# Calzy vs SideNotes Mobile

The clearest difference is price: Calzy at $1.99 against SideNotes Mobile's $9.99. Calzy also leads on rating (4.7 vs 4.2) and update cadence (every 2 days vs monthly). SideNotes Mobile's advantage is in-app purchases (none vs 3) and review sentiment (88% vs 77%). On ads, monetization model and device support there is nothing between them.

Calzy costs $1.99 and SideNotes Mobile $9.99 up front. Calzy sells 3 one-off in-app purchases. SideNotes Mobile asks for nothing beyond the download.

Calzy holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Calzy has 1.9K ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 77% of Calzy's written reviews are positive against 88% of SideNotes Mobile's, so the app with the better star average is not the one people write more warmly about.

Calzy ships an update every 2 days, SideNotes Mobile monthly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
