My life is pretty disorganized with stuff at school, work, and extracurriculars. For a few months now I've been encouraged to get a planner instead of keeping it all in my head. Now don't get me wrong, I love taking physical notes and doing homework on paper with my nice pens and such. However, I do need a planner that syncs from my phone, laptop, and desktop.
I've been scouring for an open source solution to all this and a few months ago, I found Super Productivity. It had pretty much all of what I needed, places to put down tasks, a pomodoro timer, clients for desktop and mobile, and a place to see my progress. I didn't use its syncing features though, because, it only allows dropbox, webdav, and local file sync. I thought it was pretty incomplete.
Over the course of this week I realized that I had a NAS that I could access outside of home so I could sync everything with my synology drive folder, allowing uploading and downloading of the .json file across all my devices. This works extremely well and very seamlessly. Now, I have a completely open source solution that doesn't really ping any servers apart from saving a .json file locally and then syncing to my server. It's a dream come true and works works amazingly.
After seeing how much this piece of software has transformed my life, I am hoping to share this and hope you guys will start using it as well and support this dev. Planners usually cost me around $10 or so, I'll probably give the dev at least that much once my paycheck rolls in.

You can store them wherever you wish. I put them in my documents folder. You can specify the folder path in the sync settings.
