Build a Multi-Country Visa Window Route Planner for Long-Term Travelers

1. 1

   Start with the Schengen clock

   The 90-in-180 rolling window is the anxiety every European nomad shares and the single feature that earns the install. Get that calculation perfect, with entry and exit dates, before anything else.

2. 2

   Add the popular corridors

   UK, Balkans, Southeast Asia, Latin America: each has its own visa-free windows. Cover the routes nomads actually run so a whole year of travel fits in one plan.

3. 3

   Plan forward, not just track backward

   The killer feature is 'if you go to Portugal in May, you must exit Schengen by this date; here are nearby non-Schengen options.' Suggestion, not just arithmetic.

4. 4

   Keep rules current and cite them

   Visa policy changes. Date-stamp every rule, link official sources, and state clearly that final authority is the border, not the app. Accuracy is the entire reputation.

5. 5

   Charge the planner, not the calculator

   A free single-zone calculator earns trust and search traffic; the paid tier is multi-country planning, alerts, and passport-specific rules.

6. 6

   Grow where nomads gather

   Nomad forums, coliving communities, and travel-planning groups are dense with people asking exactly this question every week. Answer it publicly and link the tool.
