Great note-taking app!
Exactly what I am looking for
This is the app I’ve been waiting for so long. My favorite feature of this app is that it allows me to hand write notes on a separate notebook while reading and annotating a PDF document.
Flexcil does all I need. Many thanks to the developers!
Easy to use and helpful.
This app just easy and simple to use and it saves a lot of time where I just need to carry my iPad without heavy textbooks for my works.
Great app for researchers!
This is a purposely designed app for digital note taking and documents highlighting/underlying. The ultimate purpose for these activities is to assist learning, memory and information retrieval. Flexcil allows one to perform these activities with minimal effort using gestures and these gestures are easy to learn and intuitive.
Great app for reading + annotating + taking notes at the same time.
The app is great for reading + annotating + taking notes at the same time. I really like that I can freely move the notes anywhere on top of the PDF, annotate with gesture, move annotations around, share notes across different PDF files, look up words in the dictionary, keyword search in PDF, etc. I highly recommend the app!
