自宅情報が記憶されない

何回登録しても自宅情報聞かれるんだけど。
どこに記憶するの？

地震直後に開いたらエラーで情報が取れない

震度5クラスの揺れ直後にサーバー落ちる防災アプリはいらない。何年も使ってきましたが、サブスク解約することにしました。情報の質量ともに東京都の防災アプリの方がずっといい。さよなら。

設定の意味なし

現在地の震度設定して音も設定してるのに、震度1で聞きたくない通知音で毎回鳴る。勘弁してほしい。

8/10 0：48、滋賀県北部で起こった地震について

地震が起こった後に通知されるとかもう終わってる。
巨大地震の時にもそんなこと起こしてたら知らん間に命落とすで。ほんまに良くなかった

防災別に軽く行動管理しておくひとつに。

長くなりがちなシュミレーション別でも一方向にサクサク読めるのがよい。把握しやすい。

防災系で上位にヒットするものは、通知のほか地図と災害の関係がメインで解説が何かと押しやられがちだが、これは備える点との両用といった感。

あと災害別のアイコンとアニメーションが可愛い。

防災シュミレーション用にインストールしてみた。
