Ever wanted a geologist to ride along and explain what's outside your window?
Being a geologist myself, I went on vacation and wished I had someone to read geologic map descriptions as we drove across the countryside. When I got home, I started working on Backseat Geologist to do just that!
Backseat Geologist will give you audio descriptions of the rocks below your feet or wheels as you travel.
- Browse the geologic map and tap around to see details about the geologic units that are near you
- Start an Explore session and get updates on the geology below you as you move around
- Overlook Mode scans the geology of what you can see and tells you all about it
- Create Routes to listen to the geologic story of your commute, road trip, or family outing. Routes combine the context of each geologic unit you pass to create a more cohesive set of descriptions.
- Routes can be saved offline for areas with bad service
- Long tap on the map to drop a pin and tap again to create a route to that location
- Adjust descriptions for any audience from kids to geology enthusiasts
- Geology data is powered by Macrostrat geologic database
- Plays from the background and doesn't interfere with navigation or other apps
- Works well with other playing audio like music or podcasts
- Widget for the geology of your current location
- App Intent gives Siri access to geology information from the app without opening it.
Premium and Max users get:
- Improved audio quality
- Download geologic map tiles and data for areas of the map to use offline
- Custom route creation
- Import GPX files in custom routes
- See further in Overlook Mode
Download Backseat Geologist and discover the millions and billions of years of earth history rolling by your window.
