-in-one CRM for holiday lighting pros. We built the web app, the iPhone and iPad apps, and the backend they share.

  • LumenAI mockups

    Photo-real AI lighting on a photo of the customer's own house, so they see the job before they buy.

  • Estimates and proposals

    Measurements, designs and pricing come together in one proposal.

  • Scheduling and routes

    Install days, crews and the drive between jobs, planned in one place.

  • Payments and accounting

    Connected to Stripe, QuickBooks Online and HighLevel.

And the rest

Beyond the phone.Watch, widgets, games and AI.

If your idea needs it, we can build it. Here's some of the less ordinary work from our own products.

Games.

Arcane Power Shot is a one-finger fantasy archery game for iPhone, now on the App Store.

Apple Watch and widgets.

Solmate pairs its native iPhone app with Home Screen widgets and an Apple Watch app.

The process

From idea to App Store.

  1. 01

    Idea

    We talk through who it's for and what it must do, then send a written plan and quote.

  2. 02

    Design

    You tap through a clickable prototype and approve the screens before we write code.

  3. 03

    Build

    We build in short cycles, and new TestFlight builds land on your phone as we go.

  4. 04

    Launch

    We prepare the listing, submit for App Store review, answer Apple's questions and release.

  5. 05

    Update

    Fixes, improvements and new features after launch, each shipped through review.

Questions? Answers.

iPhone, Android or both?

Start where your customers are. Many business apps launch on iPhone first and add Android next. If you need both on day one, we can build them together from one codebase.

Native or cross-platform?

Native (Swift for iPhone, Kotlin for Android) gives the most polish and the newest platform features first. Cross-platform (React Native with Expo) shares one codebase across both. Your written plan recommends one and explains why.

How long does an app take?

It depends on the scope. A focused utility is a much shorter project than a platform with a web admin and a backend. Your plan breaks the work into milestones with dates, and you'll have TestFlight builds on your phone along the way.

Do you handle App Store review?

Yes. We prepare the listing, privacy details and review notes, submit the build and respond if Apple has questions. We plan launch dates with time for review built in.

Who owns the app and the developer accounts?

We recommend publishing under your own Apple Developer and Google Play accounts, so the listing, reviews and customers stay with your business. We'll help you set them up.

What happens after launch?

We keep going. We fix issues, add features and keep the app current with new iOS and Android releases. LightMaster Mobile has shipped six updates since its September 21 launch.

Can you build the web admin and backend too?

Yes. Most business apps need one. We build the web dashboard and the backend (database, sign-in, storage and APIs) alongside the app, the same way we did for LightMaster.
