# EMS Calculator vs AEMT PASS

The clearest difference is price: EMS Calculator at $0.99 against AEMT PASS's $21.99. EMS Calculator also leads on iOS requirement (6.0 vs 17.6). AEMT PASS's advantage is rating (2.4 vs 1.8) and update cadence (every 6 months vs every 16 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

EMS Calculator costs $0.99 and AEMT PASS $21.99 up front. Neither carries in-app purchases, so what you see is what you pay.

AEMT PASS holds the better App Store score, 2.4 against 1.8. That said, the two scores are not equally well evidenced: AEMT PASS has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 25% of EMS Calculator's written reviews are positive against 22% of AEMT PASS's, so the app with the better star average is not the one people write more warmly about.

EMS Calculator ships an update every 16 months, AEMT PASS every 6 months. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
