# Readingo vs KOOBONE

The clearest difference is in-app purchases: KOOBONE at none against Readingo's 1. KOOBONE also leads on rating (5.0 vs 4.8). Readingo's advantage is ratings volume (117 vs 2) and update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

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

KOOBONE holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Readingo has 117 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 93% of Readingo's written reviews are positive against 82% of KOOBONE's, so the app with the better star average is not the one people write more warmly about.

Readingo ships an update weekly, KOOBONE every 3 weeks. The most recent releases landed on October 19, 2026 and October 20, 2026 respectively.
