Bookoscope is a fast, searchable ebook catalog. With Bookoscope, you can browse your own self-hosted ebook library as well as download public domain classics from Project Gutenberg. FEATURES: - Fast - Easy on the eyes - Includes over 70,000 public domain books from Project Gutenberg - Uses cached feeds (refresh on demand) - Searchable by any available metadata - Quick download and export to the ereader of your choice COMPATIBLE WITH: - Calibre-web - Kavita - Ubooquity - Any ebook server with OPDS 1.0 functionality WHY USE BOOKOSCOPE? Some ereader apps can connect to OPDS endpoints, but the functionality is tucked away and awkward. There's no way to browse and search all the ebooks you have access to, all at once. Bookoscope fills that niche. It crawls your OPDS endpoints, finds and caches all the books it can, and lets you easily download any of them to your device. From there, you can export them to your preferred ereader. BOOKOSCOPE IS NOT: - An ebook reader, sync client, or annotator, like Apple Books, Google Books, or Kindle. - A metadata editor or organizer, like Calibre. - A self-hosted ebook server, like Kavita, Ubooquity, or calibre-web. Bookoscope may be used with any of the above, but is not affiliated with any other app or tool. WHAT IS OPDS? OPDS is the open standard for web endpoints that expose catalogs of ebooks. Many people use home OPDS servers for their personal ebook libraries. WHAT IF I DON'T HAVE AN OPDS SERVER? That's okay! You can use Bookoscope to browse and download free, completely legal books in the public domain. Start with classics like: - Moby Dick - Frankenstein - Pride and Prejudice - The Great Gatsby - The complete works of William Shakespeare, Charles Dickens, Frederick Douglass, and more!

Verdict
The clearest difference is review sentiment: TotalReader Pro at 70% against Bookoscope's 0%. TotalReader Pro also leads on ratings volume (220 vs 1) and chart position (#165 vs unranked). Bookoscope's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 2). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
TotalReader Pro costs $6.99 and Bookoscope $2.99 up front. TotalReader Pro sells 2 one-off in-app purchases. Bookoscope asks for nothing beyond the download.
Bookoscope holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: TotalReader Pro has 220 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of TotalReader Pro's written reviews are positive against 0% of Bookoscope's, so the app with the better star average is not the one people write more warmly about.
TotalReader Pro ships an update every 4 weeks, Bookoscope every 5 days. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
