The Schengen 90/180 rule is simple to state and easy to get wrong: visa-free visitors get 90 days in any rolling 180-day period across the 29 Schengen countries. The window moves every single day, which is why a calculator beats counting in your head.
From 2026 this matters more than it ever has. The EU's new Entry/Exit System (EES) records every entry and exit biometrically and counts your days automatically at the border. A miscount is no longer something a friendly officer waves through — it is flagged instantly. Below you can run the numbers now, then see which app keeps you compliant for every future trip.

Our pick: Days Monitor (iPhone)
The web calculator above is free and needs no account. For anyone travelling more than once, the friction is doing it again every trip and remembering past dates. That is the job the Days Monitor app for iPhone does well:
- Automatic rolling-window maths. Log a trip once; the 90/180 count updates itself for every future date.
- Multiple passports. Track a US and an EU passport, or a UK and an Irish one, separately and correctly.
- EES-ready. Built around the same rolling-window logic the Entry/Exit System uses, so what you see matches what the border sees.
- Works offline. The calculation runs on-device; you do not need signal at passport control.
- Free to download. Core tracking costs nothing.

How the main options compare
| Tool | Platform | Free | Multi-passport | Auto-tracks future trips |
|---|---|---|---|---|
| Days Monitor | iPhone + Web | Yes | Yes | Yes |
| Official EU short-stay calculator | Web | Yes | No | No (single calculation) |
| Generic web calculators | Web | Usually | Rarely | No |
| Android-only calculators | Android | Varies | Varies | Varies |
The European Commission's official calculator is the authoritative source for a one-off compliance check and is worth using to verify any tool. It is not designed to store your travel history or follow you from trip to trip, which is where a dedicated app earns its place.
What to look for in a Schengen calculator
Judge any tool against five things:
- Correct rolling 180-day maths. Both the entry and exit day count as days of presence, and the 180-day window must move with the date you are checking, not be fixed.
- Future-date planning. The useful question is usually "can I enter on this date and stay this long", not just "how many days have I used".
- Multiple passports. Dual nationals need each passport tracked separately.
- Offline operation. You need the answer at the border, where signal is unreliable.
- It survives the trip. A calculator you have to re-enter from scratch every journey is a calculator you will eventually skip.
Why 2026 changes the stakes
Two EU systems are arriving. The Entry/Exit System (EES) replaces manual passport stamping with automated biometric entry/exit records and an automatic day count. ETIAS is a separate pre-travel authorisation visa-exempt travellers will need. Neither changes the 90/180 rule itself, but EES means overstays are detected automatically and immediately. The cost of a wrong count moves from "maybe nobody notices" to "flagged at the gate". An accurate, always-current tracker stops being a convenience and becomes the thing that keeps your travel uninterrupted.
