Life Chain
Read full descriptionHide full description
"Life Chain" offers you the chance to document your life. After using the application, no one will be able to tell you what you remember or forget, what you recall correctly, or what you remember incorrectly. The app allows you to enter promises you made to yourself, memories you shouldn't forget, gifts you gave to your friends, and events that were important to you. This way, you can revisit these events later and differentiate between what you remember and what you may have forgotten. It provides an opportunity to refresh your memory. By entering the events you are experiencing these days into the app, you can also look back on them in the future.
