I went down that rabbit hole once and it’s really hard to find a foss app that is enjoyable to use and actively maintained. Condution (https://www.condution.com/) seems to be one of them but I never tried it as it looks a bit too much for what I personally need.

Not open source but e2e encrypted and privacy focused is lunatask (https://lunatask.app/). They have a free plan and you can get access to the iOS beta (the app is fully functional). I don’t used it anymore but I paid for Lunatask and it helped a lot making order in my brain and switching from bloated apps to a more minimal todo approach. It’s highly opinionated, but it implements more than one “method”.

Currently I’m using https://github.com/sodenn/2do-txt because I switched to the todo.txt method, which better fits my need for a more minimal approach to those things. The app has ios/macOS version (with tauri build replacing electron) and you can sync with whatever you want (i use syncthing).

Hope it helps, the todo landscape on ios is a nightmare.

Sorry! I did not see the notification. So appflowy I think is desktop only for now, but afaik there is work in progress to bring it on mobile https://github.com/AppFlowy-IO/appflowy-editor/issues/68

As for silverbullet, the app is basically a PWA so if you have a server you can theoretically run it there and access it anywhere. I never tried but I heard people even collaborating, so. I had access to testflight beta for iOS, but I believe at one point the developer decided to focus more on stability and less on multi-platform releases, but I’m not sure. They have a discord channel where they are very active though.

Just trowing here other two open-source alternatives: https://silverbullet.md/ (Obsidian-like) and https://appflowy.io/ (Notion-like)

Nice, I will try it out. As others have said, seems more a Notion-like than an Obsidian alternative, but still a nice tool. Since using obsidian for more than a year I am used to having my markdown notes visible in my folders and access them also outside the application itself, but I saw I can export them from anytipe in markdown. I’ll give it a try and see how it goes.
