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.
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.
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.
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.

How we build your progressive web app
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.
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.
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.
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.
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.
