Tristar Dynamics is a solo iOS studio building mobile tools for two of America's largest uniformed workforces — the U.S. military and the U.S. Postal Service.
Personal finance built around the realities of military pay — base pay, allowances, deployment entitlements, and TSP — for active duty, Reserve, Guard, and veterans.
A craft-aware utility for the USPS workday — schedule tracking, pay calculation, and tools tuned to City Letter Carriers, Clerks, Mail Handlers, and Rural Carriers.
Every Tristar Dynamics app starts the same way: I see people stuck with software that wasn't built for the way their job actually works. So I built the tools that should have already existed — convenient, fast, and shaped around the workday.
Every app runs on-device. No third-party SDKs. No analytics pipes. No data leaving the phone unless the user explicitly sends it.
A private and a clerk should be able to afford the app on payday. Pricing is set against the audience, not against what the App Store will tolerate.
Every feature ships because someone in the field needs it, not because it polls well. If it doesn't survive contact with the actual job, it doesn't ship.
