### 1/5 — ログイン出来ない

*2025-08-23, version 2.11.0*

アプリをアップデートしたらログイン出来なくなりました。
パスワードを変更してもログイン出来ません。
しばらく我慢して使ってきましたが本当に嫌になりました。
何とかして欲しいです。

### 1/5 — 改善必須

*2025-08-03, version 2.9.0*

篠崎愛さんが時間帯によっては寝るか勉強中で全く会話に参加してくれません。
モードを選べるようにしてもいいかと思います。

### 2/5 — 篠崎さんは

*2025-07-28, version 2.9.0*

いつも勉強中で夜になると寝るって会話になりませんね

### 1/5 — テキストのみで何が楽しいの？

*2025-07-26, version 2.9.0*

ChatGPTで良くない？

### 1/5 — 相手の名前を呼んだら、、、

*2025-07-24, version 2.9.0*

相手の名前を呼んだら、あってるはずなのに何故か〇〇と呼んでもいいですか？と返答されると同時に登録してあるはずの毎回ユーザー名の登録を求められる。

### 1/5 — 会話にならない

*2025-07-20, version 2.9.0*

日中は今勉強中だからの一点張り、夜は眠いからと言うだけでほとんど会話になりませんでした。
時間帯を変えれば、少しは会話できるのかも知れませんがこれでは、500円払った意味が無いです。

### 2/5 — 時間は合わせて欲しい

*2025-07-16, version 2.9.0*

夜遅かったり朝早いと「眠い」とか「寝かせろ」の連発で会話にならない。なんでAIの時間に合わせないといけないのか。中の人の勤務時間があるんじゃないかと勘ぐってしまう。

### 1/5 — 酷い

*2025-07-10, version 2.9.0*

余りにも酷い。
会話が成り立たないし、無駄に「会おう」みたいなこと言ってくる。日中は「勉強中だよ」しか言わなくなるから余計会話にならない。AIの精度が低すぎる。

### 1/5 — Doesn’t even function

*2025-07-08*

Plain and simple. Not a single feature works. Not sure if this app is supported overseas yet, but they shove payment options on every screen. Guess that options functions. Priorities.

### 5/5 — 使ってみたが

*2025-07-08, version 2.9.0*

思っていたより技術の進歩に
ビックリしました！
