### 3/5 — Tony

*2026-04-08, version 2.2*

5

### 2/5 — 5段階しか記憶されない

*2026-02-24*

明るさが100段階で数値化され調整できるが、保存は5刻みでしかできない（例:｢37｣で保存しても実際に保存されるのは｢40｣）のが残念。

### 2/5 — 何世代前のiOSまで対応してたのか

*2026-02-20*

iOS26.2の現在、このアプリで明るさ調整するとそのまま大元の明るさ設定にも反映されてしまいリセットされなくなる。
非常に使い勝手が良く愛用してたけど、更新する気がなさそうだし削除します。

### 4/5 — 操作性抜群

*2025-10-24*

操作が簡単でやりやすいと実感しておりますが、もう少し明るさ、輝度が明るくなれば最高です。

### 4/5 — いつもありがとうございます

*2025-05-22*

アプリを開いてしばらくは希望の明るさでいれるのですが…。

一端携帯電話がスリーブ状態になり、通知センター画面になると本来の（携帯電話の）

電池状態に戻ってしまうのは少し残念だな…。

ということでこの評価です。

運営さんごめんなさい…。だけど今後も
楽しく使用したいと思うので頑張って下さい。

### 2/5 — ウィジェットなんて無い

*2025-05-20*

App Storeのプレビューでは「100-21-AUTO」のようなウィジェットが置けると記載があるので期待しましたが、ウィジェットなんてありません。

### 3/5 — 便利だが、ロック解除すると戻る

*2025-05-01*

このアプリで調整したまま終了した場合、ロック解除して画面復帰すると、調整前に戻っている点が残念

### 3/5 — Dimmer

*2025-01-04, version 2.2*

It won’t stay on

### 4/5 — 毎日使ってる

*2024-10-20*

通勤時に日中は画面の明るさを最大にしないと暗くて見えない。
そんな時にこのアプリなら2タッチで明るさ調整できるので毎日使ってます。

### 5/5 — あると便利なアプリ

*2024-10-15*

iPhone16PROに変えてコントロールセンターを出すのに右上から下へスワイプしなければならないのがやり難くてクイックボタンにこのアプリを登録して明るさ調整が簡単にできるようになりました。

### 1/5 — Porn Adverts

*2026-07-25, version 2.2*

I want to use your app but you need to get rid of the porn advertizements.

### 1/5 — 使えない

*2026-06-26*

スマホ使うたびに設定が解除されてたら意味ねーんだよ

### 1/5 — Bad

*2026-03-10, version 2.2*

This app doesn’t darken your screen. 
It only changes the brightness you already have it set on

### 1/5 — DONT GET THIS APP

*2025-12-11, version 2.2*

it LITERALLY doesn’t do ANYTHING like what. what is the literal point of this app? if u want to adjust brightness then ADJUST THE BRIGHTNESS WHY DO U NEED A APP😭😭😭i thought this was a app for lower brightness bruh jus wasted my time like what ??? im going to sleep now a lil angry😭

### 1/5 — Flashbanged me

*2025-10-07, version 2.2*

Preset a made my eyes water

### 1/5 — Yeah no.

*2025-06-23, version 2.2*

I’m actually really disappointed I thought this would help my brightness to go way lower but it didn’t do that at all I downloaded this app originally bc the darkest option on my iPhone was way to bright for me that it burns my eyes at night, this did absolutely nothing to help with eye comfort.

### 1/5 — Doesn’t work

*2025-01-10, version 2.2*

Doesn’t work and tries to steal your data

### 1/5 — Useless

*2024-12-17, version 2.2*

There’s literally no point to this app. I simply wanted something that might dim my phone more than the standard brightness lets you on an iPhone, but this app literally just does nothing new. There is absolutely nothing being brought to the table with this app but it’s getting recommended everywhere I search for ‘darker screen brightness’. How do you mess up that bad and not only get away with it, but get monetized, and get recommended? It’s so infuriating that I want just one simple thing and the only option available is a piece of garbage like this. I’d rather expose my eyes to raw nuclear waste radiation than look at something as outright stupid as this. Like the first thing I see the moment I open the app; the exact frame I press on the icon; is a notification request and ads everywhere. I wish I could see the person who created this app, as is not the nature of how bad the app is; no, it is the fact of the matter that someone on this planet could do something so petty and shameless and get praised for it. If I thought the app was just bad, I would have deleted it and gone on my way, but to see how petty the creator had to be just for a few pennies burns into me. This “app” is no different from any of the other mobile apps and games out there. They only ever have money in mind and can’t even make a usable product. So much of the world is filled with useless fluff like this app just so they can trick people into watching ads. And to think too that a Google “AI overview” recommended this to me? The one time I trusted it since I could find no other answer? No words fit that anger. The hatred I have for this topic is beyond words. It is beyond a frown or yelling. My anger is calm and quiet, which speaks volumes greater than anything I can muster. This is pathetic. A simple little app to change your brightness and you can’t even get that right.

### 1/5 — Loses setting

*2024-10-14, version 2.2*

It lets you make the screen brighter but in moments that’s lost. Removing app.

### 5/5 — Trouble avoided!

*2025-12-24, version 2.2*

When my iPhone came up dark because I had the light low, I remembered where the Dimmer APP was on my black screen. I hit it, and turned the light up!
That saved the day!

### 5/5 — College

*2025-11-08, version 2.2*

College

### 5/5 — Amazing

*2025-10-27, version 2.2*

### 5/5 — Great app

*2025-08-05, version 2.2*

Best screen dimmer I’ve tried . Simple yet effective. I’m using it for free and no annoying ads. Just awesome!
Recommend to everyone.
Thank you for developing such a great app!

### 5/5 — Satisfied

*2025-06-29, version 2.2*

Good enough

### 5/5 — Excellent

*2025-03-08, version 2.2*

Simple job.  Simple app.  Well done.

### 5/5 — 暗くするやり方教えます。

*2025-02-11*

まず、このアプリではコントロールからできる明るさの限界までの調整しかできません。
ワンタッチでいつもの明るさに調整できるようになるのがこのアプリの強みです。

そして次にならどうすれば暗くできるのかです。
設定→アクセシビリティ→画面表示とテキストサイズ→ホワイトポイントを下げる(ここですきに調整)
これでコントロールから設定できる明るさより暗い画面に出来ます。
やってみてください。

### 5/5 — 明るさの数値化

*2024-12-28*

感覚頼りのスライダー表示のみの設定でなく、数値で表される曖昧さのない割り切り感を求めていましたので満足です。
