Verdict
The clearest difference is in-app purchases: KOOBONE at none against Readingo's 1. Readingo's advantage is ratings volume (118 vs 3) and review sentiment (93% vs 83%). On price, rating, update cadence and ads there is nothing between them.

On the App Store both sit at effectively the same score — 4.8 for Readingo against 4.7 for KOOBONE. That said, the two scores are not equally well evidenced: Readingo has 118 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 93% of Readingo's written reviews are positive against 83% of KOOBONE's.
Readingo ships an update every 9 days, KOOBONE fortnightly. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
