I like the idea, but does no one else have serious concerns about privacy? Yes, the required permission to monitor your usage of other apps seems reasonably well-motivated by the stated purpose of classifying your phone usage as focused vs unfocused phone. But on further consideration, that' actually a ton of information to sign away in exchange for growing some digital trees. I'll just stick to a simple timed alarm until I see some assurance that our usage data isn't being sold to 3rd parties.
