I never cared much for Geos. Putting a Chevy emblem on them didn't help much, either.
I just downloaded an app for this and it seems there are a few in my area but a lot of them require the premium account.
Geocaching.com has all the caches listed for free. I have never paid for anything for geocaching, my gps app is free, I don't usu the official geocaching app though so i have to look up coordinates on the website and enter them into my app. It takes about a minute.
That's the site I used and it doesn't list it all on the site or the app.
