Mobile Apps Built for How Portland Businesses Actually Operate
Modern mobile apps aren't add-ons to your business, they're often where the real work happens. Whether your team is tracking motion data in the field, managing fantasy leagues with thousands of concurrent users, or giving creators tools to collaborate on the move, the app has to perform under real conditions: unreliable connections, battery constraints, background syncing, and users who expect desktop-level functionality in their pocket.We're Portland app developers who build mobile applications that hold up to how businesses actually operate. Not just interfaces, complete systems designed for performance, reliability, and long-term growth.
Mobile App Development
Mobile development isn't just scaling down a website. It's building for interrupted connections on job sites, managing state across app backgrounds and restarts, handling sensors and hardware integrations, and ensuring every interaction feels immediate even when data is syncing behind the scenes. Portland businesses need mobile apps that function in the real world, on construction sites, in gyms during training sessions, at events with spotty wifi, or in hands moving between a dozen tabs and notifications. We approach mobile app development as product and system design: understanding where the app fits into workflows, what happens when things go offline, and how to structure data so the experience never feels like it's waiting on the network.We're not building prototypes that break under load. We're building production systems that Portland companies rely on daily.

Working With Portland Businesses and Beyond
We're based in Portland and work directly with local businesses who value in-person collaboration during discovery and key project phases. We understand the industries that drive the region, from tech and creative services to outdoor brands, healthcare, and field operations.
We also work remotely with companies outside Portland. Our process is built for clear communication regardless of location: structured updates, working builds you can test, and documentation that keeps everyone aligned.
Whether you're in Portland or beyond, you get the same attention to detail, technical rigor, and long-term thinking.
You Own Your App and Code
Ongoing Maintenance & OS Updates
Feature Expansion Without Rebuilds
Ownership, Support, and Growth
You own the app and the code we build for it. Once it launches, we can stay involved with ongoing maintenance, operating system updates, performance improvements, and new feature development as your needs change.
Because the product is built to grow, adding functionality should not mean starting over every time. Our goal is to give you a solid foundation you control, with a development team available when you need support, updates, or the next phase of the product.
Starting a Mobile App Project
Most projects start with a conversation, what problem you're solving, who's using the app, and what success looks like. From there, we scope out timeline, platform decisions, and budget.
Simple MVP apps often start in the $50,000–$80,000 range. More complex platforms with real-time data, hardware integrations, or extensive backend systems typically run $100,000–$250,000+. Every project is different, and we're transparent about what's realistic for your timeline and goals.
If you're ready to talk through a mobile app project, get in touch. We'll tell you what we think makes sense, and what doesn't.
Unique Solutions to Hard Problems
At SLIDEFACTORY, we know that every web project is unique, and building the right solution requires more than a template or theme. Based in Portland, Oregon, our team collaborates closely with clients to design and develop custom web solutions tailored to their goals.
Our Latest Works.
Our work blends technical expertise with creative problem-solving to deliver AI-powered solutions that solve complex challenges and produce measurable, lasting results for our clients in Portland, Oregon and beyond.
One codebase, both app stores
React Native is our default recommendation because it fits how most businesses actually need to ship: one codebase that runs on iOS and Android, native performance where users notice it, and a development budget that is not paying for everything twice. We go fully native when a project genuinely demands it, and we will show you the reasoning when it does.
The proof we point to is production longevity: apps we built years ago are still shipping updates, and our mobile development solution covers the stack decisions in detail.
From idea to the app stores without betting the company
The ladder matters more than the pitch. If the core idea is unproven, a proof-of-concept sprint starting at $7,500 tests the risky assumption in two to four weeks. When the idea holds, an MVP scoped to prove the business starts at $25,000, most landing between $25,000 and $60,000 over six to ten weeks.
Some PoCs end with a recommendation not to build. That is the process working, and it is the cheapest outcome we sell. We would rather lose a build than ship you an app nobody needed.

Do you build for iOS, Android, or both?
Both, usually from one React Native codebase, going fully native only when a project genuinely needs it. That keeps two app stores from costing you two development budgets.
What does a mobile app cost in Portland?
An MVP scoped to prove the business starts at $25,000, with most landing between $25,000 and $60,000. If you are earlier than that, a PoC sprint from $7,500 tests the risky part first. Scoping conversations cost nothing.
We do not have a technical team. Is that a problem?
No, most of our clients do not. We handle architecture, app store submission, and the decisions in between, and we explain them in plain language as we go. What we need from you is domain knowledge and decision speed, not a CTO.
Where are you located?
4520 SE Belmont St, Suite 300, in inner Southeast Portland, upstairs from the Horse Brass. Our clients run metro-wide, from Beaverton and Hillsboro to Gresham and Vancouver, and most of the work happens over short calls and shipped builds either way.
