## What is Triad AI Journal?

A diary app that helps you notice how your "good days" change

Just pick one of three choices each day.
Choosing between "Good / Okay / Bad" takes three seconds — and over time, it reveals how your own definition of a "good day" is quietly changing.

■ Nothing to write. That's why it lasts.
Three Choice Diary is a diary for people who could never keep one. There's nothing to think up, so even on busy days or low days, you're done in three seconds. Miss a day? No guilt at all.

■ Made for you if…
・Your diaries always fizzle out after a few days
・You want to understand your own feelings and values better
・Your days feel like they're just passing by
・You want a calm, ad-free app

■ Four steps that change you

STEP 1 | Keep recording
Three seconds, three choices. Simple enough that you won't give up — first, we help you keep going.

STEP 2 | Know yourself
Grounded in psychology (Schwartz's theory of values, the VIA character strengths, and the Big Five), AI analyzes your records to reveal your values, strengths, and personality — including sides of yourself you never noticed.

STEP 3 | Find insight
A gentle daily report puts the day's emotions and context into words. Weekly and monthly reports — plus special reports — mean your diary never ends at "just written down."

STEP 4 | Notice your changing yardstick
As your records add up, you'll see how your standard for a "good day" has shifted over time. You'll notice the gap between assumptions and true feelings, and learn to cherish what a "good day" means to you now.

■ Psychology, woven into every day
Supervised by a Doctor of Psychology, built on the mission of turning academic insight into tools you can use every day.

"The 'calendar circle-and-cross method' I wrote about in my book The Mechanism of Happiness has evolved into this."
— Prof. Takashi Maeno (Dean, Faculty of Well-being Studies, Musashino University)

"Turning psychological insight into a tool for everyday life is an ambitious undertaking."
— Prof. Shigehiro Oishi (Professor of Psychology, University of Chicago)

■ Use it with peace of mind
・No ads, ever
・Calm, gentle design
・AI comments that stay faithful and precise to your diary

Try it free for one week.
Your change begins the moment you choose today's "good day."

### 3/5 — どうしたら購入できる？

*2026-05-10*

無料期間に使ってみて気に入りました。Appleアカウントと連携してプレミアムプランを購入しようとすると、「このアカウントは既に使用されています」とメッセージが出て次に進めません。どうしたら？？

**Developer response:** 追伸
アカウントの紐付けに失敗する不具合を修正しました。アプリをアップデートして再度お試しいただけると幸いです


ご連絡ありがとうございます。アカウントの紐付けに不具合があるようです。こちらでも確認できました。早急に対応して修正版をリリースします。恐れ入りますが、日記を継続しつつ、修正版をお待ちいただけると幸いです。また、allgood.saeki@gmail.comでサポートしていますのでより詳細なサポートが必要であればぜひメールください。よろしくお願いいたします。

### 5/5 — アドバイスが的確

*2025-06-30*

自分が書いた日記に忠実にかつ的確にコメントをくれるので、続けたくなる。しかも、そのコメントは優しい内容で、厳しいアドバイスもなく、ありのままをさらけ出しやすい。
できれば、毎日の日記に対してレポートが来るようになればモチベーションが上がるかも思います。

**Developer response:** レビューありがとうございます。振り返りレポートは特に力を入れているところなので評価していただけて嬉しいです。ぜひ今度はレポートにコメントもしてみてください。例えば「私の日記に合う音楽を提案して！」のような追加の要望にも答えるはずです。毎日のレポートについてはAIのコスト的に現状対応していないのですがユーザーの方のモチベーション継続はとても大事なので再検討してみます。レビューありがとうございました。

### 4/5 — とても良いのだが

*2025-05-16*

今日の日記を書き込んだあとに通信に時間がかかるのか、すぐにはアプリに反映されず、「あれっ保存したのに」としばしばなります。もっとも通信については、私のアイフォンに問題がありそうなので、このアプリの設定のせいかどうかは、ハッキリしません。

**Developer response:** アプリ改善につながる素晴らしい指摘ありがとうございます。すぐ反映されるように修正しました。ご指摘ありがとうございます。アプリにフィードバックフォームを用意してますので何かあればそちらもご利用ください。より迅速な対応ができます。

### 5/5 — もっと人気が出るべきアプリ

*2025-03-31*

•3択だけでもいい、取り留めなく書き殴ってもいい、その日の気分に合わせて使えるので、飽き性の私も続けられています！
•振り返りレポートは、週間、月間に加えて、スペシャルレポートがとどきます。先日はセルフケアレポートというものが届き、内容を読んでびっくり。悲しいことがあった週で、人にも話したくない内容だったのですが、その件に対する心に寄り添う内容のレポートが届いていました。自分の気持ちと改めて向き合う時間ができ、あたたかい気持ちになれました。普段のレポートも、内容が充実していて、毎週の楽しみであり、日記を書くモチベーションになっています！
•アプリ内の問い合わせから、振り返りレポートを印刷できるようにしてほしい、と送ったら、すぐにPDF出力できるアップデートが入り、私の他にも要望があったのかもしれませんが、運営の方の対応の速さにも驚きました！

**Developer response:** す〜☺︎さま
丁寧なレビューありがとうございます。振り返りレポート喜んでいただけて幸いです。このアプリをつくってよかったと思いました。また何かご要望があればアプリ内フォームからお知らせください。

### 5/5 — こういうのが欲しかった

*2025-01-20*

飽き性でも続けられる日記かと思います。

眠い時や面倒な時は3択の気分だけ選べば良いのもgood
個人的に1番気に入っているポイントはしっかりと丁寧に作られているUI周りです。
広告はなく、ユーザーフレンドリーです。
正直最近のアプリは落ち着きがなく辟易していたので落ち着きのある雰囲気がとても気に入っています。

AIの感想的なものも貰えますが一人暮らしの寂しさを紛らわせるのには調度良いかも…

**Developer response:** アエエ様

レビューありがとうございます。
気に入ったポイントなども書いていただきありがとうございます。
とても参考になりました！

落ち着きのある雰囲気が評価されているのは発見でした。
今後のアップデートでもその良さを損なわないように気をつけたいと思います。

今後も３択日記をどうぞよろしくお願いいたします！

### 5/5 — 簡単で良い

*2024-08-18*

日々の振り返りアプリを探していました！
3択で選べていい！
続けられそうでいい！

**Developer response:** ありがとうございます。引き続き３択日記をご利用ください！
