# Whiz Reader vs ivySCI

The clearest difference is review sentiment: ivySCI at 80% against Whiz Reader's 0%. ivySCI also leads on ratings volume (9 vs 1). Whiz Reader's advantage is rating (5.0 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Whiz Reader sells 1 one-off in-app purchase and ivySCI sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Whiz Reader holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ivySCI has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Whiz Reader's written reviews are positive against 80% of ivySCI's, so the app with the better star average is not the one people write more warmly about.

Whiz Reader ships an update every 2 weeks, ivySCI fortnightly. The most recent releases landed on August 13, 2026 and September 10, 2026 respectively.
