Hey guys, i'm looking for an open-source TimeTree alternative: one shared calendar with per-event/person colors that show the same on Android and iOS.

Self-hosted (Nextcloud/CalDAV) is fine; one app preferred.

CalDAV seems to sync only calendar colors; Google’s per-event colors don’t travel via CalDAV and iOS ignores them. Is there any FOSS client or Nextcloud frontend that can reliably render per-event colors (e.g., from CATEGORIES/ATTENDEE) across platforms?

Not interested in “one calendar per person” or proprietary apps. Any pointers appreciated. Thanks!

Hey Guys,

I' m searching for a good replacement of TimeTree.

I think Nextcloud is nearly what i'm looking for but i the App situation on Android is a big problem for my sourroundings. Like i have to install 2 apps?

Any hint or help would be a pleasure!

Thank you!
