Also from Hall Dev Work · Apps & games
Hall Dev Work LLC is one developer — me, David Hall. Mostly I build websites for local businesses; this page is the other thing I do. I build cross-platform iOS and Android apps in React Native and Expo and take them through to App Store submission myself. Available for contract work and agency overflow.
What's in the works
Three apps, designed and built by one person — front end, backend, and everything in between. Here's where each one stands.
iOS app · Fitness training
A fitness training app. React Native and Expo on the front end, a Fastify API behind it, StoreKit subscriptions for billing, HealthKit for activity data, and EAS Build driving releases. Submitted to the App Store.
Designed, built, and submitted solo — front end, backend, subscriptions, and store submission.
Submitted to the App Store · awaiting releaseiOS game · Fight-gym management
A fight-gym management game — run the gym, train your fighters, and take them up the ladder. Built on the same React Native and Expo toolchain, with beta builds going out through TestFlight.
Designed, built, and shipped to testers solo — game design, simulation, and release pipeline.
In beta testing on TestFlight · launching 2027Boxing training app
A boxing training companion — round timer, combo caller, and guided workout rounds, with on-device pose detection driving live form feedback. Forked from the same React Native and Expo codebase into a standalone app.
Built solo — same React Native and Expo toolchain, front end to release pipeline.
In developmentWhat I do
Cross-platform iOS and Android apps in React Native and Expo — from the first TestFlight build through store review. Subscriptions, native integrations, and release pipelines included.
A working proof of your idea in weeks, not months. Put the core experience on a real device before committing a production budget.
Web apps and dashboards that share a codebase and design system with the mobile product where that makes sense.
Engine work I still take on — it just isn't the headline.
End-to-end work in Unreal Engine 5 and Godot 4, from vertical slice through release.
Character controllers, hit detection, combo and juggle systems, enemy AI, camera and lock-on.
Editor tooling, asset pipelines, and build automation.
Contact
Websites for local businesses are my main work, so I take on a small number of custom app and web-app projects at a time. If you have one, start with a call. You talk to the person writing the code, because that's the only person there is. NDAs welcome.
