About Quillpad
Quillpad is a free, open-source Android app for taking notes in Markdown. Users can organize notes into notebooks, add tags, create task lists, set reminders, and attach files or voice recordings. It is a fork of the Quillnote app, whose development stopped, and the project is licensed under GPL-3.0.
Notes can be synced to a local or cloud folder as Markdown files, backed up to a zip file, and restored later. Sync with Nextcloud is listed as experimental and requires the Nextcloud Notes app on the server. The project states that the app shows no ads, does not ask for unnecessary permissions, and does not upload notes without the user knowing. Cloud folder and Nextcloud sync are optional and send data to external storage.
