# TempGrapher vs Beyond Oximeter

The clearest difference is price: Beyond Oximeter at Free against TempGrapher's $0.99. Beyond Oximeter also leads on rating (2.0 vs 1.0) and ratings volume (76 vs 1). TempGrapher's advantage is review sentiment (27% vs 13%). On update cadence, ads, in-app purchases and device support there is nothing between them.

Beyond Oximeter is free to download; TempGrapher costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Beyond Oximeter holds the better App Store score, 2.0 against 1.0. That said, the two scores are not equally well evidenced: Beyond Oximeter has 76 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 27% of TempGrapher's written reviews are positive against 13% of Beyond Oximeter's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
