Awesome & EASY TV color accuracy check 6500k

Dude this app is extremely useful and quick if you want to check the color accuracy white balance of your television.I own a TV that really runs cold. Skin tones looked magenta. I don’t have the money or resources to get my TV professionally calibrated, so I adjusted the white balance of the TV myself until it perfectly matched the standard 6500K. Before it was 7500K. I have a professional OLED monitor that is VERY color accurate out of the box, and now there is absolutely no discernible difference between the TV and reference monitor in terms of accurate colors. This app is incredibly useful. One star has been knocked off because the app locks you out completely after 14 days if you don’t give them money. But at least if you DO give them money, you get what you pay for.

Response from developer

Thank you so much for taking the time to write such a detailed review - I'm really happy to hear you got your TV matched to the professional monitor at 6500K! Sorry for the 14 day limit - I need to make a living somehow. Thanks again for your review, it is very appreciated!

One Shot

I had nothing but ads after using it once.
Update: the developer had a courteous explanation to the proliferation of ads I encountered. One in which I understood and accepted. Changing my rating now.

Accurate CTM

Typically a special device is required to get accurate readings but this app does a great job using a standard iPhone15! The provided tips really improve accuracy as well. Well worth the one-time $10 cost!

Response from developer

Thank you so much for the kind words and the detailed review! Great that you confirmed the accuracy — that really means a lot to hear. And glad the tips are making a difference too. Enjoy the app!

Not free
