ReceptionRating · Positive reviews · Number of ratings

Chippy Tools holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Chippy Tools has 905 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 82% of Hague Screw Thread Calculator's written reviews are positive against 55% of Chippy Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hague Screw Thread Calculator ships an update every 2 months, Chippy Tools every 8 days. Both last shipped on October 16, 2026.
