# Study Stack vs HyNote

The clearest difference is in-app purchases: Study Stack at none against HyNote's 14. Study Stack also leads on review sentiment (100% vs 77%) and rating (5.0 vs 4.8). HyNote's advantage is ratings volume (7.5K vs 2) and chart position (#107 vs unranked). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. HyNote sells 13 in-app purchases, starting at $4.99 per 7 days. Study Stack asks for nothing beyond the download.

Study Stack holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HyNote has 7.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Study Stack's written reviews are positive against 77% of HyNote's.

Study Stack ships an update fortnightly, HyNote every 9 days. The most recent releases landed on June 4, 2026 and September 28, 2026 respectively.
