# Lanthier vs MedCalX

The clearest difference is monetization model: MedCalX at free with in-app purchases against Lanthier's subscription. MedCalX also leads on ratings volume (30 vs 5). Lanthier's advantage is review sentiment (62% vs 46%) and update cadence (every 2 months vs every 5 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Lanthier sells 2 in-app purchases, starting at $19.49 per year and MedCalX sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 3.8 for Lanthier against 3.7 for MedCalX. That said, the two scores are not equally well evidenced: MedCalX has 30 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 62% of Lanthier's written reviews are positive against 46% of MedCalX's.

Lanthier ships an update every 2 months, MedCalX every 5 months. The most recent releases landed on September 10, 2026 and September 25, 2026 respectively.
