It is a extremely good markdown citizen - you can type in GitHub flavoured Markdown and it has no issues whatsoever. I have a lot of notes apps, but ones that respect markdown, whilst being fast at search are hard to find. It also has quick shortcuts for todays date, supports checkboxes (and a filter so you can have one giant to-do). But really, it's the speed that you'll stay for. That also means speed of sync across devices (iOS/MacOS). It even has multiple themes (multiple dark modes, for those who are interested). The build in tagging support is powerful, and allows you to create tags anywhere in a document, it doesn't need to be formatted in a specific way, the sidebar will capture all of the tags created. Finally, it has excellent exporting support - HTML, Markdown, .txt. You'll be able to share your notes, easily.

I really like how Bear uses iCloud to sync my notes across my iPhone and Macbook. Bear has constant updates that bring great features, such as new themes, a feature to lock certain notes with a password, and the ability to tag certain notes into sub groups.

Bear is a beautiful app. I love the ability to easily create different types of lists, break up my notes with titles, and include code and photos. The ability to change skins and app icons is also a nice touch.
