STI Tx Guide holds the better App Store score, 3.5 against 2.2. That said, the two scores are not equally well evidenced: STI Tx Guide has 36 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 38% of How To Use Inhaler's written reviews are positive against 36% of STI Tx Guide's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

How To Use Inhaler ships an update every 5 weeks, STI Tx Guide every 8 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
