There are some helpful aspects about the app, but I am really frustrated with the rapid log. I understand that the point is to use your bujo, so the app only saves your rapid log info for 72 hours. However, since I don't use the app all the time, I forgot that I made some notes when I was away from my BuJo. Now those notes are gone. That's on me, sure, but it is hard to have so many tools and apps where it functions as an extension of your brain then to use one that has such a limited memory.
