### 1/5 — ごみ？

*2026-05-23, version 3.11.37*

と思ったら間違いなかった。管理者側の都合にはいいかもしれないけど、利用者の都合は知ったことないゴミ

### 1/5 — あり得ないくらい適当なアプリ

*2026-04-22, version 3.11.37*

登録ができないので電話かけたが有料電話だし、ほんとに分かりづらい
不親切極まりないアプリ

### 1/5 — 使いにくい

*2026-03-27, version 3.11.37*

ひたすら使いにくい　年1回ほど電池交換しないと部屋の鍵が開かなくなるよう

### 1/5 — ゴミ

*2025-12-01, version 3.11.37*

ガチでゴミ

### 1/5 — ややこしい

*2025-09-07, version 3.11.37*

設定にかなり手こずった。紙でもらったやつもわかりにくくiPhoneと Androidで全然違うのに説明した奴も説明できていなかった。電池式だし電池無くなったら家入れないんじゃないかと怖い。

### 1/5 — ややこしい

*2023-10-03, version 3.11.37*

OPELOはややこしい

### 1/5 — ライン解錠通知

*2023-02-26, version 3.11.37*

LINEの解錠通知が届くのはAndroidのみ
iPhoneで解錠しても、iPhoneは非対応なため
LINEの解錠通知は届かない。

iPhoneの人はアプリをインストールする意味ない。

### 1/5 — マニュアルアプリ？

*2023-02-26, version 3.11.37*

iPhoneでは自動通知もなく、アプリで鍵を開けることもできないとオペレーターの方に言われたので、入れる必要のないアプリ。ただのマニュアル確認アプリ

### 1/5 — ゴミ

*2022-12-25, version 3.11.37*

QRコードも読み取れねぇ欠陥アプリ
