Who You Work with on Your App

Seattle product managers, startup founders and operations directors usually reach us with a launch window and a small technical bench. We make working with us direct and easy to follow.

A Single Accountable Lead

Your named project lead owns delivery and answers your calls. Mobile engineers, designers and testers back them up, so the whole app is covered without extra hires on your side.

Updates That Respect Your Time

We meet on video, or in person by arrangement, and we plan around Pacific time. Written notes follow each call and cover what was decided, what shifted and what we need next.

Plugged Into Your Process

We join your product owner, designers and in-house engineers on the boards and repositories they already use, and we cooperate with any other supplier involved. Handover documents are clear and complete.

Apps We Build for Seattle Industries

Seattle’s economy is anchored by technology, and it also runs on shipping, aerospace, life sciences, green industry and visitors. Each one needs a different kind of app.

Technology and Internet

How we help
Mobile versions of web platforms, onboarding flows and push messaging.
Plan for
Frequent releases and heavy analytics

Maritime Trade and Logistics

How we help
Cargo status, gate and yard check-in, and driver apps.
Plan for
Terminal software, carrier feeds and document handoffs

Aerospace and Manufacturing

How we help
Parts traceability, inspection checklists and supplier apps.
Plan for
Rugged devices and strict document control

Life Sciences and Global Health

How we help
Study participant apps, clinic scheduling and field data capture.
Plan for
Health data handling and consent screens

Green Economy

How we help
Energy monitoring, site inspections and sustainability reporting.
Plan for
Sensor feeds and apps used outdoors

Tourism, Cruise and Events

How we help
Itineraries, ticket wallets and wayfinding for visitors.
Plan for
Roaming users, many languages and seasonal peaks
Deciding which privacy laws and sector rules reach your app belongs to your legal and compliance people. We build so they can trace where data is kept and who it’s shared with.

iOS, Android or Both? A Plain-English Guide

No route suits everyone. Your audience, timeline and features decide, and here is how we compare the four.
Option

Native iOS

iOS app development
Pick it when
Most of your audience uses iPhones, or you want deep Apple features.
Watch for
You would need a separate Android build.
Option

Native Android

Android app development
Pick it when
Your users lean Android, or the app needs close device access.
Watch for
You would need a separate iPhone build.
Option

Cross-Platform

Flutter and React Native
Pick it when
One codebase ships to both stores, which helps when budget is tight.
Watch for
Unusual hardware may still call for native code.
Option

Web App or PWA

Web application development
Pick it when
Users won’t install an app, or you are still testing demand.
Watch for
Fewer device features, and nothing listed in a store.
Unsure? Many Seattle teams begin cross-platform and add native code for the few features that need it.

What We Check Before an App Goes to the Stores

Many first releases get held up in store review, so every submission goes through the checks below first.
Read the Current Guidelines

Each feature compared with Apple’s App Review Guidelines and Google Play policies
Permission requests and privacy notes written in plain words
Stability and speed tests on a range of real handsets

What Shapes the Cost of an App

We keep prices off the page because apps range from a basic booking tool to a marketplace running on live data. Six things account for most of the variation.

Platforms

↑ Costs more when
iOS and Android each get their own native build
↓ Costs less when
a single cross-platform build serves both stores

Features

↑ Costs more when
payments, chat, maps and offline mode all arrive together
↓ Costs less when
release one follows a single core task

Design

↑ Costs more when
bespoke animation and a full design system are requested
↓ Costs less when
common interface patterns fit your brand

Integrations

↑ Costs more when
the app must connect to older operations or finance systems
↓ Costs less when
the services it calls are well documented

Back End

↑ Costs more when
live data, dashboards and admin tools need building
↓ Costs less when
a back end already in place can serve the app

Compliance

↑ Costs more when
health or payment data is held and audits follow
↓ Costs less when
the data it holds is low risk

Hire Mobile App Developers

Choose by stage. A founder with a defined first release often suits a fixed build, a business digitizing a manual process may like time and material, and a product team needing capacity suits dedicated developers.

Fixed Price Build

Everything is priced and scheduled before the first sprint. Fits a clear brief with a firm deadline.
Suits

Time and Material

Billing follows hours worked, and you reprioritize each sprint. Fits apps that shift as user feedback arrives.
Suits

Dedicated Developers

A mobile team of engineers, testers and a designer when required, working inside your sprints and tools. Fits a long roadmap.

How to Choose an App Development Company

Proposals tend to blur together. These seven questions show how a team acts once the work is under way.
01

Who Exactly Is Building My App?

Listen for
Real names and job titles for the people on your project.
02

When Can I Run a Working Version?

Listen for
Something you can install on your own phone after each sprint.
03

Whose Name Is on the Source Code and the Developer Accounts?

Listen for
Yours, written into the contract without fine print.
04

Can You Pick Up Where a Previous Supplier Stopped?

Listen for
A review of code and designs first, then a written recovery plan.
05

Who Looks After the App After Release?

Listen for
Post-release monitoring and fixes, with an update plan settled before launch day.
06

How Will You Cooperate with Our Own Engineers?

Listen for
Work tracked on your boards, with stand-ups and code reviews inside your own tools.
07

Will You Admit When a Web App Would Do the Job?

Listen for
A straight yes, after an honest comparison with a web app or an off-the-shelf tool.

How We Run an App Project

There are six stages, and each leaves you with something to review. Length varies with app size.
01

Discovery

About a week of workshops with your team, covering users, goals and constraints.
02

Scoping and UX

Typically one to two weeks, ending in an agreed scope, mapped user flows and a quote in writing.
03

Design and Prototype

Around two weeks of design work, finished with a prototype your test users can tap through.
04

Sprint Builds

Work moves in short sprints, and each one closes with an installable build to try.
05

Testing and Store Readiness

Around four weeks of checks on devices, performance and store requirements.
06

Launch and Iterate

We release, watch how the app performs and plan the next versions with you.
Each stage ends with something you can review.

The Villas Mooloolaba

Hospitality / Boutique Vacation Rental
The Villas Mooloolaba does the hard part well – four unique two-bedroom villas around a shared pool on Queensland’s Sunshine Coast. The website wasn’t carrying its weight: competing against hotel chains and OTA listings meant direct booking had to feel just as easy, and guests couldn’t easily compare all four villas.

eCommerce / Fashion & Apparel
Kayme does the hard part well – designing dresses people genuinely want, with a loyal following built over time.
