# Calvim vs Roozane

The clearest difference is in-app purchases: Calvim at none against Roozane's 3. Calvim also leads on review sentiment (96% vs 80%) and ratings volume (491 vs 45). Roozane's advantage is update cadence (every 9 days vs every 5 weeks). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. Roozane sells 3 one-off in-app purchases. Calvim asks for nothing beyond the download.

Calvim holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Calvim has 491 ratings behind it against 45, so its average is the more settled of the two. Written reviews point the same way: 96% of Calvim's written reviews are positive against 80% of Roozane's.

Calvim ships an update every 5 weeks, Roozane every 9 days. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
