Custom Software
Mobile & Cross-Platform App Development in Seattle
Most mobile app development companies build for one platform at a time. We build cross-platform apps from a single codebase, so your product runs on the web, iPhone, and Android at once — custom software designed and shipped by a local Greater Seattle team.
What our web & mobile app development covers
We are a custom-software shop first, so a mobile app is rarely the whole job — it is usually one face of a system that also includes a web app, a portal, and an admin backend. Here is what a typical engagement includes.
Cross-platform web app development
We build one codebase that ships to the browser, iOS, and Android instead of maintaining three separate apps. Cross platform web app development means your features, fixes, and design stay in sync everywhere — and your budget goes to building, not to duplicating work three times.
Native-quality mobile UX
Cross-platform does not mean compromise. We tune navigation, gestures, offline behavior, and push notifications so the app feels right on a phone — not like a website crammed into an app shell.
Web app + admin backend
Behind almost every app is the part your team actually lives in: dashboards, user management, content tools, and reporting. We build the customer-facing app and the internal admin together so the whole product is coherent.
API integration & payments
We connect to the tools your business already runs on — Stripe and payment processing, CRMs, scheduling, mapping, email and SMS, and any third-party API your workflow depends on.
Accounts, auth & roles
Secure sign-in, password resets, social login, and role-based access so owners, staff, and customers each see exactly what they should — the foundation any real product needs.
Launch, App Store & support
We handle the App Store and Google Play submission process, set up monitoring, and stay on as your maintenance partner. Because the code is local and well-documented, you are never stuck waiting on a vanished offshore team.
A real multi-platform product, built and shipped
We built GottaRent, a property-management web app and tenant portal, as a true multi-platform product — landlords manage listings and applications from a desktop dashboard while renters browse and apply from their phones, all running on one shared codebase. It is a working example of the same approach we bring to mobile app development: one system, multiple devices, real accounts and payments, and software built to keep earning its keep rather than sit on a shelf.

Why most app projects stall before launch
If you have looked at hiring an agency, you have probably seen the same pattern: a quote for an iOS app, a separate quote for Android, and yet another conversation about a website. Three codebases, three timelines, three teams to coordinate — and the bill climbs fast before a single screen ships. For a small or mid-sized business, that is how a good idea dies in a planning deck.
The other trap is the offshore handoff. You get a low estimate, then spend months in time-zone limbo, re-explaining your business on every call, and end up with code nobody local can maintain. When something breaks, you are stuck. We have rebuilt more than one app that started this way.
What you actually want is one product that works everywhere your customers are, built by people you can sit down with in the same time zone. That is the whole point of how we approach mobile app development — fewer codebases, clearer ownership, and software you can grow into instead of throw away.
How we take an app from idea to live
Scope & fixed estimate
We start with a short working session to map who uses the app, what it has to do, and which platforms matter on day one. You leave with a clear scope and a written estimate — custom software projects with us typically run $10k–$50k+, and we tell you where yours lands before you commit.
Design & clickable prototype
Before we write production code, we put a clickable prototype in front of you so you can feel the flow on a real phone screen. This is where we settle navigation and the core experience, so there are no surprises later.
Build in working slices
We build the single cross-platform codebase in slices you can use, demoing real, working features every week or two. You watch the web and mobile versions come together side by side instead of waiting months for a big reveal.
Test, launch & hand over
We test across devices, ship to the web and submit to the app stores, and hand over clean, documented code. From there we either support it on a retainer or help your own team take the wheel.
