Verdict
The clearest difference is price: STI Tx Guide at Free against Lab Values Pro's $0.99. STI Tx Guide also leads on review sentiment (36% vs 0%) and ratings volume (36 vs 3). Lab Values Pro's advantage is rating (4.0 vs 3.5) and device support (3 vs 1). On update cadence, ads and in-app purchases there is nothing between them.

STI Tx Guide is free to download; Lab Values Pro costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Lab Values Pro holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: STI Tx Guide has 36 ratings behind it against 3, 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 Lab Values Pro's, so the app with the better star average is not the one people write more warmly about.
STI Tx Guide ships an update every 8 months, Lab Values Pro every 10 months. Both last shipped on November 11, 2026.
