I'm just stunned 😹

A couple days ago I contacted the developer for the original version of this app (AGR tools) I had used the app for a few hours and found out it didn't support upcoming iOS 11 so they contacted me and I'm glad to know it's here and better than the old version


Great program

I was worried that the program ARG Tools was going away because of the update to OS 11. It is now better than ever. This is an excellent program. Thanks for updating it.

I’m so stoked by this app. It’s amazing how much information and useful tools are inside. I will be using it for Geocaching as well as educating myself.
