About this app

Point your camera at a landmark you can see on the horizon (eg. Mountain peak, Road, Lake, Building, Airplane) and see:
- Name of the landmark
- Distance from you
- Altitude (& relative to you)
- Map of surrounding area
- Nearby towns and cities
- Wikipedia info for any landmark with a Wikipedia page
- Altitude, destination, flight number, airspeed of any commercial airline plane
- Directions to landmark (opens in google maps)
- Street view for where you're pointing (opens in google maps)

Or use 3D Map mode:
- See terrain and hills laid out in front of you
- Move phone to fly around the map
- Roadmap / satellite / hybrid
- Search & display 3D-maps for anywhere worldwide
- Distance, altitude and landmark names
- Markers on hill & mountain peaks
- Infinite scroll

Horizon Explorer works worldwide, but works best on top of a hill with an unobstructed view of your surroundings. You can drag the horizon line with your finger to line up with the camera if the automatic tracking is not working very well. Or try waving your phone around in the air in a figure 8, then press "align using compass" to calibrate the compass.

Live airplanes: Enable planes from the settings menu, then point at a plane to see the flight number, origin, destination, altitude and current airspeed of any commercial airline plane you can see.

If you are in a tall building, or otherwise not standing on the ground, enable "Tall Building mode" and optionally set your altitude using the slider.

Horizon Explorer will show mountain & hill peak names, lakes or forests, the names & designations of roads, and many buildings.

Wikipedia Information will be displayed for anything that has a Wikipedia article with a location set on the article.

Difficult to use. Display on screen does not match the images in the description. The description shows the word distance and the word altitude. I see something like a ruler laying at a 45 degree angle that might indicate distance and there's some kind of vertical bar that might indicate altitude. but the distance is definitely wrong I pointed at a house across the street that's a hundred fifty feet away and its reporting less than 70. there is a half circle at the bottom of the screen that I have no idea what it's supposed to do. There's also a yellow blotch that sort of floats around on the screen but no description of what it's supposed to do sometimes a strawberry like red icon pops up and floats around I have no idea what that indicates.

You're right those are distance and altitude. Try pointing at something on the horizon and the distance will be more accurate. It's much more useful when you have a view of the horizon. Try it somewhere with a decent view (on a hill) and you'll find it works a lot better. We've added a tutorial - hopefully it explains how it works.

The planes feature would be interesting if it wasn't such a money grab. Why so much money?! Per minute!? I can get live tracking data free elsewhere... Why not at least a trial mode so we can see what we would be buying? By the way, I'm not a cheapskate... I simply want to know what the feature does / looks like without having to pay a fee (for only 10 minutes of use at that). Maybe someone has a video of it on YouTube, but your reply doesn't really encourage me to pay... Thanks for the rude remark.

Works perfect. Loved it. But that would be sp great if you can add the inverse location find option. I mean that user select a location from map and ar presentation shows selected location on screen. But again it is a great app. Thanks a lot

In the 3D map mode you can search for places and see a 3D terrain map of that place. In AR map mode, if you chose another location the white AR terrain outline wouldn't match what the camera could see? Can you send more detail about your feature request to hello@horizon-explorer.com? Glad you like it, thanks for the review!
