# Alpha CLOUD vs Bookster

The clearest difference is review sentiment: Bookster at 77% against Alpha CLOUD's 0%. Bookster also leads on ratings volume (258 vs 1) and update cadence (every 2 weeks vs every 2 months). Alpha CLOUD's advantage is in-app purchases (none vs 10) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Bookster sells 9 in-app purchases, starting at $24.99 per month. Alpha CLOUD asks for nothing beyond the download.

Alpha CLOUD holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Bookster has 258 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Alpha CLOUD's written reviews are positive against 77% of Bookster's, so the app with the better star average is not the one people write more warmly about.

Alpha CLOUD ships an update every 2 months, Bookster every 2 weeks. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
