# Notefuel vs Study Sets

The clearest difference is rating: Study Sets at 5.0 against Notefuel's 4.7. Notefuel's advantage is ratings volume (311 vs 13) and iOS requirement (12.0 vs 17.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Notefuel sells 2 in-app purchases, starting at $15.95 per month and Study Sets sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Study Sets holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Notefuel has 311 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 87% of Notefuel's written reviews are positive against 91% of Study Sets's.

Notefuel ships an update monthly, Study Sets every 4 weeks. The most recent releases landed on September 28, 2026 and September 8, 2026 respectively.
