# Chegg Study vs Mastering Spectroscopy

The clearest difference is rating: Chegg Study at 4.7 against Mastering Spectroscopy's 3.3. Chegg Study also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (205K vs 6). Mastering Spectroscopy's advantage is review sentiment (40% vs 20%) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Chegg Study sells 4 in-app purchases, starting at $15.99 per month and Mastering Spectroscopy sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chegg Study holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: Chegg Study has 205K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 20% of Chegg Study's written reviews are positive against 40% of Mastering Spectroscopy's, so the app with the better star average is not the one people write more warmly about.

Chegg Study ships an update every 3 weeks, Mastering Spectroscopy every 4 months. The most recent releases landed on October 16, 2026 and September 30, 2026 respectively.
