Can one of you recommend a good and easy calender app and task app, which can be synched over CalDav to my next cloud calender and task app? The apps in nextcloud look preety helpfull, but it is not really feasible without any Smartphone usage. Tasks.org seem to be not free of charge, when changing to Caldav support.
Currently we are using family wall, but also this app needs a pro version, which is really expensive.
Thanks for yout help
