# Emergency Central vs boostEM

The clearest difference is review sentiment: boostEM at 100% against Emergency Central's 63%. boostEM also leads on in-app purchases (none vs 2) and update cadence (every 3 weeks vs every 9 months). Emergency Central's advantage is rating (4.8 vs 4.6) and ratings volume (55 vs 9). On price, ads and device support there is nothing between them.

Both are free to download. Emergency Central sells 2 in-app purchases, starting at $99.99 per year. boostEM asks for nothing beyond the download.

Emergency Central holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Emergency Central has 55 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 63% of Emergency Central's written reviews are positive against 100% of boostEM's, so the app with the better star average is not the one people write more warmly about.

Emergency Central ships an update every 9 months, boostEM every 3 weeks. The most recent releases landed on October 17, 2026 and October 10, 2026 respectively.
