Got the latest update installed and it's looking good. A few small things I've noticed:
If the GPS is turned off then your last location doesn't show up on the map nor does the location of any of the people on the map. I could see the app using your last location and showing ppl around you. If the GPS is turned off a popup notification letting the user know it's turned off maybe helpful also.
Once I turned my GPS on I noticed that my location updated, but when I was zoomed out it appeared my location was flickering from my current location to my last location about 10 miles away. After I zoomed in though the issue seemed to go away.
Under notifications:
Why is the delete message and deny friend under the same entry? I may want to delete a msg, but not deny a friend.
I deleted a msg, but the message didn't disappear until I switched off the screen and to another.
When I selected your message and selected show friend it showed an icon, but it was the same color as my icon. The sorta teal color, instead of the green, yellow or gray for a normal user.
I sent a test reply and the text box has the text vertically aligned in the middle instead of the top.
Also, I sent you a friend request. We are in separate parts of the globe though.

The username is mprindle.
