Verdict
The clearest difference is rating: AHS EMS at 5.0 against Lanthier's 3.8. AHS EMS also leads on in-app purchases (none vs 2) and iOS requirement (12.0 vs 16.0). Lanthier's advantage is review sentiment (62% vs 34%) and update cadence (every 2 months vs every 11 months). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Lanthier sells 2 in-app purchases, starting at $19.49 per year. AHS EMS asks for nothing beyond the download.
AHS EMS holds the better App Store score, 5.0 against 3.8. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews complicate that: 34% of AHS EMS's written reviews are positive against 62% of Lanthier'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, Lanthier every 2 months. The most recent releases landed on September 20, 2026 and September 10, 2026 respectively.
