Love but dose have some problems. Hate that for i think two weeks everything is free to use then after that the basic things are blocked and you have to pay. The hyperlink only works when turned to gesture mode,have to click on pen to turn that on. The notebooks they give you are nice, i mainly use the sticker that came with the notebook. I love that it is one time purchase just wish that they had backup instead of converting things to pdfs.

when i knew this app could add pictures, and that i could put them where i want, i freaked out. this is the best app that i found, and i was looking for something like that the entire day. and the best thing about the "in-app purchase" is that it's just ONCE!!! you guys did a very good job, this app is really clean, beautiful, easy to use, it has really good features, and now i can have my online bullet journal just like the tradicional bullet journal :)

Please add the option to expand or stretch PDF margins! When annotating dense documents, we desperately need extra blank space on the left and right sides to write notes directly next to the text (similar to Notein's canvas expansion). Flexcil is amazing for stability, but this one feature would make it complete. Please consider adding it in a future update!
