# SubtleSTEMI vs CorePendium

The clearest difference is rating: CorePendium at 4.9 against SubtleSTEMI's 4.2. CorePendium also leads on update cadence (monthly vs every 8 months) and ratings volume (1.5K vs 9). SubtleSTEMI's advantage is review sentiment (100% vs 62%) and monetization model (free vs freemium). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CorePendium holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: CorePendium has 1.5K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of SubtleSTEMI's written reviews are positive against 62% of CorePendium's, so the app with the better star average is not the one people write more warmly about.

SubtleSTEMI ships an update every 8 months, CorePendium monthly. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
