This is a cool idea. I see it as a great utility for taking newer versions of photos years later or even just remembering where you parked.

Curious though when I installed it I only see kilometers but the screenshot on the website shows imperial units and I don't see any way to change it. Is there a way?

Edit: yeah just found the swipe to change units. I'm all for supporting apps and developers but $2 just to switch units? No thanks. Uninstalled. That's insane.

Edit 2: the biggest issue about the price is perceived value. Making this app cost $.99 or $1.99 itself? Not bad in my opinion. Development isn't free and I probably would have paid that. But when you move to an in-app purchasing model now the perceived value is a free app that is gouging you $2 just to switch from metric to imperial. Maybe the intent was to have as many people try it as possible and to hopefully make a little money from it but the way the in-app purchasing is structured it makes me feel like I'm being taken advantage of.
