Stay Vault: Visa Day Counter
Schengen 90/180 & Tax Days
Free · Designed for iPad. Not verified for macOS.
Overstay a Schengen visa or trigger UK/US tax residency by accident? Track every day privately on your device — no account, no cloud
Stay Vault Days counts your days in every country and checks them against the rules that actually matter — Schengen 90/180, the UK Statutory Residence Test,
the US Substantial Presence Test, UAE tax residency and more — so you always know where you stand before you cross a line.
It's the private day counter for digital nomads, expats and anyone who can't afford to miscount: one overstayed border or one accidental tax residency can cost you a ban or a tax bill. Stay Vault Days does the maths automatically, in the background, and warns you before it's a problem.
QUESTIONS STAY VAULT DAYS ANSWERS
• How many days can I stay in the Schengen area? Track the 90-days-in-any-180 rolling window and see exactly how many you have left today — or on any future date.
• Am I a UK tax resident? Run the Statutory Residence Test (SRT): the automatic tests plus the sufficient-ties test, where residence can trigger in as few as 16 days.
• Is the 183-day rule real? See why "183 days" is often a myth and your true tax-residence limit can be far lower.
• What is the US Substantial Presence Test? Track this year's days and the 1/3 + 1/6 weighting carried over from the previous two years.
• Will my next trip push me over a limit? Plan a hypothetical trip and watch its impact across every counter before you book it.
• Did I become resident in two countries at once? Dual-residence conflict alerts flag the trap — for example, a UK leaver in Dubai balancing SRT ties against treaty tax-certificate days.
WHO IT'S FOR
• Digital nomads living on the Schengen 90/180 clock
• People leaving the UK for Dubai, Portugal, Spain or anywhere with a tax angle
