Verdict

The call

The clearest difference is price: STI Tx Guide at Free against ASCVD Risk's $2.99. STI Tx Guide also leads on rating (3.5 vs 1.0) and update cadence (every 2 months vs every 19 months). ASCVD Risk's advantage is review sentiment (67% vs 36%) and iOS requirement (13.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

STI Tx Guide holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: STI Tx Guide has 36 ratings behind it against 1, 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 67% of ASCVD Risk'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, ASCVD Risk every 19 months. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
