A simple, fast, clean, and free without ads app. This is one of the most functional, easy to use PDF readers. There are not many features like Adobe Acrobat or others, but it is best for PDF reading. You can read and annotate with it. There are four different ways to adjust the pages, which is helpful. However, I wish there would be a dedicated reading mode that adjusts the pages and fonts, so we could read without straining our eyes.

Very useful. If anyone wants to become self publisher and sell their ebooks on their own then this app with drumlin security publisher window app is the solution for you. This app and drumlin security admin windows can replace Amazon KDP Kindle publishing and help earn more money without sharing royalty with anyone, but you own have to manage all the ebook selling.

Our company has been using Javelin for about 3 years. We find it very good, particularly these newer versions that have much improved rendering speed and general "smoothness" compared to the javelin2 readers we had started out with near the end of 2015. We also commend the staff on their responsiveness and level of support. When we have queries or need help with issues they typically reply within 25 minutes. We've even managed to convince them to add some new features just by mentioning them! If you're looking for a secure PDF generator/reader I would wholeheartedly recommend the drumlin/javelin combination.

Just a terrible reader. I understand its purpose is to prevent piracy but going from something like Kindle to this is horrendous. The desktop version is worse. You can't scale text, zooming doesn't auto resize the page to fit, any notes or highlights you make, you're forced to bookmark as they're no aggregate data for notes and highlights (completely useless on the desktop version as you can't even bookmark on the desktop version). I'll never use Boson again because I'm forced to use this

Shocking software. Not user-friendly at all. Have an encrypted PDF and have to use this program. Have requested refund for PDF even though contents are good as this program makes it a chore to access.

App won't even launch. Crashes as soon as I launch it.

Problem I faced: You have a Pdf file in WhatsApp, when you will open the PDF in this app, okay till now, then you wanted to open another PDF in your WhatsApp, you will press back, But, you will know that your WhatsApp is actually the Javelin App, Now there is not any other solution to close WhatsApp and restart it to open the next Pdf. It does not deserve any stars. Totally Waste of time. Totally Garbage. Don't install
