## What is MeroTalk | LINE Analysis?

The LINE compatibility diagnosis & chat analysis app everyone's using — "MeroTalk"

Simply import your LINE chat history,
and your relationship will be classified into one of 16 types.

The other person will never find out.
Chat content is analyzed entirely on your device without going through the internet.
(Internet connection is required only when using AI features)

"What kind of distance does this ongoing relationship really have?"
"Are our feelings actually out of balance...?"
—Those relationships that are hard to put into words become visible through data.

### 3/5 — チャットチケットについて

*2026-09-03*

無料プランですが、チャットチケットを持っているのにチャットは1日5回まで となります。チャットチケットを使うようなボタンも無いし、これは一体何なのかどう使うのでしょうか

### 3/5 — 自分の容量がないだけかな？

*2026-08-30*

今日初めて使ったんですけど、相談で押して行って「このままでいいか不安」を押すと画面が強制終了させられるんですけど毎回。それと相手との相性確かめたところのサマリを押すとそれも強制終了させられます。直らないですかね？

### 3/5 — 悔しい

*2026-08-27*

凄く使いやすく色々な事が分かって面白いし助かります。

ですが、"この人と自由にチャット"の機能を使おうとするとどうしてもアプリが落ちてしまいます。

解決策はありますか？😭

### 1/5 — 使えない

*2026-07-28*

バージョンアップしてから、Aiの相談が回数がどうのってなり、Premiere＋に入ってるにどうゆう事ですか？チャットもAPIエラーってなるんですけど。前にも文字とか途切れてたりして、不便でした。問い合わせが、全然使えないし困ってます

### 1/5 — 付き合いが浅い人向け

*2026-06-02*

パートナーとのトークを分析しようとしたが、トークの履歴件数が多すぎるせいか何度やっても解析中と5分ほど表示された後にアプリが落ちてしまうので、諦めました。使ってみたかったので残念です。トーク履歴件数が少ない方向けなのかな？

### 1/5 — エラーになってできない

*2026-05-16*

メッセージが見つかりませんってなって全然できない。3人くらい個人チャット試したけどダメ。何が原因ですか？改善してほしいです

### 2/5 — 。

*2026-05-16*

めっちゃいいんだけど運営さん本当に見て欲しいです。ブロック機能ください！！！！不快なコメントは削除できるけど、ブロックもさせてください！！！、、お願いします😭

### 2/5 — おもすぎる

*2026-03-28*

相談とかできるしいいなーって思ってPremiereのほうの課金したけど、何回か話すと画面が固まって強制終了しちゃう。長い文章打っても消えちゃうからマジで萎える。あとたまに、何語か分からない言語が会話にはさまれる。バグなのかな？

**Developer response:** お世話になっております。めろとーく開発チームでございます。
この度はアプリの動作不安定によりご不便をおかけいたしましたこと、心よりお詫び申し上げます。画面のフリーズ・強制終了・文章の消失・言語認識の不具合につきましては、最新バージョン（2.1）にて修正対応を完了いたしました。お手数をおかけいたしますが、アップデートのうえご確認いただけますと幸いです。今後ともよろしくお願い申し上げます。

### 4/5 — めろとーくLINE

*2026-03-27*

彼氏とメロトーク診断しました！！
めちゃくちゃよかったです！
でも課金のところは見えなくてちょっとかなしいなって思います。
彼氏と診断して彼氏に送ってみたら｢俺からもっと愛情表現するね｣って言ってくれました！
倦怠期気味で心配だったけど安心しました！

**Developer response:** お世話になっております。めろとーく開発チームでございます。
この度は温かいご感想をいただき、誠にありがとうございます！彼氏様との診断でお役に立てたとのこと、開発チーム一同とても嬉しく思います。課金周りのご不満につきましては真摯に受け止め、引き続きより使いやすいサービスとなるよう改善に努めてまいります。今後ともどうぞよろしくお願い申し上げます。

### 4/5 — 仕方ないけど

*2026-03-26*

基本的には色々な面から見れて面白いアプリだと思う
だけど、やっぱり収益のための制度があるのが非課金の我々にとっては少し痛手だが、1年で5000円でのアップグレードはかなり妥当以上だと思った
このアプリは無料でも十分楽しめる要素がかなり多くAIへの相談もできるためおすすめだ

**Developer response:** お世話になっております。めろとーく開発チームでございます。
この度は温かいご感想とともに、率直なご意見をいただき誠にありがとうございます。無料でも十分楽しめるとおっしゃっていただけたこと、大変励みになります。課金制度についてのご意見は真摯に受け止め、より多くの方に満足いただけるサービスづくりに努めてまいります。今後ともよろしくお願い申し上げます。
