# Klein Tools Borescope vs TempPro

The clearest difference is rating: TempPro at 4.2 against Klein Tools Borescope's 1.8. TempPro also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (533 vs 57). Klein Tools Borescope's advantage is review sentiment (12% vs 4%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TempPro holds the better App Store score, 4.2 against 1.8. That said, the two scores are not equally well evidenced: TempPro has 533 ratings behind it against 57, so its average is the more settled of the two. Written reviews complicate that: 12% of Klein Tools Borescope's written reviews are positive against 4% of TempPro's, so the app with the better star average is not the one people write more warmly about.

Klein Tools Borescope ships an update every 4 months, TempPro every 3 weeks. The most recent releases landed on October 4, 2026 and October 11, 2026 respectively.
