Ratings and Reviews

Very Versatile!


I love how versatile this app is! I originally bought it for research projects in my classes and it's been wonderful for that. I've been able to carry around all of my notes and not worry about leaving any of them behind. I think the app has helped me be more efficient academically, especially because of how easy it is to see how my notes relate to each other, but I'm really excited about how I can use it for other things too. I just began to use it for a personal genealogy project to track my family tree/history. The timeline feature has been great for me to see the big points and events in my family line. I think this is a great app.


The new update lets you organize the cards yourself. The text formatting is nice, but it would be great if we could use color in addition to the bold, italic, and underline options. One of the last updates added category colors to the subject cards. That was a useful addition. The app is pretty good. It is getting better. I am looking forward to future updates!

Nice and useful, but...


It REALLY needs a desktop version, with sync.
This is a really useful app, I've been looking for something like this for a long time (as a grad student in the humanities -- lots of citations, etc.), and this does the job very nicely. The only drawback, which is a huge drawback for me, is that I can only use it on my iPad, although the majority of writing I do still occurs on the computer. Yes, the rtf export works, but it's not extremely useful, as I can't update the database from my desktop.
So please, please, do come up with something for the desktop.

Great concept - No sync


I reviewed this app previously, and favorably. However, I can no longer use this app until sync is solved. When my iPad crashed, fortunately, I had exported my last set of research to evernote, but it is in rtf! Yuck! The extensive research data for a particular set of topics I am researching would have to be built from scratch from a huge set of ‘cards’ or tagged notes. I have moved back to a less brilliant app, but I do miss the unique, filtering/sorting that Ilaro provided.

Don’t let it stump you, you have a kernel of greatness here. I’ll revise to 5 stars once iCloud sync (or any sync) is solved.
