# TotalReader Pro vs Bookoscope

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.

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.
