# STS Timing vs CRUX

STS Timing and CRUX are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

STS Timing ships an update every 5 months, CRUX every 3 months. The most recent releases landed on August 18, 2026 and August 12, 2026 respectively.
