### 1/5 — 資料停留在4/7 不再更新

*2021-02-26, version 1.4*

若不更新 可以下架軟體嗎
誤導了多少人 明明空氣很差
沒心做就刪掉吧

### 1/5 — 資料居然停留在4/7 10:00，這會不會太扯！

*2021-02-05, version 1.4*

明明都可以感受到空氣很糟，上網至AQU查詢，也都是爆表的空汙，這會不會太糟了⋯⋯要不是真的覺得空氣很糟，要不是真的仔細去看日期，還真會被這APP騙了！

### 3/5 — 廣告方式可以改一下嗎？

*2017-02-14, version 1.4*

廣告多沒關係，但可以不要蓋住整個螢幕嗎？！

### 5/5 — 實用

*2016-03-28, version 1.4*

簡單明瞭又好用，有推播功能。好軟體值得鼓勵！

### 1/5 — 判定不準呢

*2015-12-16, version 1.4*

超過78應該是等級10了吧

### 1/5 — 爛，亂顯示

*2015-10-21, version 1.4*

pm2.5濃度32，顯示為高(等級9)是要嚇誰？看對照表明明才等級3，亂七八糟。
