I searched quite a bit and wasn't able to find a conclusive list of available third party apps that can sync with Nextcloud. So I thought I'd start one for folks who might be interested. Feel free to chime in with any you've used!

Notes

macOS:

• Nextcloud Notes Client - looks exactly like Apple Notes, but syncs with NC and supports Markdown.

Linux:

• Iotas - minimalist markdown notes app in the same vein as IA Writer.

Android:

• Quillpad - Google Keep clone that supports Markdown. Fork of Quillnotes. There are some quirks with this one. For example, if you create a task list from NC WebUI version of Notes, the checkboxes will show up in Quillnotes, but you cannot check them off as complete. Has a promising roadmap.

• Carnet - another Google Keep clone. This one has an app in the NC app store, so it has a web based counterpart unlike Quillpad. The Android app is weirdly slow to open. I'll need to test this one more.

Tasks/ToDo

Android:

• Tasks.org - excellent Task app. Supports subtasks, categories, reminders, recurring events. It can also sync with Google but ewwww.

Handwritten Notes:

All:

• Saber - Cross platform notes app. Akin to Samsung notes. This one is rough in my experience so far. But it has potential and I will be following to watch how it updates.

2FA:

Android:

• Aegis - excellent 2FA app. I just recently migrated out of Google and Microsoft's versions and am very happy. To be honest though, I'm not exactly sure how the NC integration works on this one, but it is mentioned on their site:

If your cloud provider supports the Storage Access Framework of Android (like Nextcloud does), it can even create automatic backups to the cloud.

There are others I've tested, but not long enough to make any comments on. Les Pas being one of them. I'm happy with Immich, so didn't give this one a fair shake.
