Personally I love the idea of unlimited writing paper, especially for studying biology, medicine related subjects. I appreciate the use of apple’s innate writing system, which somehow shows a prettier writing than the ones on apps like notability/GoodNotes. However, the lack of lasso select function is honestly very annoying, almost discouraging. There’re multiple times I want to move a segments of writing to another location for better idea categorizing, but I can’t. I even purchased the premium upgrade, because I thought this function is included based on the description of “expanded pencil tool”, but it’s not.Speaking of the upgrade, I haven’t experience a major user improvement with the $7 premium upgrade. The shape function, at least for me, is meh. I don’t mind having an imperfect circle or arrow. I don’t really need that much extra pencil setting space on the side. Maybe there’re more functions available, but I haven’t find them as useful nor necessary (which I understand this is why the upgrade is optional).Overall, it is a great app even without the upgrade. I can see it having lots of potential becoming a more mainstream productivity app. However, I really hope it can implement some sort of cloud backup option (even one way backup to the third party app like google drive could be helpful), and please please include the selection function I mentioned.
