Way better than OneNote for handwritten notes. You can write a massive, mile-long page and the app won’t break when you try to export it as a PDF. It exports everything exactly as you wrote it without cutting anything off, unlike OneNote, which often cuts off your notes during export.

I feel thus could be a great app..but why in the world is it premium to (text) notes...that makes no common sense i mean if I wanted a drawing app I'd get flippa clip but this says "take notes" and I gotta come outside pocket for it...like at least mabyee a better version with other upgrades but taking notes dude??
