You already have a note you'd never let anyone read
Passwords. Medical results. The thing you still haven't said out loud. It all went into a notes app without much thought — and you have never once checked who else can read it.

Start it on your laptop, finish it on your phone
The same notes, seconds apart. Encrypted before they leave your device, so what travels is gibberish to everyone but you.

Have been using @notesnook for some days now and loving it. Notesnook says they can't read my notes and that was enough to convince me to use it. Will mostly buy a subscription after my free trial ends. Do check it out!

You simply cannot get any better of a note taking app than @notesnook. The UI is clean and slick, it is feature rich, encrypted, reasonably priced (esp. for students & educators) & open source.

Notesnook app is what Evernote should have become long ago. And they're still improving.
