Verdict

The call

The clearest difference is rating: IDSA Practice Guidelines at 4.8 against STI Tx Guide's 3.5. IDSA Practice Guidelines also leads on ratings volume (559 vs 36) and iOS requirement (12.0 vs 15.0). STI Tx Guide's advantage is review sentiment (36% vs 0%) and update cadence (every 2 months vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

IDSA Practice Guidelines holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: IDSA Practice Guidelines has 559 ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 36% of STI Tx Guide'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.

UpkeepUpdate frequency

STI Tx Guide ships an update every 2 months, IDSA Practice Guidelines every 7 months. The most recent releases landed on August 28, 2026 and September 28, 2026 respectively.
