Torque Source holds the better App Store score, 3.1 against 2.0. That said, the two scores are not equally well evidenced: Torque Source has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 14% of Torque Source's written reviews are positive against 67% of Torque Tightening's, so the app with the better star average is not the one people write more warmly about.
Torque Source ships an update every 8 days, Torque Tightening every 9 months. The most recent releases landed on August 19, 2026 and September 15, 2026 respectively.
