# ShakeAlarm vs EarthQuake+

The clearest difference is review sentiment: ShakeAlarm at 100% against EarthQuake+'s 45%. ShakeAlarm also leads on in-app purchases (none vs 3) and ads (none vs shown). EarthQuake+'s advantage is rating (4.6 vs 3.5) and ratings volume (2.3K vs 2). On price, update cadence and device support there is nothing between them.

Both are free to download. EarthQuake+ sells 3 in-app purchases, starting at $0.99 per month. ShakeAlarm asks for nothing beyond the download.

EarthQuake+ holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: EarthQuake+ has 2.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of ShakeAlarm's written reviews are positive against 45% of EarthQuake+'s, so the app with the better star average is not the one people write more warmly about.

ShakeAlarm ships an update every 2 months, EarthQuake+ every 3 months. The most recent releases landed on October 9, 2026 and October 27, 2026 respectively.
