## What is Diety?

Choose how you share your weight.

Diety is a shared weight-tracking app that helps you stay consistent with friends, family, or your partner.

Just enter your weight each day, and Diety automatically turns your progress into graphs.
In each room, you can choose to share your actual weight or only the change from your starting weight.

“I feel uncomfortable showing my actual weight.”
“But I can’t keep going alone.”
“I want to stay motivated with someone.”

Diety is for people who want to keep going together, without feeling pressured.

Choose what you share

Each room lets you choose how weight is shared.

- Share only how many kg you have gained or lost since the start
- Share your actual weight

Keep going at a distance that feels right for your group.

Continue together in invite-only rooms

Invite friends, family, your partner, coworkers, or anyone you want to work toward your goals with.

Even if you have had trouble tracking on your own, it becomes easier when someone is there to follow your progress with you.

Simple daily tracking

Enter your weight once a day.
You can also record your body fat percentage, add a stamp, and leave a short message.

“I worked out.”
“I went out for drinks.”
“I did a little better today.”

Diety helps you record the mood and moments behind the numbers, not just the numbers themselves.

See your changes in graphs

Check changes in your weight and body fat percentage with easy-to-read graphs.

Switch between 1 month, 3 months, and all time to see both short-term and long-term changes clearly.

In rooms, you can also see each member’s progress, so everyone’s effort comes through naturally.

Share records with your room

When you record your weight, a record message appears in the room.

Add a stamp or short note, and your weight log becomes a small diet diary.

On good days and difficult days, you can gently support each other as a group.

Reminders so you do not forget

Set a reminder at your chosen time so you do not forget today’s record.

Diety keeps the support simple and focused on what you need to keep going every day.

Recommended for people who:

- Have trouble continuing a diet alone
- Want to manage weight together with friends or family
- Feel uncomfortable sharing their actual weight
- Want to share only weight changes
- Want to manage health as a couple or with a partner
- Want to see weight and body fat changes in graphs
- Want to keep going with stamps and messages
- Want to make daily weight tracking a habit

A diet app built to support, not monitor.
Start tracking your weight with Diety, without carrying it all alone.

以前記録が曖昧とレビューしたのですが訂正します。お返事があり私の設定が間違ってたようで、そこは詳しく説明を詳しく載せて欲しかったです。ただ、このアプリは本当に素晴らしい👏他にはこんなアプリ探してもみつかりません

### 3/5 — アカウント復元できず

*2025-06-28*

アドレス登録してなかったようで、スマホ変更とともにデータを失いました..。他同様、Apple側で保存しておいてほしかった..。

### 4/5 — お願い

*2025-06-08*

現在15人の制限にしているのですが、20人に変更したいです。人数制限を20人にし、更新ボタンをタップしても20人にはならず、15人のままになってしまいます。自分だけなのかもしれませんが、もしバグでしたら修正していただけると嬉しいです。

**Developer response:** レビューありがとうございます！

こちらで同じ現象を確認できなかったため、よければアプリ内の「マイページ > お問い合わせ」からご連絡いただけますでしょうか？
詳しく調査するのに、とても助かります🙇‍♂️

ご協力よろしくお願いします！

### 4/5 — 継続に役立ってます

*2025-05-08*

やる気がない日も誰かと一緒にやっていると思うと最低限計測だけは頑張れたりするので、とても役立っていますが、複数のグループがあっても、コメントが統一されてしまうので、グループごとでコメントできると尚良いと思います

**Developer response:** 貴重なご意見とレビューをありがとうございます！☺️

今後の機能開発の参考にさせていただきます！

今後ともご愛用いただければ幸いです！

友人と一緒に目標立てて頑張れるところがいいですが、
ヘルスケアとの共有ができないので、食事管理のアプリとの併用が難しいです。
共有できるようになりませんでしょうか？

**Developer response:** レビューありがとうございます！

ヘルスケアとの共有についてはご不便おかけしております🙇‍♂️

今後の開発で、ヘルスケアと共有もできるように頑張っていきますので、引き続き応援よろしくお願いします！
