William Hill

Behind a library step, under a fountain ledge, wedged into a hollow oak, a tiny logbook is waiting, and the only record of where you have already looked is whatever you can remember. Built for casual and dedicated geocachers alike, this app keeps a private map of every find spot in one place so the next visit never starts from scratch.

Tap to drop a pin where you searched, give it a name, and jot down what actually mattered: micro cache, tricky muggle traffic, log book running low. Tap any pin to reopen its full detail, and delete pins once a cache is retired or moved. Used right after a find, while the container, the terrain, and the warnings for a friend are still fresh, it slowly becomes a personal atlas of a hobby otherwise scattered across memory and other people's logs.

There is no login, no location tracking beyond the pins you place by hand, and no ads. Just your pins, on your phone, private to you.
