# 気象天気図 vs 雷アラート

The clearest difference is ads: 雷アラート at none against 気象天気図's shown. 雷アラート also leads on iOS requirement (8.0 vs 17.0). 気象天気図's advantage is review sentiment (81% vs 47%) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

気象天気図 ships an update every 3 weeks, 雷アラート every 2 months. Both last shipped on November 1, 2026.
