### 5/5 — Exactly what I needed AND FREE!!!

*2024-02-12*

I was desperate to find a candle light and THIS IS THE ONE! I can close my eyes and still see the flickering light and it’s JUST like a candle. And free?! Thank you SO MUCH for making this. What a legend. 100% recommend

### 5/5 — Great app!

*2023-09-11*

Make it so it can be used over 3rd party applications. If i exit the app the flickering screen disappears.

### 5/5 — 雰囲気でる

*2022-06-02, version 1.1.0*

さいしょえ？なにこれっておもったけど壁沿いにおいたらいい感じに雰囲気でる
電池も配線もいらないのがいい

### 5/5 — 素晴らしい！

*2020-05-10, version 1.1.0*

LEDランタンを検討していたところ、このアプリに出会えました。十分実用的です。
アプリ内に紙ランタンのつくりかたも掲載されていますし、シンプルに間接照明にしても良いです。
スマホで音楽をかけながら揺らぐ火を楽しむのが毎晩の楽しみになりました。

### 5/5 — Nice app

*2020-02-20*

A nice little handy app when you get the settings just right. Really does help to creat an authentic flickering candle glow in the room especially when you have the phone positioned correctly to bounce the light of walls and calling.

I find that the orange colour, full screen with flickering adjusted and with sleep timer set to desired length works best for me.

Be careful though, because someone took advantage of the fact that my iPhones remains effectively unlocked and they went through my phone’s data. Probably not the fault of the app, but more a vulnerability with iOS.

### 5/5 — Awesome light

*2020-01-13*

This is one of the only lights of its kind that I could find. It fills up the screen full screen (you can tap to remove ads). It looks like a flame in a dark room and does different colors.

### 5/5 — Works great!

*2017-09-18*

It's very bright, and has a lot of features that I wouldn't expect in a free app for this. You can change the color and pattern of the flickering, set a timer, and so on. Thank you for making this available.

It looks a little too bright and unnatural with the screen just exposed, so I would recommend taking the advice from the in app video. Create a paper lantern for it or place it underneath something similarly diffusing, especially if you were thinking about using this as a night light. But once you set that up, it's totally awesome!

### 4/5 — 結構いい！

*2017-06-04, version 1.0.1*

明るさの調節機能とちらつきや揺らぎがもっとゆっくりになると満点です(*´ω`*)
