This is awesome! Does it work in EU as well?

Does this also recognize peaks as well as PeakFinder does?

Great work! One of those apps that scratch the itch!

This is really well done! My 9-year-old and I have been going down the rabbit hole for the last 2 hours. We simply love the ‘Where it formed’ feature. Great job!

This is timely. I am on my way to the Grand Canyon today. Will install and give it a go with my son. I think he will be excited.

Very well done. The animation of plate movements give me a real sense of vertigo! Earth is old. o__O

For me at least, it would feel more intuitive to have the distant past on the left and the current date on the right. I'd also love an option to keep the current location centered while manually dragging the slider.

EDIT: Also, could optionally overlay lat/lon lines to help anchor the globe as it rotates? It's hard to understand the plate movements relative to the Earth.

It's a cool idea but how do you know whether it's accurate? Couldn't it just be making stuff up? Laymen consumers would have no way to tell the difference.

Is there a web version? I don't like to install apps if avoidable.

When the page loads, it shows a blinking animation [1]. I didn't realize it was a loading an interactive background example. Perhaps load a default photo of the grand canyons and add a clock or something until the full version loads.

[1] In my phone in the subway, not a very good WiFi nearby.

Very cool. Does this mean any chance AR features are coming to Flyover Country? I've used that app for years, but matching what I see onto the map is the trickiest part.

Super cool, congrats! I've played around with the android app, works great and it's really interesting!

Very cool project! I also wonder if a web version is plausible. Are there any specific native app features in it?

This is very cool! Great use of augmented reality. Now have a narration mode that gives you LLM-based Roadside Geology explanations of what you’re seeing as you drive.

Very cool. Really like having the soils and quaternary layers for those us in the Midwest without a lot of bedrock exposure.

No WAY I have wanted this exact thing all for years!!! I am so stoked to try this out later. This is so sick.

Got the test flight version installed no problem!

I don't see it on the Play Store for my Pixel 11. There are two marked "Outcrop" but not by these people.

Whenever I try live view I get "tracking did not start. Try again" on android

Shameless other project plug: if you have a flight coming up and are a window seat fan please try out https://flyovercountry.app ! it has a similar augmented reality view so you can figure out what you're seeing out the airplane window (and a bunch of other fun features)

This would be insanely awesome if I could add a data layer or two atop the geologic unit map. This combined with processed ASTER and LANDAST data overlaying the geologic units would make surficial mineralogy so much more exciting when you're out in the field.

This is very interesting!! I just pointed at a landscape from a high ground and it said this river was formed around 460million years ago! Which it seems is that old in earth’s life!

I hope to one day try it. I'm an hour south of Mpls. It would be interesting to use it on one of those super-deep gravel pits in rural Goodhue where one can see ten stories of earth. Good luck.

US only?

atleast re-write your subheading "each rock named" most ai smelling shite ever.

Neat idea. Does it work offline? Up north there's often no signal, and I'd guess phone compass drift near steel bridges or cliffs would throw the overlay off too.
