I gave up Evernote several years ago, after many years of being a dedicated user. But with over 20,000 notes in my database, it was unbearably slow, couldn't be searched, wouldn't fit on my hard drive on one computer (you can sync all or none), and every time I had any issues (as you do with a database that large) support's answer would be to delete the database off of my device and resync it, which would take 3-7 days to complete. And in the meantime, I couldn't do anything.

I tried several other solutions, and quickly found that any program that uses a proprietary database to store notes was a problem. And too many of them have no way to get your notes back out of the database except copying and pasting one at a time.

I currently use Apple Notes to quickly capture information since Apple makes it easy to share to Notes and have it immediately synced between all of your Apple devices, but I don't use it as a notes repository. I save each note as pdf, docx, or text/md in my file system. If something gets corrupted, it is one single file, it doesn't put everything in a 20,000 note database at risk. Never again will I have to figure out how to transition 20,000 notes into another format.

BTW if you have an Apple Pencil, you can create a new note just with a tap on your lock screen. So easy!
