Glad you are liking that feature! That particular feature took the most time of any feature in the 2.0 update.

I am also extremely happy with this update. Thanks! So many quality of life improvements and big features. Wow!

I'd heard on the Geosphere Forums that your customer support was second to none and now I know the rumours are true!!
I hadn't properly connected the Location icon with the GPS as I was under the impression that Location came from multiple sources (incl internet routers, wifi & GPS). If it's that clearcut, then you've just locked me onto another important tool for managing battery performance in the field.
Thanks also for the Airplane Mode tip - hadn't hooked into that one either!!
Think I'll go back to the Geosphere Forum now and see if I can drum up some more customers for you - you deserve them 

Correct. You can even test this by being in Cachly, then locking your phone. When you press the power button again (still on lock screen) you can wait until the location icon in the status bar turns off. This means GPS is no longer being used.
Yes, GPS switches back on if you unlock your phone and are back in Cachly.
Another tip to save battery life is to turn your phone to Airplane Mode. Since iOS 8 you have been able to use GPS while in Airplane Mode. This will also really save on battery.
I will still add the GPS on/off idea to our feature list. I think it is a valid request that we will explore. Thanks!

Not at this time. We are a very small development team, so we are focusing on iOS at the moment. 
If that changes we will be sure to announce it. 

Great job Nic! 
I absolutely love it!!!
