Which is the best Schengen calculator app? Mine of course! 

 

About 90 Days in Schengen Planner for Android and iOS

I live in France, so I don’t personally need to track the 90/180‑day rule — but many of my friends with second homes here do. After hearing how confusing the rule was, and after watching them struggle with tools that were inaccurate, full of ads, or locked behind subscriptions, I decided to build something better for them.

That’s how I ended up creating my own Schengen calculator — a simple, accurate way to plan stays in the Schengen area without stress, noise, or hidden costs.

What I wanted this app to be

    Accurate and trustworthy

The 90/180‑day rule is strict, and mistakes can cause real problems at the border. I built the app so you can adjust any trip and instantly see how it affects your remaining allowance. Everything follows the official rolling‑window method.

    Clear and intuitive

Second home owners tested early versions and pushed me to simplify things: tapping dates to change them, naming trips, switching between past and future with a swipe, and using a scrollable 180‑day calendar to make the rule easier to visualise.

    All your travel in one place (on Android, this feature update will be ready shortly for iOS)

Track your Schengen days and also mark trips outside the Schengen zone as non‑Schengen, so you can keep them in your timeline without affecting the day count.

    No ads, no subscriptions, no tracking

I don’t collect data, I don’t share anything with third parties, I don’t run ads and I don’t ask for a subscription. You pay once, and the app is yours.

    Stable and predictable

A lot of Schengen apps struggle with crashes, lost data, or incorrect calculations. I’ve put a lot of care into making sure the app behaves consistently and doesn’t surprise you.

Who I built this for

This app is for anyone who spends extended time in the Schengen area without living here full‑time — second‑home owners, digital nomads, frequent travellers and anyone who wants to maximize their time allowed in Europe. It’s designed to give you a clear, dependable view of your allowance without ads, subscriptions, or complicated dashboards.

Get the app
