Do you know how many days you've spent in each state this year? Your tax bill depends on it.
Tax Days tracks your days against the residency rules that matter, so you always know exactly where you stand. Track automatically in the background, or log trips by hand. Either way the app does the math across US states, the federal Substantial Presence Test, Schengen 90/180, the UK Statutory Residence Test, and more.
AUTOMATIC OR MANUAL, YOUR CHOICE
Turn on auto-tracking (Pro) and Tax Days detects trips in the background using battery-efficient location monitoring, then proposes them for you to confirm. Prefer to keep location off? Log trips by hand in seconds. Either way your location history stays on your iPhone. No accounts, no servers, nothing to hand over.
AUDIT-READY RECORDS
Export a per-jurisdiction PDF summary or a CSV trip log for any year, ready to hand to your accountant.…

Appworthy
tax-daysWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
