About this app

Daysium — the evidence platform for tax residency, built for globally mobile lives.

Daysium elegantly resolves the risks and complexities of day counting and record-keeping for globally mobile individuals, their families and their advisors.

What Daysium does:
- Automatic Location Logging — Your phone's GPS logs your location in the background, so your record builds itself as you travel.
- Photographic Evidence — Add geo-tagged photos to strengthen your record with visual evidence of where you were.
- Coded Tax Rules, Every Jurisdiction — See your live day count and status against each country's actual coded tax residency rules, wherever your travel takes you.
- Forward Planning — Model upcoming trips against the tax rules before you book, so you can see the impact on your day counts in advance.
- One Record, Not a Spreadsheet — Stop reconciling manual logs. Daysium replaces the spreadsheet with a single, reliable system of record.

One miscounted day can carry real financial consequences. Daysium gives you the precision to count accurately and the record to demonstrate reasonable care — without the manual effort.

Daysium brings rule establishment, planning, day counting and evidencing together in one place — built for the complexity of modern, globally mobile lives.
