The Automated Radiation Measurements for Aerospace Safety (ARMAS) program has been developed with NASA funding. It provides accurate, real-time radiation monitoring along with radiation and space weather awareness for the global airspace up to 100 km altitude. The ARMAS app is part of this program and does two tasks: - it pairs with and controls the 7th generation ARMAS Flight Module (FM7) and the 12th generation ARMAS Flight Module (FM12) radiation detector (purchased separately) to provide the highest quality, real-time dose and dose rates in aircraft and suborbital vehicles. It is sensitive to radiation from all sources including heavy ions, alphas, protons, neutrons, electrons, and gamma-rays. - it provides radiation awareness by hosting real-time space weather data coming from dozens of ground- and space-based systems that report all the information relevant to radiation processes without requiring a purchase of the FM7 or FM12. ARMAS is the 'gold-standard' in real-time radiation monitoring and awareness used by professional pilots, business travelers, and commercial space tourists. The ARMAS program is developed and operated by Space Environment Technologies, which specializes in space weather as an official NOAA "Weather Ready Nation" Ambassador.

Verdict
Storm Radar and ARMAS both sit at 4.5 stars, but that hides the real split: 100% of ARMAS's written reviews are positive against 65% of Storm Radar's. ARMAS also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.2). Storm Radar's advantage is ratings volume (137K vs 6) and update cadence (every 2 weeks vs every 2 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Storm Radar sells 7 in-app purchases, starting at $0.99 per month and ARMAS sells 3 in-app purchases, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.
Storm Radar holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Storm Radar has 137K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 65% of Storm Radar's written reviews are positive against 100% of ARMAS's, so the app with the better star average is not the one people write more warmly about.
Storm Radar ships an update every 2 weeks, ARMAS every 2 months. The most recent releases landed on November 7, 2026 and November 2, 2026 respectively.
