# Pressurisation vs HitDex

The clearest difference is update cadence: HitDex at every 2 weeks against Pressurisation's every 2 months. Pressurisation's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Pressurisation ships an update every 2 months, HitDex every 2 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
