Simplenote

Simplenote is one of the best note-taking apps with the cleanest and most user-friendly interface. To use Simplenote, all you need to do is open it, jot down some thoughts, and you're done!

Besides its interface, this app also stands out for many other features, including:

• Sync everything across all your devices: Automatically sync seamlessly across any computer, phone, or tablet; Back up and sync everything as you take notes.
• Collaborate and share: Allow you to share ideas with a colleague, or write a grocery list with your roommate; Choose whether to publish your content to the web, and share a link with whoever you want; Publish directly to a WordPress site by connecting your WordPress.com account.
• Stay organized with tags: Instantly find what you’re looking for with keyword highlighting.
• Stay safe: Protect your content with a passcode lock.

However, as a result of prioritizing simplicity, Simplenote doesn't support handwriting-to-text, sketching, and lacks cloud sharing. But these cons are overlooked by Simplenote's users since they mostly only want a simple digital notebook they can carry around and take quick notes.
