Hi all! I'm Maureen, the maker of SeniorEase Library. I built this app because I kept buying books I already owned and I couldn't find a tracker that was simple enough without being ugly or bloated. SeniorEase Library does one thing well: scan an ISBN, it's in your library. No account, no ads, no subscription. Just your books. Try the first 10 books for free at seniorease.eu I'd love to hear what you think!
