LogMyTop (Gipfelbuch) is an app to log your personal targets for memory, and makes it easy to scroll through the events even after many years. You can share your tops with friends and family and bodies. One can review the tops and open the top books even if one is already at home. The app is allowing you only at the top to enter sheets into the top logbook (verified by GPS). You can find other people which where on the top and are going on the top. Your entries can be absolute private, shared with App bodies or in the App environment.
