LifeDigger is a personal knowledge database/personal wiki, where you can write about everything you learn or see in your work / interests. But unlike many note apps where you end up with 5000 static notes that you will probably never see again, you can easily search and review notes in LD. You can even use Flashcards and spaced-repetition to deepen your recollection of these notes. LD is meant to be intuitive, fast and put the focus on building an actual knowledge on your topics of interests.
