Mobile app development studio
We design and build iPhone, iPad, Mac, and Android apps that ship.
Small team, deep bench. Since 1998 we've created solutions for our customers; over the past five years we've shipped mobile apps and cloud services for paying client engagements — most under NDA. Our latest product on the App Store, direct from R.L.SAND, is R.L.SAND HOME.
Native iOS
Swift, SwiftUI, HomeKit, AVFoundation, Core ML. Apps that feel like Apple built them.
React Native
One codebase, two stores. TypeScript, Expo, native modules where the platform demands it.
AI integration
LLMs, on-device inference, structured tool use. We've shipped real AI features, not demos.
Cloud backends
Web services on Google Cloud, AWS, and Azure. APIs, auth, databases, real-time.
What the apps deliver
AI that earns its keep. Apps that talk to your data.
AI
AI that earns its keep
Real AI features inside your app — summarizing, classifying, extracting, drafting — built for the specific job your users have, with the latency, cost, and failure modes engineered for production. Not a chatbot tab tacked on the side.
Data
Connected to your systems
Custom mobile apps backed by web services we build alongside them. They pull live from your databases, internal APIs, and SaaS tools so field staff and customers see the same data your ops dashboards do — filtered, scoped, secured, and synced in real time.

How we work
Three things you can count on.
01
Direct access to engineers
The engineer on your kickoff call is the one writing the code. You talk directly with the people building your app.
02
AI for speed, review for quality
We use AI tooling to move faster. Code is tested and reviewed before it ships — App Store-ready, not "ships and we'll see."
03
Ship early, iterate from real use
We aim for a useful first version in users' hands, then improve based on what people actually do with it.
