# Alarm Free vs S

The clearest difference is rating: Alarm Free at 3.3 against S's 1.0. Alarm Free also leads on ratings volume (13 vs 1). S's advantage is review sentiment (75% vs 35%) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

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

Alarm Free holds the better App Store score, 3.3 against 1.0. That said, the two scores are not equally well evidenced: Alarm Free has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 35% of Alarm Free's written reviews are positive against 75% of S's, so the app with the better star average is not the one people write more warmly about.

Alarm Free ships an update every 29 months, S every 2 months. The most recent releases landed on October 31, 2026 and November 4, 2026 respectively.
