Haven't used WebDAV services. I'll focus on local import/export for now since it's on early development stage. I'll be listing features suggested though for tracking.
Well not everyone remembers everything, even the most important things. Just like me, who always forgot where I put my smartphone after a couple of seconds, or even my partner's birthday. I'm the worst at remembering.
Import and Export features are already planned. You would choose your preferred backup/export directory because I know that android data directory cannot be accessed by many especially on newer android versions.
It's FOSS, offline, no account required, and others in the future. I honestly don't know much about Monica since I don't use it. I don't use web services that has a free and offline alternatives.
It's on early development so there's not really a huge difference.
Got it! I'll consider this.
