About

If you've ever spent a chunk of time in Europe without actually living there, you know the feeling:

I thought I had a decent grip on the 90/180 rule… until I didn't.

I was trying to plan another trip, and despite all the calculators online, I still couldn't see how my previous stays were affecting my current window. Everything felt like guesswork, and I kept finding myself manually counting days.

So I built something that would actually make sense to my brain.

Why build another calculator?

There are plenty of Schengen calculators out there. And they're fine… but they weren't doing it for me.

None of them gave me a proper visual timeline.

I wanted clarity and something that literally showed my trips, the rolling 180-day window, and which stay was about to “fall off.”

My timing really matters right now.

I'm preparing for residency in Luxembourg, which means I've been tiptoeing right up to the limit without realising it. A trip I took months ago was quietly blocking me from flying back sooner. Not ideal.

I learn best by building things.

I've been experimenting with AI development tools lately, especially Vercel's v0, and this felt like the perfect little project to test what's possible.

I just wanted a tool that made Schengen compliance feel less like a math exam and more like… a calendar.

Who this is actually useful for

After building it, I realised it's not just for me:

• Digital nomads bouncing between Lisbon, Berlin, Barcelona
• Retirees planning those long, dreamy motorcycle trips across Europe
• People in long-distance relationships trying to maximise time together without accidentally overstaying
• Remote workers who do month-long stints in Rome, not realising those days haunt them months later
• Anyone timing an EU residency application and needing to avoid missteps

Basically: anyone who wants a clear picture instead of a headache.

What it does

• Shows your stays on a clean, visual timeline
• Updates your remaining days instantly
• Shows which trip will fall out of your 180-day window next
• Helps you plan future travel without guessing
• Reduces that low-level “am I allowed back in?” anxiety

It's fast and honestly fun to play with. If you try it and have ideas, I'd love to hear them. This is one of those little projects born out of curiosity and mild panic, but if it helps anyone else avoid surprises at passport control, then amazing.
