Before ✗
- Slow travelers plan a year of one-to-three-month stays by cross-referencing climate tables, visa rules, and vibes.
- The Schengen 90/180 rule turns a pleasant plan into a compliance problem.
After ✓
- Every city gets a 12-cell month strip — one glance answers “is March good here?”
- A ranked “this month” view, deep per-city sheets, and an editable year-builder with a live Schengen meter and shareable URLs.
- Scoring is transparent and re-weightable: travelers can optimize for weather, cost, air, or safety.
