I didn't realize they own Day One! That really stinks. It's a great app, but his childish antics make me question the wisdom of relying on it. I wonder if I can get a prorated refund.
I'll second that Day One is a great app... I've used it nearly every day for the past 13 years. I was afraid it would stagnate after it was acquired by Automattic, but it's only gotten better.
Day One is really nice. I actually prefer Apple's Journal app, but for some reason they don't want to put it on the iPad which makes no sense to me. IMHO, Journal should have been an iPad-first app.
Until Apple does that, I'll likely keep using Day One.
I was thinking more about the features unique to the iPad. With the Pencil you could sketch and doodle and hand write the entries. I think that would make it feel more personal and, if the benefits of writing by hand are true, more valuable.
