Denkzettel Companion is a Windows companion program for the Android App Denkzettel
Denkzettel is an excellent Android app by Silvio Schurig for writing notes as text files and organizing them into categories (= subdirectories) on an Android smart phone. It can also use these files as check lists.
Denkzettel Companion is a Windows Program that I have written with Lazarus. It tries to mimic Denkzettel on the Windows platform. The idea is to synchronize the notes between an Android device and a Windows PC and have similar programs on both platforms to edit them.
