| Where it stops | Free positions can lag by minutes and satellite coverage, voyage history and route forecasts are all paid features. | The free tier carries ads and keeps only about seven days of flight history; longer playback, filters and weather layers need a subscription. | A new account unlocks one region free; the one-off region packs were withdrawn in 2025, so everything beyond it is now a Premium subscription. | Only about a hundred cities are supported — outside them it has nothing to offer. |
