Custom Software

Progressive Web App Development Company in the USA

We are a US-based custom-software team in the Greater Seattle area building fast, installable progressive web apps that load instantly, work offline, and run on any phone or desktop. For service businesses and SaaS founders who want app reach without app-store friction.

01 · What You Get

What we build into every PWA

Every progressive web app we ship is engineered for speed, offline reliability, and an install experience that earns a spot on the home screen. Here is what that includes.

Installable on any device

Your app installs straight from the browser to the home screen on Android, iOS, Windows, and Mac, with a proper icon, splash screen, and full-screen launch, no app store and no download wait.

Works offline and on bad connections

We wire up service workers and smart caching so the core screens load instantly and keep working in dead zones, basements, and spotty job-site networks, then sync changes the moment a connection returns.

App-like speed and feel

Considered progressive web app design with native-style navigation, gestures, and transitions means the app responds the instant a user taps, not after a spinner. Fast first load, faster repeat visits.

Push notifications and re-engagement

Bring customers back with web push for order updates, appointment reminders, or new listings, the same re-engagement hook a native app gives you, without making anyone visit a store.

One codebase, found on Google

A single web codebase serves every platform and stays fully indexable, so the same app that lives on a phone's home screen also ranks in search and opens from a shared link.

Secure data and clean integrations

HTTPS by default, sensible authentication, and API connections to the tools you already run, from payments to your CRM, so the PWA fits your stack instead of fighting it.

02 · The Problem

A native app is expensive, slow to ship, and most people never install it

Building a separate iOS app and Android app means two codebases, two review queues, and two sets of update headaches. You wait days for Apple or Google to approve every change, you pay store fees, and you still have to convince busy customers to go find your app, download a hundred megabytes, and create an account before they ever see value. For most service businesses and early-stage SaaS, that funnel leaks badly long before anyone taps "install."

A plain website avoids that friction but gives up the things that make apps feel good: instant loading, a home-screen icon, push notifications, and a screen that still works when the train goes underground or the warehouse Wi-Fi drops. You end up choosing between reach and experience when you actually need both.

A progressive web app closes that gap. It is a real website that behaves like an installed app, indexed by Google and shareable with a single link, no store listing required. The hard part is doing it correctly so it is genuinely fast, reliably offline, and installable on every device, not a slow page with an icon bolted on.

03 · Proven Results

We have shipped a real web platform that earns its keep

For GottaRent we built a revenue-generating web app and portal from the ground up, the kind of always-on, multi-user platform that has to load fast, stay reliable, and work for people on the go. That is exactly the engineering discipline a serious progressive web app demands: thoughtful data flow, a clean installable experience, and an interface that holds up when real customers use it every day. We bring that same approach to PWAs, building software that performs in the field, not just in a demo.

04 · How We Work

How we build your progressive web app

/01

Scope and map the experience

We start with a free call to understand your users, the jobs they need to get done, and which screens must work offline. You leave with a clear feature map, a build plan, and a fixed quote.

/02

Design the interface

We turn the plan into a clickable design, applying progressive web app design patterns so navigation, install prompts, and offline states feel obvious and native long before any heavy code is written.

/03

Build, cache, and integrate

Our developers build the app on one modern codebase, set up service workers and caching for offline use, and connect the APIs, payments, and data sources your business depends on.

/04

Test across devices and launch

We test installability, offline behavior, push notifications, and speed on real iPhones, Android phones, and desktops, then launch. You get a link to share, not a store review to wait on.

/05

Support and iterate

Because it is the web, updates go live the moment we ship them, no resubmission. We monitor performance and keep improving the app as you learn what users actually use.

05 · FAQ

Frequently Asked Questions

A progressive web app is a website built to behave like an installed app. Users add it to their home screen, it works offline, and it can send push notifications, but there is no app store download or review. A native app is built separately for iOS and Android, must be installed from a store, and needs approval for every update. A PWA gives you most of the app experience from one codebase that also ranks on Google.

Working with a US-based team in the same time zone means real-time calls, clear communication, and accountability over the data your app handles. As a Greater Seattle progressive web app development company, we scope, design, and build in-house, so you talk to the people writing the code, not a layer of account managers over an offshore shop.

Yes. We use service workers to cache the app's core screens and data so it keeps working without a connection, on a subway, in a basement, or on a weak job-site network. When the device reconnects, changes made offline sync automatically. We decide together which features must work offline and engineer for those during the build.

Strong progressive web app design starts with speed and clarity: instant first load, native-style navigation and gestures, a clear install prompt, and honest offline states so users always know what is happening. It should feel like an app the moment someone taps, while staying a searchable, linkable website underneath. We design those patterns up front rather than retrofitting them.

Yes. iOS supports adding progressive web apps to the home screen from Safari, where they launch full-screen with their own icon, just like a native app. We test installability on real iPhones, Android phones, and desktops so the experience is consistent across every device your customers use.

PWAs fall under our custom-software work, which typically ranges from $10,000 to $50,000 and up depending on the features, integrations, and offline behavior you need. We give you a fixed quote after a free scoping call so you know the full cost before any code is written, with no app-store fees on top.
