Snail: Walking Away From the Inevitable

Field notes

The stated game loop combines device location, Apple Health step counts, and proximity notifications: the snail advances toward the player's actual position, while recorded walking pushes it back. The page says the pursuit continues with the app shut and begins at two miles per day before accelerating each week. It also states that the project requires no account, advertising, tracking, purchase, or shared data, with an iPhone running iOS 16 or later listed as the target.
