Verdict
The clearest difference is rating: Ajax PRO at 4.7 against Napco Prima's 4.2. Ajax PRO also leads on update cadence (fortnightly vs every 2 months). Napco Prima's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Ajax PRO holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 15 and 12 respectively. Written reviews complicate that: 72% of Ajax PRO's written reviews are positive against 75% of Napco Prima's, so the app with the better star average is not the one people write more warmly about.
Ajax PRO ships an update fortnightly, Napco Prima every 2 months. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
