“Antinote is a productivity scratchpad exclusively for macOS. It's meant for temporary notes, calculations, and quick text manipulation; and designed to be beautiful, fast, keyboard-driven, and privacy-first.

Antinote is built with a clear purpose: to be the perfect companion for temporary notes, quick calculations, and light text manipulation. It’s not trying to do everything — it’s trying to do a few things extremely well.”

For me, I love to have a plain text “scratch pad” on my laptop and phone. Right now I use:

• Plain Text Editor (on MacOS)
• Edit (on iPhone)

This seems like it could be an interesting replacement?
