About & Pics

Description

Point your camera at a landmark you can see on the horizon (eg. Hill, Mountain, Road, Lake, Building) 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
- Direction from you (eg. Northwest)
- 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 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
- 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 pressing "align using compass" to calibrate the compass.

Live airplanes can also be enabled, starting from $0.99. Point at a plane and 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 names, lakes or forests, the names & designations of roads, and many buildings.

Wikipedia Information will be displayed for anything that has an English Wikipedia article with a location set.

This app uses Google's ARCore to do augmented reality. This technology is currently available on ~50 phones: https://developers.google.com/ar/discover/supported-devices

If you don't already have the latest ARCore app installed, you will be prompted to install / update it from the Play Store when you first open Horizon Explorer.
