Sinister Kettlebell holds the better App Store score, 4.0 against 3.6. Both are backed by a comparable volume of ratings — 30 and 28 respectively. Written reviews complicate that: 67% of Sinister Kettlebell's written reviews are positive against 84% of StrongFirst'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 weeks. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
