# Distance and Height Telemeter vs T

The clearest difference is rating: Distance and Height Telemeter at 3.0 against T's 2.5. T's advantage is update cadence (every 3 months vs every 12 months) and review sentiment (19% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Distance and Height Telemeter holds the better App Store score, 3.0 against 2.5. That said, the two scores are not equally well evidenced: T has 33 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of Distance and Height Telemeter's written reviews are positive against 19% of T's, so the app with the better star average is not the one people write more warmly about.
