### 5/5 — あざっす！

*2025-10-07*

いつもお世話になってます！生活習慣の改善に役立ってます。

要望なのですが、カレンダー機能で翌日以降のタスクを前もって設定できると便利かなと思います

### 1/5 — お勧めしません！

*2024-05-18*

このアプリをインストールして禁酒をしようとすると、課金するまで他のアプリが使えなくなりました
この制限を解除するにはTODOをこなさいと使用制限が解除されないと書かれていましたが、TODOを追加するにも月500円の課金を促されます
結局アンインストールしないとスマホが使えなくなる、最悪の体験でした

### 5/5 — 禁欲が生活を変えた！

*2023-05-31*

このアプリを使うと欲望を抑制する習慣が身につきました！
今後も使っていきたいと思います。

### 1/5 — 1週間試してみたが

*2023-05-13*

顔写真登録できる
TODOリストもよい
だがこれで500円課金するほどか？という印象
無料だったら使うかも。

### 3/5 — 最強とは言い難い

*2023-04-21*

●スタイリッシュなデザインは他の禁欲アプリと比較すると群を抜いて素晴らしい。

●背景画像を設定してもその大部分が禁欲の目標や日数、またtodoによって見えなくなる。

●todoリストがあるのは良い。

●文章で設定した目標を後から変更できないのは歯がゆい。誤字脱字などがある時に直せないのは他アプリと比べて若干劣る。

●顔写真システムは意外と面白い。

●オフライン時に使用できないのが多少不便。

●上記の内、背景画像設定やtodoリストの設定、また顔写真システムは課金しなければ使えない。要するに課金しなければシステムの大部分は使えない。

●オフラインだと使えない点や目標が後から変更できない不便さも踏まえて、私の場合は1ヶ月500円継続して課金しようと思えなかった。

**Developer response:** フィードバックありがとうございます！
最強になれるようアップデートを重ねていきたいと思います！

### 5/5 — これで禁酒続いてます！

*2023-04-18*

禁酒80日突破しました！

SNSでオビワンズの人たちも頑張ってるので自分も頑張れます！

**Developer response:** ありがとうございます！
今後ともオビワンズを盛り上げていきましょう！

■A comment from the developer
Hi, Obiwans. How are you all doing?

I've surpassed 180 days of sobriety. 
Just between us, I've also been No Fap for same duration as well.

In this world, there are only two kinds of people: those who follow through and those who don't. 
I believe that about 90% of people fall into the latter category.

Humans are vulnerable beings. 
Even when we know that indulging in immediate pleasures will lead to long-term losses, we tend to choose the immediate gratification. 
Only those who can follow through can reap long-term rewards.

OB-1 is precisely the tool to help us discipline ourselves and attain those long-term rewards. 
Make good use of OB-1 and become a person on the side that succeeds.

Or will you end your life as someone who couldn't follow through?

Life is fleeting, and when you die, you don't want to have regrets. 
Aim for a life without regrets.

### 1.3.1 — 2023-07-07

Hello everyone at ObiWans, long time no see. This is KBOY, the developer.

Have you noticed what has changed in this update? There are two points of change.

One is an update developed by KBOY. The other is an update by Professor Tooru. It may only be noticeable to those who are abstaining from drinking or indulgence. Did you notice?

By the way, ObiWan can actually be used to add other types of restrictions, not just abstinence from drinking or indulgence. For example, those who eat too many sweets can set a "sweets ban", and those who use their smartphones too much can set a "smartphone ban". In fact, we are preparing to implement a feature related to the "smartphone ban", and we plan to work on it all at once when we do a sauna work with Professor Tooru in July.

As some developers may already know, the iPhone has a feature called Screen Time, and its API can be used by third parties. There are not many examples of this being called with Flutter, but we'd like to give it a try. If possible, it would be great if it could be made into a package...!
