There are several decent note apps that strive to replace Google Keep, but they all seem to fall short on the one feature that keeps me on Keep: Reminders. Being able to jot a note and have it pop up later today, on the weekend, or on an arbitrary recurring schedule is the primary use-case for me. Joplin's come the closest but the reminders were unreliable, and an unreliable reminder is a useless reminder.

There's also something to be said for the number of clicks/menus/presses it takes to create a note. If it's meant to be just a quick note when something pops into your head then it's nice if it doesn't take more than a click or two to get it down.

One last thing. A feature that I think would greatly enhance adoption would be an option to import existing Keep notes from a Google Takeout into your Simple Notes.

I pitched Redline to my partner as "It's a racing movie but they cranked the 'anime' knob up to 11. It's great." They loved it.

Thank you for that link. I found that page to be quite enlightening.
