Installed it, found out I needed to sign up for a 7-day trial. Ok, I'll give it a shot...but then I was told that I have to provide payment info first, before I try the app. I'll have 7 days from activation to cancel. Forget it--really hate these "we'll hold your money hostage and hope you forget to cancel in time" schemes. This may be a wonderful app, but when the devs have so little confidence in their product that they resort to tricks, I have very little incentive to find out.

Downloaded app, started free trial subscription and cancelled subscription all on the same day. 7 days later, I am charged $21.09 for a one year subscription. My request for a refund was denied by Google Play (even though they cancelled my subscription as of July 22 - the same day I was charged). So they get my $20 and I get nothing. Easy to rank in the top 10 grossing when you're ripping people off this way. Notice that the developer does NOT even respond to any of the reviews left here.

I really enjoy the app. It's nice being able to track the record of what I have found, easily document the location and day of find. My only feedback would be that it typically wants to show that even diamond registers as quartz. That is the only flaw I found so far. It is nice having a well detailed description of all the different types of Fossil, rock, and minerals.
