User reviews

開始APP時YouTube會停止

你好
收聽YouTube時開啟iFORA O2,YOUTUBE會自動停止播放,請問如何改善?

連線以及資料接收失敗

明明就有戴著,也確定電有超過50%但是…卻無睡眠資料。連線也要多次嘗試😓

APP真的很瞎

ㄧ直連不到
超難用

失望

看思思醫師推薦才買,結果APP超爛,常常連線不上,或者記錄丟失,都改過多少版本了還這麼不穩!要不是想支持台廠,其實可以直奔三星..
APP真正爛,所以不可能有意願訂閱去了解其他資訊

連線失敗

更新過後App一打開就會顯示連線失敗,整個軟體都不能使用,再麻煩儘速修正~~

另外app更新完後戒指前一天的睡眠記錄都消失了😮‍💨
還有最近戒指都偵測不到跑步的時長,常常顯示無資料😭
