# InterSpec Radiation Analysis vs SatRadio

The clearest difference is rating: SatRadio at 5.0 against InterSpec Radiation Analysis's 4.2. InterSpec Radiation Analysis's advantage is ratings volume (10 vs 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.

SatRadio 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.

InterSpec Radiation Analysis ships an update every 11 months, SatRadio every 10 months. The most recent releases landed on September 13, 2026 and June 3, 2026 respectively.
