Staymark: Schengen & UK SRT

Staymark counts your travel days against three residency rules at once — Schengen 90/180, the UK Statutory Residence Test and the US substantial presence test — from a single trip log.

ASK BEFORE YOU BOOK
Start typing a trip you're only considering. Before you save it, Staymark shows whether it fits every limit it touches, the exact day it would break one, and — for the Schengen area — the latest day you could stay if you arrive on that date.

HOW IT COUNTS
• Schengen 90/180 — a rolling 180-day window; entry and exit days both count, matching the European Commission's counting method. See days used, days left, and the date the next day frees up.
• UK Statutory Residence Test — midnights per tax year against your own sufficient-ties limit. Tick the ties that apply (family, accommodation, work, 90-day, country) and arriver or leaver status.
• US substantial presence — this year, plus a third of last year, plus a sixth of the year before, against the 183-day formula.
• Home base — set your tax-residence country to count nights away this year, planned trips included.

WHAT YOU GET
• One trip log, three rule engines, one screen.
• A 180-day grid showing every counted and planned day at a glance.
• Quick entry: tap a recent country, tap "2 weeks", save.
• CSV import for years of history, and CSV export of every trip and every count — the file an accountant or adviser works from.
• No account, no location tracking, no permissions. Your trips stay on your phone and the app works offline.

WHO IT'S FOR
Frequent travellers, remote workers, digital nomads, contractors and anyone splitting time between the UK, the Schengen area and the US who needs to know, day by day, how close they are to a limit.

Staymark counts days and applies published statutory thresholds. It is not tax, legal or immigration advice — always confirm your position with a qualified professional.
