App development · Stuart, FL
Custom mobile and web apps, from idea to App Store.
Have an idea for an app, or one that needs finishing? We design, build and launch mobile and web apps, all the way through App Store submission. Based in Stuart, FL, working with clients anywhere.
Work directly with the people who build your app
We're a two-person team: one of us turns your idea or business process into a clear plan, the other builds it. You talk to both of us from the first call to launch, with no account managers and no handoffs.
We've taken apps from zero to a working product, including an AI-powered home-diagnostics app we built ourselves and a client's yoga app that's moving through App Store submission.
Is this where you are?
- You have an app idea and don't know where to start
- You started an app and it's stalled or half-finished
- Your business runs on a spreadsheet that should be an app
- You need something your staff or customers can use on a phone
- You're not sure how App Store submission works
- You want to see a working prototype before committing
We can probably automate it.

HouseIQ: an AI app we designed and built end to end
HouseIQ is our own AI home-diagnostics app: describe a home problem and get an AI-assisted diagnosis with next steps. It's a working prototype that isn't live in the App Store, and the demo page is a web recreation using sample answers.

Frequently asked questions
Do you build both mobile apps and web apps?
Yes. We build mobile-first apps and web applications, and choose the approach that fits your idea and budget.
Can you finish an app someone else started?
Often, yes. Tell us where it stands in a free workflow review and we'll give you an honest assessment of what's salvageable.
Do you handle App Store submission?
Yes. We prepare and manage the submission package, including the listing, screenshots and privacy details. The approval itself is up to Apple or Google.
Can I see something before I commit?
Yes. We start by mapping your workflow and agreeing on a plan, and we're happy to show working demos of what we've built so you know what to expect.
