# ShakeAlarm vs Earthquake Tracker

The clearest difference is rating: Earthquake Tracker at 4.5 against ShakeAlarm's 3.5. Earthquake Tracker also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (77 vs 2). ShakeAlarm's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 75%). On price, ads and device support there is nothing between them.

Both are free to download. Earthquake Tracker sells 3 in-app purchases, starting at $3.99 per 7 days. ShakeAlarm asks for nothing beyond the download.

Earthquake Tracker holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Earthquake Tracker has 77 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 75% of Earthquake Tracker'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 Tracker every 2 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
