How are the carrier locks implemented today? I assume it must be implemented on the client (phone). Do the carriers work with all the phone manufacturers to have them add this capability?
I recently discovered How We Feel so I just wanted to thank you for your work. I really enjoy using the app!
I found a small bug in the analyze tab though. If you look at e.g. weekly and select a tab that is not the left most one, then scroll down, then tap the top of the display (the universal scroll to the top feature of iOS), the content disappears.
