## What is Will?

### 5/5 — ありがとう

*2025-11-27*

諸事情で好きですって言えない相手がいるから、最期に好きでしたって残しておけるじゃんって思って入れました。
俺が死んだ時見てもらえるかは別として吐き出せるのはいい事よな

### 1/5 — メッセージの書き方がわからない

*2023-08-27*

見て欲しい相手の名前は書けるけど肝心のメッセージが書けないんですがどうやるの、、、

### 5/5 — スッキリした！

*2023-07-19*

最初，自分が死ぬわけではないけれど，
もしも自分が死ぬとしたら。と思って描いてみました。
本人に伝えたい事を思う存分書きました。
書き終えた時、とってもスッキリしました！
今後も使わせていただきます！
何か思ったり，悩んだり、また伝えたいことがあったら
ここに書いてみようともいます！
こんなに素敵なアプリを作ってくれてありがとうございます！
めっちゃおすすめです！

### 5/5 — あ

*2023-07-10*

死ぬ勇気はないですが、どうしようもなく死にたくなる時があります。そんな時に遺書を書いていつでも死んでいいんだっていう安心感が持てます。実際に勇気が出た時は見返してみます。

### 5/5 — 死にたい時にリアルに考えられる。

*2022-11-06*

私は総合失調症ですが死にたいと思った時に自分が死んだら…をちゃんと考えられることが出来るので重宝しています。

### 4/5 — 写真

*2022-10-01*

遺影を残したいです

### 4/5 — ちょこちょこ改善してほしい

*2022-09-11*

全体的に良かったんですけどももう少し細かく言うと広告を無くして欲しい事とタイトルのとこに絶対｢～～へ｣ってつくのを無くしてほしいです
それ以外は完璧です

### 5/5 — Good

*2022-08-23*

使ってみて良かったです。
本音では言えないことをかけました。これで心おきなく、病気と向き合えます。

### 1/5 — パス

*2021-03-21*

パスコード設定できない

### 3/5 — 「〜へ」がいらない

*2021-02-02*

遺書なので誰かに向けて書くのですが、例えばお葬式の事や飼い犬の世話などやってほしい事をリストにしたい場合もあるので、その際「〜へ」が邪魔になります。
（「◯◯について　へ 」みたいになっちゃうので…）
できたら外してほしいです。

あと贅沢かもしれませんがやっぱり広告が邪魔、というか雰囲気壊します。
