We Build Apps Experiences Products Tools
Native and cross-platform mobile apps for iOS and Android — from concept and design through App Store and Google Play launch. We also build our own apps, so we know what it takes to ship and grow a product.
Start a ProjectDevelopment & Our Apps
We build mobile apps for clients on both major platforms — and we put our own products in the same stores. Explore our development services or take a look at what we're building.
App Development
iOS App Development
Native Swift and SwiftUI apps built for iPhone and iPad. We handle architecture, App Store submission, and the polish Apple users expect — from first build to launch and beyond.
Android App Development
Native Kotlin and Jetpack Compose apps engineered for the full range of Android devices. Clean architecture, Google Play release management, and performance that holds up everywhere.
Our Apps
Clear Water
Our app for pool owners — log a water test, get a clear dose recommendation, and keep the water balanced. Available now on the App Store and Google Play.
Baby Nova
A free child-development milestone tracker based on CDC guidance. Available in 8 languages and built privacy-first, for iOS and Android.
Fast To-Do
Our to-do app — write it down fast, then organize it later with tags, nested lists, due dates, and reminders. Available now on the App Store and Google Play.
D2X Fitness Timer
Ten workout clocks in one timer — intervals, Tabata, AMRAP, EMOM, hangboard repeaters and more. Twelve languages, nothing on a server. Available now on the App Store and Google Play.
Lower Beast Side Trainer
A new kickboxing routine every session, built round by round, with a technique page for every strike. Available now on the App Store and Google Play.
D2X Macro Calculator & Meal Planner
A macro calculator that shows its work — every reference figure cited to the US federal publication it came from, 12,000+ USDA foods searchable offline, and the whole log kept on your own phone. Available now on the App Store and Google Play.
