# PSA vs A/C Pro

The clearest difference is rating: PSA at 4.8 against A/C Pro's 2.1. PSA also leads on review sentiment (57% vs 27%) and update cadence (every 4 days vs every 4 months). A/C Pro's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, 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.

PSA holds the better App Store score, 4.8 against 2.1. That said, the two scores are not equally well evidenced: PSA has 63K ratings behind it against 303, so its average is the more settled of the two. Written reviews point the same way: 57% of PSA's written reviews are positive against 27% of A/C Pro's.

PSA ships an update every 4 days, A/C Pro every 4 months. The most recent releases landed on November 9, 2026 and November 7, 2026 respectively.
