I didn't know about Bear. Just had a look on their website and the application and user experience looks pretty stunning.
However, I am not quite sure it justifies paying for this service when Apple Notes has got a lot better in the past few years (I also feel confident in the privacy approach of Apple).
Out of curiosity, what features make you use Bear and not Notes? I take a lot of notes, and if something can make my life easier, I would seriously consider making the move.
