## What is White Balance Meter AI?

KEV is the #1 White Balance app.
KEV app turns your iPhone or iPad into a professional and easy-to-use light meter. Using KEV app is as easy as pie, no sensor required, the in-built camera already got you covered. 

Minimalist KEV uses AI to analyze live previews and provide accurate white balance data in Kelvin, making it a valuable tool for photographers and videographers.

Trying to get the perfect White Balance on your DSLR can be annoying. KEV helps you by letting you know what the White Balance should be. You can measure the colour temperature of a light source in Kelvin without having to spend hundreds of dollars on professional devices.

We calibrated KEV using Sekonic C-700R-U SpectroMaster Colour Meter, and we guarantee from fair to almost 100% accuracy. Just open the KEV app and point the camera on surface or scene.
 
The white balance is a correction of color rendition to make the picture from the camera sensor as similar to the perception by human eyes as possible.

Functions and Capabilities:
• Gets you Color Temperature in Kelvin in real-time.
• Ability to compensate and calculate the white balance readings.
• Capture a snapshot with color temperature reading and location.
• Ability to manually focus on the scene and objects.
• Minimal yet integral point and shoot capability.
• A go-to spectrometer for photographers, videographers, cinematographers, gaffers, drones and action cameras.
• Save time in post-processing.
• Mount your iPhone using hot-shoe over the camera or on a tripod stand and get colour temperature data on the KEV Watch app.
• Zoom in to get colour temperature data of a close-range.
• Balance Color Temperature of the Ambient Light and Your Light Source.

Override the Auto-White Balance and choose settings yourself.

### 5/5 — 色调问题

*2026-05-03*

作者你好，白平衡色温这些还算比较准确，至少比佳能的自动氛围和自动白色都相对中性舒服。 但是这个色调该怎么调整？相机都是白平衡偏移，没有 lr 那种数值。望解惑，感谢！

### 1/5 — Scammed

*2025-11-17, version 6.5.2*

Rubbish. What’s the point of taking photos when there’s the apps writing all over it?! Rendering them useless. Wish I hadn’t wasted my money.

### 1/5 — 黑屏

*2025-07-10*

换手机后就没再打开过，今天打开上纯黑的，摄像头权限开启了但是没用

**Developer response:** 嗨，感谢您下载 KEV 应用。建议您重新安装一次。黑屏现象并不正常，可能是权限设置的问题所导致。
祝好，
Satnam S.

### 5/5 — Awesome!

*2025-03-16, version 6.5*

Works perfectly. Just tested in my kitchen, matched the white balance perfectly. Must have for photographers!

### 5/5 — Works well

*2025-02-19*

Simple and reliable

**Developer response:** Hey Matias, thanks for the review. We are glad you like it. Thank you, Satnam S.

### 4/5 — 見事な測定

*2024-12-19*

撮影状況で刻々と変わる色温度に悩まされていましたが、このアプリで簡単に設定出来て時間短縮化されています。
画面内に表示される色合いとは「色かぶり」の補正値です。仮に+10.0と表示された場合にはマゼンダへ1.0補正すれば良い事になります。

問題はクリップオンのストロボを使用した時の補正値が計測されないのは残念です。

**Developer response:** Hey スナフキンちゃん, thanks for the review. We are glad you like it. Thank you, Satnam S.

### 1/5 — Doesn’t work

*2024-10-13, version 6.4.6*

Presumably because your reading this you want to “measure” colour temperature….this app doesn’t do this it guesses based on what is in the scene. You can do this yourself.

### 1/5 — Lacks Functionality

*2024-09-20*

No green/magenta tint adjustment reading in 2024. Lacks the ability to select a specific spot in the frame to get a measurement, like a white balance card that that’s to far away to fill your frame. Waste of money.

### 2/5 — Beginner here!

*2024-06-25*

I purchased the app about a year ago but only recently begin testing it out. So far it seems relatively accurate based on my findings using the xrite color checker. I do however hope they add a green/magenta reading as well to fine tune this using LED with tint sliders.

**Developer response:** Hey sykesboy4, thanks for your review! The feature you requested was added to the app some time ago. We'd love for you to check it out again.

Thanks,
Satnam S.

### 5/5 — How to set Chinese language

*2024-06-05*

This app is very useful and brief,but can you set a option for setting languages?

**Developer response:** Hey 请尽快改善卡顿, thanks for the review. We are glad you like our app.Here are the steps to set language:

1. Make sure you have a secondary language on your iPhone (Settings > Language & Region > "Add Language"). You don't have to set this new Secondary Language as the Primary.

2. Go to iPhone Settings > 'KEV WB' > Preferred Language. The first step mentioned above enables the 'Preferred Language' option.If you encounter and further issues, please don't hesitate to reach out to us by sending a message at 29satnam@gmail.com. We are here to help! Best regards,Satnam S.
