I’m chipping away at bugs and adding features to my app Reminder Sync for Obsidian! https://turquoisehexagon.co.uk/remindersync/

Currently working on supporting dataview tasks format and multiple reminder lists.

The app supports any markdown backed notes app, but I fear I may have limited its appeal by including Obsidian in the app name.
