Staying in Europe
The simplest Schengen calculator for British citizens
The Problem
Post-Brexit, British citizens can only spend 90 days in the Schengen zone within any 180-day rolling window. Sounds simple. It isn't.
Try calculating it yourself: "I spent 14 days in Spain in March, 8 days in France in May, and now it's August — how many days do I have left?" The rolling window makes this genuinely confusing.
Existing calculators were clunky, ugly, or demanded too much input. British expats and frequent travellers needed something simple that just works.
The Approach
1. Ruthless Simplicity
One purpose. No feature creep. Enter your trips, see your remaining days. That's it.
2. Mobile-First Design
You're checking this at the airport, in a café abroad, on your phone. It has to work perfectly there.
3. Visual Clarity
The 180-day window visualised so you can actually understand what's happening. Not just a number — a picture.
The Build
- React app — Fast, responsive, works offline
- Local storage — Your trips saved on your device
- Rolling window logic — The hard bit, handled for you
- Clean UI — Inter font, minimal design, zero friction
The Outcome
A tool that solves one problem completely. No account needed, no upsell, just utility.
