# Prodrafts vs ivySCI

The clearest difference is ratings volume: Prodrafts at 3.8K against ivySCI's 9. Prodrafts also leads on update cadence (every 4 days vs fortnightly) and rating (4.8 vs 4.6). ivySCI's advantage is review sentiment (80% vs 70%) and iOS requirement (15.5 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Prodrafts sells 2 in-app purchases, starting at $6.99 per year 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.

Prodrafts holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Prodrafts has 3.8K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 70% of Prodrafts'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.

Prodrafts ships an update every 4 days, ivySCI fortnightly. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
