### 2/5 — ？？？

*2025-07-03*

アップデートした途端に｢お気に入り｣が全部消えてしまった。それと､以前から思っていたのだが､｢情報｣で表示されるアメダスの位置がズレているのではないか。例えば友ヶ島などは海上を指した上に標高44mと出るのは､明らかにおかしいと思うが。

### 4/5 — いつのまにか

*2024-03-08*

昨年、概況、ランキング、お気に入りの過去データが表示されなくなりアンインストールしました。
今日、再インストールしたところ過去データが表示されるようになっていました。
ランキングの復活を望みます。

### 1/5 — 役に立たない

登録地点の現在状況と少し前はわかるがそれだけ。
マップに色々表示されると書いてあるが何も表示されない。

### 1/5 — もはや使えないアプリ

*2023-08-24*

ランキングは真っ白で何も表示されない。概況は日本地図が出るだけ。まったく機能しない。

### 3/5 — 過去データが更新されない

*2023-05-07*

いつも便利に使っておりましたが4月に入る頃から過去データが更新されなくなりました。

ご対応お願い致します。

### 1/5 — 役立たず

アプリ内の項目どれも使えない。中身が空っぽ。何やってんだ。

### 1/5 — 不具合多すぎ

*2022-11-01*

概況不具合です
何も表示されません

### 4/5 — 開発者の方の努力が感じられるアプリ！

*2022-09-25*

私はドローンが趣味で出かける前にこのアプリで風速が確認できるので、とても重宝しています。シンプルでとてもいいアプリです。
要望としては、過去の風速のグラフ化ができたら最高です！大変だと思いますが、これからのアップデートも期待しています！
