I use Obsidian for this. I create template notes for each activity with all the checkboxes, then when it’s time to do the activity I just go “Create new note from template” and choose the right template.

AnyType is an open-source alternative to Notion which recently launched:

That’s what beeper.com does. It’s also open source, but they handle running it for you.

But absolutely I agree that it doesn’t remove WhatsApp from your life, and that’s a pain point for me also when I’m working with services in Asia, who like Brasil predominantly work from WhatsApp.

If you don’t like Beeper, you could try these guys who host a managed solution (means you don’t have to deal with any issues), and let’s you offer the service to others:

You can use a FOSS app at your end to chat with WhatsApp users, if this isn’t something you’re already aware of. Element.io plus a bridge. Beeper.com is a turnkey platform that sorts it all out for you.

It doesn’t help replace WhatsApp as a platform, but perhaps it would suit you?

How in the world is that 17%? TIL I also like unpopular movies.
