Which Washington laws change how your app is built?
The Washington rules we design consent screens, data retention and breach logging around. A planning summary, not legal advice.
| Rule | What it means for the build |
|---|---|
| Consumer privacy law | No comprehensive consumer privacy law in force as of 2026-10-31. Apps serving users in other states still need to meet those states' rules, and sector laws (health, finance, children) apply regardless. |
| Data breach notification | RCW 19.255.010: notice deadline 30 calendar days after discovery (AG within 30 days if >500 residents). We build audit logs that show what data was touched, so notice can be accurate and on time. |
| My Health My Data Act, RCW 19.373 | Any entity handling consumer health data, no threshold: separate consent to collect and share, written authorization to sell, health data privacy policy, geofencing ban; private right of action. (effective 2024-03-31 (small businesses 2024-06-30)) |
| Biometric identifiers law, RCW 19.375 | Notice and consent (or opt-out mechanism) before enrolling biometrics for commercial purposes; limits on sale/disclosure; AG enforcement. (effective 2017-07-23) |
| Sales tax on SaaS | taxable: SaaS taxable as a digital automated service; since ESSB 5814 (2025-10-01) custom software, customization, website development and IT services are also retail sales.. Relevant if you will sell your app as a subscription. |
| Time zone | Pacific. Our team works from San Francisco (Pacific), with remote specialists covering other hours, so Seattle working hours overlap with ours every weekday. |
Checked 2026-10-31 against state sources; confirm with counsel before launch.
Apps and software we build for Seattle businesses
| Industry | The problem | What we build |
|---|---|---|
| Seed-stage startups | You have a raise to close and a product that exists only in slides. | A working MVP with sign-up, the core feature and billing, live in about 7 weeks so investors and pilot customers can use it. MVP development |
| Fitness and wellness apps | Users drop off after two weeks, and you are unsure what health data you can legally keep. | A social tracking app with group streaks and consent built to Washington's health-data rules, designed to keep people coming back. Mobile app development |
| Maritime and freight operators | Dispatch happens by phone and customers call all day to ask where their job is. | A crew app that works offline on the water plus a tracking portal for customers, so calls drop and jobs move faster. Mobile app development |
| B2B and professional services firms | Deals, documents and approvals are spread across email and three spreadsheets. | A custom pipeline and approval tool where every deal has one record and one owner. Custom CRM development |

What our AI and mobile app development company builds for Seattle teams
The Seattle founders who call us usually have a product idea and no spare engineers: a fitness or wellness app, a first MVP to show investors, or a mobile app beside an existing web product. We scope it in a week and ship a working version in about seven. Stridely holds 52% retention at ninety days against roughly 8% for solo trackers, and because health-adjacent apps here fall under the My Health My Data Act, we build the consent flow into version one.
Run a vessel, shipyard or freight business? Your pain is dispatch by phone and status updates nobody can see. We build mobile apps for crews that save work offline and sync at the dock, plus customer portals so clients stop calling for updates. Our Respond Central dispatch app cut request-to-crew time from 22 minutes to 3. Want AI on top, such as summaries of job notes or an assistant that answers customer status questions? See our AI app development work, then book the free call.

How to hire an app developer in Seattle: 5 things to settle first
- Does your app touch health data?
If your app tracks anything that could reveal a health condition, Washington's My Health My Data Act applies with no size threshold. Designing consent in from the start costs less than adding it later.
- Which part does your own team keep?
Many Seattle companies keep the core product in-house and hand us a defined piece: a mobile app, an internal tool, an AI feature. Agree the boundary and the handover in writing.
- Will crews lose signal?
Apps used on ferries, docks or in the Cascades should save work offline and sync later. Say so at scoping and we design for it from the start.
- Whose name are the code and accounts in?
With us, the repository, app store accounts and hosting are yours, and handover includes a recorded video walkthrough and written documentation.
- Is the scope and price in writing?
Screens, integrations, milestones and price on paper before any work. See our pricing page for what moves a build from $7,000 toward $30,000.

How much does it cost to build an app in Seattle?
With us, a typical mobile or web app costs $7,000 to around $25,000 to $30,000. A first version with a few core screens sits near the low end; payments, multiple user types and integrations move it higher. Location does not change our price, and you get a written quote after a free 30-minute call.
How fast can you build and launch an app?
Across our 44 published builds, the first release shipped in 5 to 10 weeks and the median was 7. Stridely took 6 weeks; Spirit Airlines' group booking platform took 10 because it runs on live fare inventory. You see a working demo every week, so there are no surprises at launch.
Are you an AI software development company in Seattle?
We build AI software for Seattle companies, working remotely from San Francisco on the same Pacific hours. That covers assistants and search on your own documents, AI features added to an existing app, and agents that handle routine work. Think K-12's Ingio is one example we built in 7 weeks. Pricing follows our usual $7,000 to around $25,000 to $30,000 range, quoted in writing.
How much does it cost to build an Android app?
An Android app from us usually costs $7,000 to around $25,000 to $30,000, depending on screens, user types, payments and integrations. If you also want an iPhone version, the written quote shows what the second platform adds. Google Play charges a one-time $25 registration fee, and we set up that account in your name so the listing stays yours.
Can you build a health or fitness app that complies with My Health My Data?
Yes. Washington's My Health My Data Act covers any business handling consumer health data, regardless of size, and lets consumers sue. We build separate consent for collecting and sharing, a health-data privacy policy, deletion on request and no geofencing around health facilities. Our StackStack and Stridely apps are examples of the category.
Do you build software for maritime and logistics companies in Seattle?
Yes. For maritime and freight firms we usually build crew apps that keep working offline, dispatch boards for the office and customer portals that show job status. Our Respond Central dispatch app for Life Line Ambulances cut the time from request to confirmed crew from 22 minutes to 3, the same pattern a freight dispatcher needs.
Are there app developers near me in Seattle, or do you work remotely?
We work remotely from San Francisco and do not have a Seattle office. Since we share Pacific time, every call and weekly demo happens in your normal working hours. Scoping, design reviews and handover all run over video, and the scope and quote are signed off in writing before work starts.
What should I ask an app developer before hiring?
Ask five things: who exactly writes the code, what similar apps they shipped with named clients, the price and milestones in writing, whose name the repository and store accounts will be in, and what handover and support look like. We answer all five before you sign, and our builds, timelines and price range are published on our site.
Should a Seattle startup hire engineers or use an app development company?
If you need a first release in weeks, an outside team is usually faster than recruiting, because version one often needs design, mobile, backend and QA at once. A common route is to let us ship version one, then hire a small team that takes over the code we hand you, with our recorded walkthrough and written documentation.
How do I choose an app development company in Seattle?
Judge on evidence. Ask for published builds with named clients and real results, the people who will write the code, a written scope with milestones and price, and confirmation that you will own the code and accounts. Then compare timelines. Any team that cannot show this is asking you to trust a pitch.
Who owns the code after you build my app?
You own it. The repository, app store listings and hosting accounts are created in your name. At handover we give you a recorded video walkthrough and written documentation so your next hire can take over. Ongoing support is optional and billed per hour.
