# AHS EMS vs Thrombosis

The clearest difference is rating: AHS EMS at 5.0 against Thrombosis's 4.0. Thrombosis's advantage is review sentiment (75% vs 34%) and update cadence (every 5 months vs every 11 months). On price, ratings volume, 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.

AHS EMS holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 2 and 3 respectively. Written reviews complicate that: 34% of AHS EMS's written reviews are positive against 75% of Thrombosis's, so the app with the better star average is not the one people write more warmly about.

AHS EMS ships an update every 11 months, Thrombosis every 5 months. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
