What's New in SpyglassBeacon
1.4.0
August 7, 2026
Beacon now warns you everywhere it counts. - Alerts when you approach a line: nearing 183 in a state, or running low on Schengen days, Beacon tells you — even with the app closed. - Schengen forecast: the card now shows when you get a day back, or when an overstay ages out. - New clocks: the FEIE 330-day foreign-presence test for US expats, and Canada's 1,095-day citizenship presence count. - Clearer status line and upfront pricing on the welcome screen. Your location history still never leaves your device.
