# STAT!Ref vs IDSA Practice Guidelines

The clearest difference is rating: IDSA Practice Guidelines at 4.8 against STAT!Ref's 2.8. IDSA Practice Guidelines also leads on ratings volume (559 vs 5) and iOS requirement (12.0 vs 15.5). STAT!Ref's advantage is review sentiment (36% vs 0%) and update cadence (every 3 months vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

IDSA Practice Guidelines holds the better App Store score, 4.8 against 2.8. That said, the two scores are not equally well evidenced: IDSA Practice Guidelines has 559 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 36% of STAT!Ref's written reviews are positive against 0% of IDSA Practice Guidelines's, so the app with the better star average is not the one people write more warmly about.

STAT!Ref ships an update every 3 months, IDSA Practice Guidelines every 7 months. The most recent releases landed on June 8, 2026 and September 23, 2026 respectively.
