I think this App needs it's own thread where we can share our experiences and give feedback.
I picked up a Sony Xperia E1 yesterday from Dick Smiths. It is a prepaid on special and cost only $48.
That is a good start because it makes it cheaper than a Canmore, possibly even after paying for the App, and it promises to do oh soooooo much more!
I am also trying to get one of the great looking waterproof arm bags that Roo recommended with the waterproof headphones.
Not being an Android user I has a few issues with basic things, like turning the GPS on!

James sorted me out (big thanks) and pointed me to a User manual which always helps!

I sat the GPS in the backyard for about 30 minutes. When I went back to check if it has a fix it shows 4 or 5 sats. But the moment I picked it up and started walking around with it it dropped it 1 or 2 sats and stopped giving speed readings (as it should).
I walked around getting worried about this for a few minutes, then decided to put it back down in the yard again to see what it got. It immediately jumped to 4 or 5 sats. Great, I thought. It may work when stationary but not while moving. Thats not going to much good for us.
While I was watching it the sats display suddenly lit up with 15 satellites!!!!
Fifteen! I have NEVER seen a GPS lock in that many sats!! It didn't take long to realise that this GPS must be able to use the Glonass system as well. It must have just taken a long time to sort itself out and download the almanacs.
I went for a walk and it was working as I had expected it should. It displayed 15 to 16 sats locked as I walked up the street and back holding it out in front of me at chest level. The location accuracy said it was 4m most of the time and I saw 3 a few times.
Now that I am inside my Kitchen, it is still showing connection to 5 or 6 sats. There are a couple of windows right next to me, but that is quite amazing. Locational accuracy is now only 232 meters though. As I typed that, it jumped to 7 sats and said 13 meters.It must be quite a sensitive chip and not a bad antenna.
One problem I have with the phone is that the screen won't stay on for more than about 30 seconds without me touching it all the time. I may be able to find the setting to change this.
Another thing: When I walked really slowly it stopped showing speed. I suspect Manfred has set it to discard 1 kmh. If he has, it may not record distance below that either.
I recorded a loop around my street walking exactly in the gutter. It will be interesting to see how the location map looks (when I figure out how to get the file out. That is the next big challenge!)
So far this device and app seem to be doing what they should. More to follow.
