Overall good app, needs more pen presets

Overall after paying to remove ads this app is very useful and allows me to conveniently highlight and annotate pdfs.

However, it is annoying to constantly switch between pen colors, thickness and opacity depending on whether I am writing or highlighting, etc. If we could have 2-3 pen presets up there similar to apps like Adobe sketch, it would be more convenient and simulate a real environment in which you can easily grab your highlighter or different colored pens without changing many settings. (The highlight text option doesn't always work because many pdfs are scanned pdfs rather than editable ones, in which case I use thick pen size with modified opacity as a "highlighter"). I also find it difficult to write annotations by hand even in the smallest pen size, and often have to type them instead, so if the writing could be a bit more natural and allow smaller sizes (which you could then use when you zoom in to a PDF) that would help a lot.

As an app developer though, great work overall! The Dropbox and other connections are super useful.

Excellent app

We love using this app to study our English and Russian publications side by side(instead of having to open and close different apps for reference or a book and the app). The only reason I don’t give it 5 stars is because it can get a bit frustrating when having to constantly switch between each note taking, writing, page turning, highlighting+opacity etc. instead of just DOING the task. I end up making a lot of mistakes because I forget to switch back to a different tool. Hopefully my thought is easily understood.

Fantastic App

I came across this app quite by accident. I was looking for a way to see if my iPad Air 2 could facilitate a split screen so that I would be able to see English and Creole version of PDF files. I thought I was going to have to purchase an upgraded expensive tablet to achieve my goal. I read all the previous reviews first, then downloaded free version. I was convinced, so I upgraded to pro version without the ads. Having a built-in tutorial would help immensely. Thank you.
