# MySirenum vs Temper

The clearest difference is rating: Temper at 4.6 against MySirenum's 2.5. Temper also leads on update cadence (every 4 weeks vs every 3 months) and ratings volume (97 vs 4). MySirenum's advantage is review sentiment (41% vs 9%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Temper holds the better App Store score, 4.6 against 2.5. That said, the two scores are not equally well evidenced: Temper has 97 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 41% of MySirenum's written reviews are positive against 9% of Temper's, so the app with the better star average is not the one people write more warmly about.

MySirenum ships an update every 3 months, Temper every 4 weeks. The most recent releases landed on November 1, 2026 and November 13, 2026 respectively.
