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.

Updated review: 5 stars

I had very little faith this would work. But I gave it a shot, pointed my camera at the white balance card, I was able to get the correct white balance every time. This app is definitely a life saver. I’m saving a lot of time in post processing. Very trustworthy, professional and accurate. I highly recommend this app. Thanks to the developer.

Not accurate in wide ranges

Long story short is not really accurate it wider ranges. If I come close to a source reflecting light it’s dead on but if I’m checking a scene, it’s off by like +2600 kelvins. Almost like the app is evaluative it on spot lol.

Developer suggestion: you should update with a simple option for us to calibrate the readings by adding a +/- kelvin box we can add +/- numbers. So if your app is reading 5000, Ican have a calibration number of -1500 so it shows me EXACT. I found its off in wider ranges here about 2600 and I compensate the calculation for my cameras white balance and it’s dead on after that.

Update: The new update is out with the requested feature. We hope you will come back to try the new updated app. ♥️

Worth it, even for one photo

I bought this for one particular problematic photo, in which I was shooting a multisource lighting condition, low light with a complex set of materials in the image

Kev gave me a kelvin number, I dialed it into my image editor, and the resulting image was exactly what I wanted

So nice 😊
