When I saw this app, I was excited to try it out. I've been using Dreams for a while, and Journey as my daytime journal. I was more than willing to pay for the full version, but unfortunately, Monomo just doesn't have all the features I need to be a replacement for Journey. That's not the app's fault, don't get me wrong, it's just the way things currently stand.
First of all, I have been using Journey for over a year, maybe even two, and there's no way to import the entries from there, not even just text. Not that I would know how that could be implamented. Secondly, there's no formatting. I don't need much, just a simple bold, italic, and underline, but the app doesn't have that. Lastly, the tagging is a little less intuitive than Dreams's signs feature. You can add tags with categories, link them, add triggers, and all that the same. Except when you create a new tag while writing an entry, there's no way to select its category right away. So then you have to do the tedious process of categorizing your tags post-entry.
Other than that the app is really good, a good journaling app with a similar style to Dreams, which I love and will continue to use. And I think this app would be good for anyone who wants a simple journaling experience with good organization (I really like the tag feature.) But in its current state, Monomo just isn't for me.
