## What is TruHu Monitor Calibrator?

TruHu brings accurate colors to your monitors with a simple app that measures your monitors’ colorimetric values using your phone’s camera.

We use our proprietary algorithm to analyze your computer screens and determine the best ICC profile to achieve accurate colors.

With TruHu, you can calibrate your screen in just 1 minute. Simply download the iOS app, the desktop app (linked in-app or on TruHu.app), login to both apps, and follow the in-app steps.

Use TruHu to:
• Ensure color accuracy across all your displays and projects
• Calibrate your screen on the go when working remotely
• Remove color discrepancies between team members’ work
• Create multiple ICC profiles for specific color temperatures 
• See real product colors when doing online shopping
• Ensure graphics-intensive apps, like video games, show accurate colors

Our mission is to bring color calibration to every photographer, designer, artist, or videographer out there, allowing for better, more professional work without the need for color guesswork.

* Must be used in conjunction with desktop application (Mac/Win) which includes an annual subscription fee.

### 1/5 — SCAM

*2026-06-12*

This app is trash. I used it several times and it never gives the same result twice. I purchased a yearly subscription shortly after the trial. It wasn’t until later I realize it doesn’t work correctly. I canceled my subscription and deleted my account. One year later I was charged again even though my account had been deleted. There is zero way to get in contact with the developer for billing support. Filed a dispute with Apple Card to reverse the charges. If the devs see this review, please contact me.

### 1/5 — Registrierung

*2026-06-05, version 3.3*

Warum zum Teufel brauche ich ein Konto? Ach und dann auch noch 39,99$ pro Jahr?

Antwort vom Entwickler:

„Sie benötigen ein Konto, damit wir das iPhone mit dem Desktop synchronisieren können. Und Sie müssen bezahlen, um das Entwicklungsteam zu unterstützen.“

Was für ein Unsinn!

### 2/5 — Good but Would be Great at Lower Cost

*2026-04-25*

This can’t quite calibrate at the same level as a hardware tool with a calibrated colorimeter but those are over $100. I definitely notice an improvement with TruHu.

That being said, the $39.99 price would be fair as a one time purchase. It’s incredibly steep as an annual fee considering its limitations in comparison to a colorimeter.

Update (April 2026): After regularly using the tool for a year, I stand by my initial assessment. I found it was often best to calibrate about 3 times per profile and compare each side-by-side to pick the most accurate profile. There will be differences and it isn’t a one-and-done tool. That being said, it is decent for what it is. $39.99 per year is absolutely too much. I will not be renewing at this time but would consider if the pricing model is re-evaluated. It’s definitely worth paying for, it just isn’t worth what they’re asking for on a recurring basis.

**Developer response:** Thank you for your feedback.  We are pretty proud of how TruHu stacks up against colorimeter-based monitor calibration.  I won't go into all the details here, but we do have a blog entry that addresses this.  Please have a look.  https://truhu.app/blog/colorimeter-based-monitor-calibration-vs-truhu/

### 4/5 — Calibration- on QD-OLED Moniter

*2026-04-09*

You know what I’m slightly more than content with the results which is weird. It did a somewhat good job and calibrating a warm/ in natural cool white issue I was having. By putting the color profile to 8000k it seemed to offset the warm color grading issue I was experiencing. I’m happy. $40 bucks per year is some BS to be honest but oh well

**Developer response:** Thanks for the thoughtful feedback.  In our experience, QD-OLED is more of a technology found in 40"+ TVs than in desktop monitors.  And TruHu doesn't support TVs.  What model monitor are you using?  If you achieved reasonable results, we are happy for you, but we didn't develop TruHu for this application.  

In terms of annual subscription, we think it's a very good deal compared to $200+ for a colorimeter-based monitor calibrator. We are continually improving TruHu to adapt to new iPhone models and new types of display technology, which is why it is a subscription.

### 1/5 — Don’t waste your time on any platform

*2026-01-06, version 3.1*

The solution (apparently) relies upon having an App running on both the iPhone and the Windows desktop. Having installed the App on the phone you will be asked to create an account. You then need to install the Desktop App and pair it with the iPhone App. Only trouble is the Desktop App doesn’t recognise the account created by the phone App, and if you try to create the account on the desktop App the fact you’ve already done it on the phone prevents you…

Or at least that’s my assumption of what the problem is. You don’t get anything helpful about the cause from the UI - just a red X by the email address (User ID) and an irritating beep. 

Poorly designed software with lousy pre-release QA… 

Don’t waste the 15-20 minutes of your life this App will steal.

### 5/5 — Solid, well priced color calibration for nonprofessionals

*2025-10-01*

This app and accompanying desktop software is great for casuals (like me) that enjoy viewing their monitors in accurate color. I also have to review figma assets and occasionally video edit for work — being able to accurately view color is quite useful.

I wouldn’t rely on TruHu for professional calibration but that’s not what it’s meant for anyway. I’d much rather pay for a simple app that takes 60 seconds to spit out decent color than drop hundreds on a colorimeter AND learn how to use complicated software that’s frankly unnecessary given my use case.

As an aside, expecting to get technology like this for free is mindboggling to me. I wonder if people who do so also download the free Canon Connect app and rate it one star because the camera doesn’t come with it?

### 1/5 — Irreführend

*2025-07-29, version 3.0*

Man wird erst nach der Kalibrierung des Monitors mit den dreisten 39.99$ pro Jahr konfrontiert

### 1/5 — Not supported

*2025-05-23*

The iPad app says it was free, so I download it. Download the desktop app because that’s needed, no indication of price. Then you want me to sign up (for reasons). Fine. Go to sign up only to find out that there is a price to use this. There is a free to try, so I click on that. I register for an account, go back to the iPad, log in, only to get an error “iPad is not a supported device”.

**Developer response:** Hi There - Yes TruHu does NOT Support iPads.  We cannot access the video LUT like we can on a Mac or Windows computer.  This is explained in our FAQ.  https://truhu.app/blog/truhu-faqs/

### 3/5 — Meh

*2025-05-09*

I knew going in, this wasn’t going to be a free app but 40 bucks for an annual subscription in the face of just buying the appropriate tool and having that for a lifetime seems a bit much.  Will keep an eye on this app as it definitely shows promise and for the price beats trying to edit photos against an uncalibrated monitor .  Just feel that for 100.00 bucks more to have the tool to use across multiple devices for a lifetime is a better option at this time.  Keep at it Devs.  You are on the right track, though

**Developer response:** Based upon user feedback like yours, we now clearly state this up front – * Must be used in conjunction with desktop application (Mac/Win) which includes an annual subscription fee. 

We think it's a very good deal compared to $200+ for a colorimeter-based monitor calibrator. We are continually improving TruHu to adapt to new iPhone models and new types of display technology, which is why it is a subscription.

One other thing to note, you always have your iPhone with you, which is not the case for your colorimeter.  So TruHu allows you to calibrate wherever and whenever you need it.

### 1/5 — App just doesn’t work

*2025-04-11*

I tried the windows app on 2 different PC’s and 2 different iPhones and the program would always get stuck on creating profile. Very bad that a $40 application doesn’t work at all.

**Developer response:** Hi There:  We have many happy customers on a variety of iPhones under both Windows and Mac PCs.  Feel free to send a message to support@truhu.app, and we can look into the details of your particular configuration.
