We develop custom iOS and Android applications using Kotlin, Swift, Objective-C and Java. Our approach means that overall, the application delivered is yours, and is completely scalable and testable.
Built to last, not just to ship
A native app is easy to start and hard to keep. The difference shows up a year in, when the feature you need next either drops into place or forces a rewrite. We build for that second year: clear boundaries between layers, tests that describe real behaviour, and a codebase a new engineer can read without a guided tour.
That means writing in the platform’s own language and idioms — Kotlin and Java on Android, Swift and Objective-C on iOS — rather than fighting a cross-platform abstraction to reach the APIs you actually need.
Native or cross-platform?
Cross-platform frameworks like Flutter and React Native can be the right call: a content-driven app, a tight budget, or a first version built to test an idea. Native wins when the app leans on the platform itself — Bluetooth and connected hardware, background work, camera and sensors, accessibility, or performance your users will feel. It also wins when the app has to live for years through every OS release.
We will tell you honestly which one fits your product. And when the answer is native, you get an engineer who has been shipping on iOS and Android for well over a decade.
What we work on
- Custom iOS and Android applications, from first commit to store release
- Native development on iOS, Android, and Linux
- Integration with the web platforms and APIs that back the app
- Digitally integrated physical products, where the app is one part of a larger system
How we work
Test-driven development, continuous integration, and the practices of Extreme Programming are not add-ons here — they are how the work gets done. Every line is reviewed, tested, and owned by an experienced engineer.
We are based in St. Louis and work with clients across the United States, both on-site and remotely.
Selected work
- Mobile apps recognized by the White House as a Champion of Change
- A connected-home product ranked highest in customer satisfaction by J.D. Power
- Partnerships with Emerson and MLS club St. Louis CITY SC
- Engineering leadership for apps used by millions of people
The code is yours
You own the result. No proprietary framework to license, no dependency on us to keep it running. If you bring the work in-house or hand it to another team, the codebase, the tests, and the build pipeline go with it.
