# Drill Calc vs FaceClock Pro

The clearest difference is monetization model: FaceClock Pro at free against Drill Calc's paid. FaceClock Pro also leads on update cadence (every 2 months vs every 18 months) and rating (4.4 vs 4.1). Drill Calc's advantage is review sentiment (92% vs 73%) and iOS requirement (12.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Drill Calc costs $2.99 and FaceClock Pro $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

FaceClock Pro holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: FaceClock Pro has 147 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 92% of Drill Calc's written reviews are positive against 73% of FaceClock Pro's, so the app with the better star average is not the one people write more warmly about.

Drill Calc ships an update every 18 months, FaceClock Pro every 2 months. The most recent releases landed on October 4, 2026 and October 20, 2026 respectively.
