# Lab Values Reference Guide vs MED

The clearest difference is review sentiment: Lab Values Reference Guide at 89% against MED's 0%. Lab Values Reference Guide also leads on in-app purchases (none vs 11) and iOS requirement (9.3 vs 15.1). MED's advantage is rating (4.7 vs 3.1) and update cadence (every 2 months vs every 7 months). On price, ads and device support there is nothing between them.

Both are free to download. MED sells 11 in-app purchases, starting at $8.99 per 7 days. Lab Values Reference Guide asks for nothing beyond the download.

MED holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: MED has 210 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 89% of Lab Values Reference Guide's written reviews are positive against 0% of MED's, so the app with the better star average is not the one people write more warmly about.

Lab Values Reference Guide ships an update every 7 months, MED every 2 months. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
