Notesnook is a free, easy-to-use private notes app and organizer. It is fully cross-platform – automatic and instant syncing of notes between your computer, tablet and mobile. Its unique feature is that all notes are encrypted with military grade encryption by default. A built-in App Lock locks the App with fingerprint so no one can peek into your private notes on your device. You could double encrypt your notes for really confidential information. Locked notes require password on open and are encrypted at rest. You can get things done with to-do lists and tasks and keep track of your daily progress to accomplish daily tasks.
