# Hear Boost vs EMF Analytics

The clearest difference is in-app purchases: EMF Analytics at none against Hear Boost's 18. EMF Analytics also leads on update cadence (every 2 days vs every 3 weeks) and review sentiment (66% vs 50%). Hear Boost's advantage is ratings volume (12K vs 72) and rating (4.2 vs 4.0). On price, ads and device support there is nothing between them.

Both are free to download. Hear Boost sells 15 in-app purchases, starting at $2.99 per 7 days. EMF Analytics asks for nothing beyond the download.

Hear Boost holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Hear Boost has 12K ratings behind it against 72, so its average is the more settled of the two. Written reviews complicate that: 50% of Hear Boost's written reviews are positive against 66% of EMF Analytics's, so the app with the better star average is not the one people write more warmly about.

Hear Boost ships an update every 3 weeks, EMF Analytics every 2 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
