# SideBooks vs Poste

The clearest difference is review sentiment: SideBooks at 72% against Poste's 0%. SideBooks also leads on ratings volume (97 vs 1) and update cadence (every 9 days vs every 2 months). Poste's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.

Both are free to download. SideBooks sells 1 one-off in-app purchase. Poste asks for nothing beyond the download.

Poste holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SideBooks has 97 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 72% of SideBooks's written reviews are positive against 0% of Poste's, so the app with the better star average is not the one people write more warmly about.

SideBooks ships an update every 9 days, Poste every 2 months. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
