Track your days. Defend your residency.
We never receive your data. MIN184 has no accounts, no servers, no analytics, no ads, and no third-party code. Everything it records lives on your iPhone and — only if you keep iCloud sync on — in your own private iCloud, which nobody else can read, including us.
Most states tax you as a resident if you don't spend the majority of the year (184 days) at your primary home. MIN184 keeps the score automatically.
Quiet GPS samples, photo locations, calendar events, and workout routes build a contemporaneous record — the kind auditors respect.
Per-state day counts show what each state could claim, and the domicile checklist tracks the ties that decide close cases.
One tap exports CSV, PDF, or a complete Audit Defense Pack with methodology notes — bring it straight to your CPA.
MIN184 produces evidence, not legal conclusions. It is not tax advice.
