ReceptionRating · Positive reviews · Number of ratings
TempPro holds the better App Store score, 4.2 against 1.7. That said, the two scores are not equally well evidenced: TempPro has 603 ratings behind it against 70, 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 6% of TempPro's, so the app with the better star average is not the one people write more warmly about.
UpkeepUpdate frequency
Klein Tools Borescope ships an update every 4 months, TempPro every 3 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
