InterSpec assists in analyzing spectral nuclear radiation data, using a peak-based methodology. Common uses include identifying nuclides present, determining source activity, shielding amounts, source age, or other nuclear reactions present. InterSpec also provides a number of other tools useful for analyzing radiation data including spectral file format converting, dose rate calculations, interactive nuclide decay and reference information, gamma cross section calculations and references, and more. InterSpec can open data files from most common spectral radiation detectors (e.g., most NaI, HPGe, LaBr, CLYC, CsI, etc. based systems) and assist in their analysis.
RDS
This utility app connects to a radiation survey meter, displaying real-time data and allowing parameter adjustments. It also integrates with supervision services for enhanced monitoring.
- Connect to RDS-32 survey meter
- Display real-time device data
- Edit setpoints and parameters
- Connect to RadResponder
- Connect to Spirview Mobile

Verdict
The clearest difference is rating: RDS at 5.0 against InterSpec Radiation Analysis's 4.3. RDS also leads on update cadence (every 3 months vs every 11 months). InterSpec Radiation Analysis's advantage is ratings volume (12 vs 1) and iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.
