5 stars! 80% of my life was and is spent on reading. I've tried a lot of apps and readers out there but the one that stuck to me for 4 years now is FBreader. Easy to use. It's not perfect  when i remove Memory Card all the bookmarks vanish. Still  the reading experience on this is glitch free. I appreciate that its free abd without ads. The team is has done a great job. Kudos. Sending my love to all of you for this great app.
