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.

Elemental Weather is a cloud-based service and mobile application providing comprehensive weather data, including current conditions, extended forecasts, and historical weather data for web and mobile applications supporting active user communities. Available weather metrics include temperature, rainfall, wind speed (including gusts), snow, perceived temperature, humidity, and air pressure. Historical weather data is available at hourly and daily levels. Forecasts are available for hourly, daily, and 12-hour (day/night) periods. In addition to current, forecasted, and historical weather data, the Elemental Weather API provides hourly observations from the NOAA network of National Data Buoy Center (NDBC) buoys and Coastal Marine Automated Network (C-MAN) stations. All stations measure wind speed, direction, and gust; atmospheric pressure; and air temperature. In addition, all buoy stations, and some C- MAN stations, measure sea surface temperature and wave height and period. Conductivity and water current are measured at selected stations. Weather condition data is also available from offshore oil rigs and ships at sea participating in government data reporting programs. The Elemental Weather app also presents near real-time data provided by the US Geological Services (USGS) Groundwater and Streamflow Information Program. The program supports the collection and delivery of streamflow and water-level information from approximately 8,500 sites and water-level information from more than 1,700 additional sites. Our clients include marine fishery managers (at the federal, state, and local levels), nonprofit environmental and conservation agencies, universities, recreational anglers, outdoor enthusiasts.

Verdict

The call

The clearest difference is review sentiment: ARMAS at 100% against Elemental Weather's 0%. ARMAS also leads on rating (4.3 vs 1.0) and update cadence (every 2 months vs every 7 months). Elemental Weather's advantage is in-app purchases (none vs 3) and iOS requirement (12.0 vs 14.0). On price, ads and device support there is nothing between them.
