One codebase. iPhone, Android, and the web.
We build apps that run on iOS, Android, and the browser from a single codebase, so you ship to everyone at once instead of paying for three teams. You get a real product in the stores, not a prototype that dies on a laptop.
App development
Write once, run everywhere
We build on React Native and Expo, so the same code powers your iPhone app, your Android app, and the web. One team, one roadmap, one bug fix that lands everywhere. You move faster and your app stays consistent across every device.
Works without signal
Your app keeps working in a tunnel, on a job site, or on a plane. We store data on the device and sync it the moment a connection comes back. Nobody loses work because the wifi dropped, and nobody stares at a spinner.
Push notifications that land
We wire up push so you can reach people on the home screen, not just in an inbox they ignore. Order updates, reminders, a nudge to come back. Set up properly for both Apple and Android, with the permission flow done right so people actually say yes.
Native where it counts
Camera, GPS, biometric login, payments, the share sheet, deep links that open the right screen. We use the real device features so the app feels native, because to your users it is. No clunky webview wrapper pretending to be an app.
Shipped to the stores, by us
App Store and Play Store review is its own job, full of rejection reasons nobody warns you about. We handle the signing, the listing, the screenshots, the review notes, and the resubmits. You get a live download link, not a folder of build files.
Built to update fast
After launch, the real work starts. We set up over-the-air updates so we can push fixes and small changes without waiting days for store review. Crash reporting and analytics are in from day one, so we see problems before your users tell you.
How we work
From the first call to live, in weeks.
Scope
We sit down and figure out what the app actually needs to do in version one, and what can wait. You leave with clear screens, a real plan, and a build you can picture. We cut the nice-to-haves that would sink your timeline.
Build
We build in short cycles and put a working app on your phone early, so you tap through it instead of reading documents. You see progress every week, give feedback on the real thing, and we adjust before anything is set in stone.
Ship
We submit to both stores, get through review, and go live. We set up updates, monitoring, and crash alerts so the app keeps running smoothly. Then we stay on for the fixes and the next round of features.
Where this fits
Frequently asked
Do I need separate apps for iPhone and Android?
No. We build both from one codebase, so a feature or a fix happens once and lands on every device. That is half the cost and far less to maintain than two separate native teams building the same thing twice.
Can the app work offline?
Yes. We store data on the device and sync it back the moment a connection returns. People can keep working with no signal, which matters a lot for field teams, travel, and anywhere the wifi is unreliable.
Will you get it into the App Store and Play Store?
Yes, that is part of the job. We handle signing, store listings, screenshots, the review process, and any rejections that come up. You end up with a live, downloadable app, not a build sitting on a server.
What happens after launch?
We set up over-the-air updates, crash reporting, and analytics so we can push fixes fast and catch issues early. Most clients keep us on for ongoing changes and new features as the app grows.
