What is a good location-based game for Android?

I am looking for a good location-based game for Android.

I have Ingress already, but due to my work schedule and obligations to my wife, i have little to no time to actually go out and play with a group, so i am looking for something I can play alone.

I used to play "Own This World" and really enjoyed it, but the server shut down last year. It was like an IRL Risk where you automatically drop a troop into a territory you are physically occupying every 30 seconds and can use resources generated from the controlled territories to launch attacks in any territory you are in to gain control of it.

I have been trying similar games like "Claim Your Area", "Qonqr", and "The Great Land Grab", but they require constant attention to get territories and there isn't very many other players in my area. Also, i don't really have easy access to monitor other players territories to compare myself to them.

"Life is Crime" and "Skirmish" seem interesting enough, but the same problem with the other two I mentioned exists and they use buildings and shops rather than territories.

"Parallel Mafia" and "Parallel Kingdom" were cool, but the "Free to Play, Pay to Win" aspect was really annoying and made it unplayable after a week or so.

I used to do Geocaching, but after finding pretty much every cache close by and not having enough time anymore to check out any others, it has no longer become an option.

Does anyone know of any other games not mentioned that are worth trying?
