The scale ranges from Level 1 to Level 7, with higher levels representing events of greater significance. ABOUT THE DATA Some incidents occurred before INES was introduced or do not have a confirmed official rating. In these cases, the app may show an estimated or equivalent level based on publicly available information. Historical sources may differ in their reporting of dates, release estimates, exposure levels, and event sequences. Where relevant, the app identifies these uncertainties. DISCLAIMER INES Maps is an independent educational reference app. It is not affiliated with or endorsed by the IAEA, any government agency, regulatory authority, or nuclear facility operator. This app does not provide emergency alerts, real-time radiation monitoring, medical advice, or official safety instructions. For emergencies and current safety information, always follow announcements from the appropriate authorities.

Verdict

The call

The clearest difference is ads: X at none against INES Maps's shown. X also leads on iOS requirement (12.0 vs 17.6). INES Maps's advantage is update cadence (every 6 weeks vs every 6 months). On price, in-app purchases and device support there is nothing between them.
