# Mochi vs StudyPDF

The clearest difference is rating: Mochi at 4.6 against StudyPDF's 4.0. Mochi also leads on in-app purchases (none vs 5) and ratings volume (175 vs 1). StudyPDF's advantage is review sentiment (100% vs 81%) and update cadence (every 9 days vs monthly). On price, ads and device support there is nothing between them.

Both are free to download. StudyPDF sells 5 in-app purchases, starting at $5.99 per 7 days. Mochi asks for nothing beyond the download.

Mochi holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Mochi has 175 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of Mochi's written reviews are positive against 100% of StudyPDF's, so the app with the better star average is not the one people write more warmly about.

Mochi ships an update monthly, StudyPDF every 9 days. The most recent releases landed on October 29, 2026 and October 31, 2026 respectively.
