Kate0508:
Happy to share the results of my "search" so far. I need to be able to store the notes locally — on the device for iOS, iPadOS, macOS — as well as the cloud. This is how Evernote works and is a must for me as I need constant access to my data regardless of internet connectivity.
I have looked at Notion [ https://www.notion.so ], and was initially quite impressed by it. I emailed them regarding local storage syncing to cloud. Here is their response: "We don't currently support local storage. Currently our data is being saved on the Notion server so everyone must be online for all your data to sync on all your devices. And, we don't have "full offline" capability at the moment, but it's the direction we're headed. We definitely want you to be able to use Notion on the go!"
And I have also looked at "Keep It" [ http://reinventedsoftware.com/keepit/ ], and am impressed by it. I emailed the same question and here is their response: "On Mac, Keep It always keeps the files locally. On iOS it will download them on demand, unless you enable the option to download them all automatically…you will obviously need enough space on your device for all that data."
Thank you!
John
