# VIIO vs Reading Roo

The clearest difference is ratings volume: VIIO at 1.2K against Reading Roo's 24. VIIO also leads on rating (4.7 vs 4.4) and review sentiment (68% vs 50%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. VIIO sells 10 in-app purchases, starting at $2.99 per month and Reading Roo sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

VIIO holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: VIIO has 1.2K ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 68% of VIIO's written reviews are positive against 50% of Reading Roo's.

VIIO ships an update fortnightly, Reading Roo monthly. The most recent releases landed on September 24, 2026 and August 12, 2026 respectively.
