# InterSpec Radiation Analysis vs SmartPLL

The clearest difference is rating: SmartPLL at 5.0 against InterSpec Radiation Analysis's 4.2. InterSpec Radiation Analysis's advantage is ratings volume (10 vs 1) and iOS requirement (11.0 vs 13.1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

SmartPLL holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: InterSpec Radiation Analysis has 10 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 11 months. The most recent releases landed on October 17, 2026 and October 5, 2026 respectively.
