Question 1

How does the Schengen 90/180 rule actually work?

Accepted Answer

You may spend at most 90 days in the Schengen Area within any rolling 180-day period. The window is rolling, not annual: days leave it only by ageing past 180 days, so leaving the area and returning does not reset anything. Both your entry day and exit day count as full days, and the limit is tested on every day of your stay, not only at the border.

Question 2

Is this Schengen calculator free?

Accepted Answer

Yes. Logging trips and seeing your current Schengen status is free forever and needs no account. Paid features cover forward planning, threshold alerts, the year-end presence report and exports.

Question 3

Does it track tax residency as well as visa days?

Accepted Answer

Yes. It counts days per country against each country's own residency threshold, including countries whose tax year is not January to December. South Africa runs March to February, Mauritius July to June. It reports your recorded days against the published threshold; it never tells you that you are tax resident somewhere, because that depends on factors beyond day counting.

Question 4

Does it work without internet?

Accepted Answer

Yes. City data, your trips and your visa requirements are cached on the device, and the day-counting engine runs locally. It is designed to work in an immigration queue with no roaming.
