# Alertable vs ShakeAlarm

The clearest difference is rating: Alertable at 4.7 against ShakeAlarm's 3.5. Alertable also leads on ratings volume (179 vs 2). ShakeAlarm's advantage is review sentiment (100% vs 61%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Alertable holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Alertable has 179 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of Alertable's written reviews are positive against 100% of ShakeAlarm's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 9, 2026 respectively.
