Ratings and Reviews
Just downloaded this app
I use this for online school but I do have to save the web pages (lessons) as PDFs in order to use this app, which is not a big deal bc iOS makes it so simple. After using it for a couple of hours, I can already say, the free version is soooo good, I’m bout ready to buy the pro version. Well done. PLEASE keep up the good work. All I would change is that when you want to add a comment, it should just show the input box instead of having to click “add comment” and THEN the input box shows up. Also more color options for highlighting.
I was using Weava before this, and between that app and this one, this one takes the cake. Awesome. I just wish they would add more color options like Weava. I’m bouncing between both apps because I love that I can choose whatever color I want on Weava.
I want to like this but I don’t
I really like the highlighting capabilities, when they work that is. Plain highlighting usually works ok, but little details have bugs. Like, say I have a highlight that spans multiple pages. Half the time, that doesn’t work, and some strange area vaguely related to what I selected ends up being highlighted. So I have to delete the highlight and try again. Usually I end up making two separate highlights. Or, say I select some text and I end up missing a word or two, so I want to expand the selection. Good luck getting that to work. It’s easier to delete the selection and try again. And again. But I could deal with little nits lick that if only the app could remember what location I’ve read up to in the document. I don’t know how many times I’ve read 10 or 20 pages of a document, then come back the next day, and the app places me on page one again, and I have to figure out where I left off. Then I read another 10 or 20 pages, come back the next day, and the app puts me on page one again. So, I wrote to the developer to ask for help with that. No response. Nothing. I like the idea, but this app doesn’t feel complete. I see the other reviews and I wonder how they aren’t seeing the same problems I am.
More colors and connectivity across devices than you think
I incidentally found out that I have more color options by re-highlighting different colors over each other. Makes my notes much prettier. In addition, I was on the go once with only my phone, not my tablet. I was easily able to sync up to my tablets progress and pick up where I left off since I saved it to the iCloud. Thank goodness for this feature! Saves me time and gives me relief to be able to use this app to keep track of all my research articles for school. Now if I can only figure out how to use some type of subfolders to organize everything even more…
