    Project mention: Show HN: See what country you would hit if you went straight (1 BC → Present) | news.ycombinator.com | 2025-08-20

    This app is designed to answer my wife’s question “what country would we hit if we went straight” (generally posed while pointing)

    Two additional features:

    1. Load up historical maps from different years (right now 1 BC, 700 AD, 1000 AD, 1300 AD, 1800 AD, 1900 AD) and see what you would hit if you had a time machine AND you went in the direction your phone is pointing

    2. Tap a country/territory for an (AI-generated) blurb on what you are pointing at

    Notes:

    1. Here’s how it works: starting from your phone’s bearing, we trace the great-circle in 200 km steps, prefilter candidate countries with bounding boxes (~5–10 instead of ~200), then check ~20 km points along each segment to catch coastlines and stop when the path first enters another country.

    2. Great-circles (https://www.movable-type.co.uk/scripts/latlong.html) are why you can hit Australia from NYC, even though when you look at a flat map that can be hard to see.

    3. There might be some weird stuff in the explanations, I haven’t read all 1,400 of them. If you see something weird let me know and I will update it!

    4. The app is free and doesn’t have ads or tracking — your location and bearing are only used locally to figure out where you are and what you’re pointing at

    5. Probably will work best if you hold your phone pretty flat
