Comments on Readbook - Text, Image Reader for Android
★★★★★Ben Aldhouse· Aug 17, 2025
This gets 5 stars for being the 1st out of MANY that I have tried for the purpose of opening and searching a massive txt file quickly & efficiently. I've needed this functionality for ~20 yrs, & in spite of computers & sw supposedly getting better over time - finding an app that does this gets harder. I am thankful to the developer for supplying an app that is vastly better than the next best. I would pay to go ad free & more options for search (case-sensitive at least) would be nice.
