Before I go into the actual question, let me give you some context. I am running my own instance of ownCloud which allows me to host my own CalDAV server among other things. I use an app called SolCalendar that is able to sync calendars with my phone but does not sync tasks.
I am looking for an app that is able to do a two-way sync of tasks with a CalDAV type server. This app must have its own user interface (aka please do not suggest this app to me. It does not have its own UI and requires another app to function properly).
- Must be able to do a two-way task sync with any CalDAV server (e.g. I must be able to insert my own URL to the server)
- Must have its own user interface
- I don't necessarily care how it looks, as long as it has the basic things a task app should have
- Should be free, but its not a major requirement
