Best notes app

I’ve used a lot of notes apps trying to find the perfect one. This is it! Sync, encryption, export, markdown, attachments, this one has it all ands then some!

Web clip option

Been looking for a simple(ish) notes app to get nahstee Google Keep out of my IPhone and Android phone life, syncing between each phone and which will save web pages. This fills that need better than anything else I’ve found so far and as a very small use retiree on limited funds the reasonable free tier is great for this use case. Hopefully my recommendations to others will give more of a lucrative return!

Truly the very best notes app!!!

I love this app, it’s fast, has many options, the very best, you won’t find a better app!!!

Moved from Standard Notes

Always been looking for the perfect note application. I wasn’t Evernote user for multiple years and switched to other applications but they all are too heavy. Started using Standard Notes. Was lightweight, but there are a lot of issues with the application. So now I’m happy with Notesnook because it has all the features I need and appears to be reliable. Only issue is I could not import my Standard Notes into it so I have been slowly moving them over manly.
