Show HN: Schengen Calculator – Avoid €5K Fines for Overstaying EU"

Hey HN! I built this after I nearly got hit with a €1,200 fine at Barcelona airport for miscounting my Schengen days.

The 90/180 rule is confusing - it's not just "90 days then leave." It's a rolling 180-day window, and every trip counts even if you left and came back.

Existing calculators were clunky or behind paywalls, so I made this: - Clean, mobile-first interface - Tracks multiple trips automatically - Shows exact reset date - Works offline - 100% free, no signup

Built for digital nomads, but useful for any non-EU travelers visiting Europe.

Happy to answer questions or get feedback!
