ResiDays Alternative: Tax Days vs ResiDays Compared (2026)
ResiDays was released on October 19, 2026, and is aimed first at people in North America: it tracks countries, US states and Canadian provinces, follows Canada permanent-residence and citizenship progress, and can import US I-94 travel records from the CBP website. Its own listing is careful to say that day counts support planning and do not determine legal or tax residency. Tax Days is built for that second question: it applies the residency tests for 200+ jurisdictions, including all 50 US states and the federal Substantial Presence Test, for $29.99/year. (ResiDays facts below are from its App Store listing as of October 2026.)

Which one is right for you?
Tax Days is best for…
- Anyone who needs a residency test applied, not just a count of days.
- People who want days logged automatically instead of entered or imported.
- Taxpayers with exposure outside North America, including the UK and Schengen.
ResiDays is best for…
- Canadian permanent residents tracking PR and citizenship day requirements.
- Travellers who want to pull official I-94 records into their history.
- People who also want a travel map, globe and journey replays.
Bottom line: ResiDays is a promising new travel journal with two features Tax Days does not have: Canada PR and citizenship tracking, and I-94 import. It is explicit that its counts are for planning, not residency determinations. If your question is "am I a tax resident here?", Tax Days applies the actual tests, in the US, its states, the UK and beyond, and can log your days automatically.
