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. **Developer response:** 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! ### 4/5 — One Shot *2026-05-16, version 3.10.0* 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. ### 5/5 — Accurate CTM *2026-05-07* 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! **Developer response:** 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! ### 5/5 — 최곱니다 *2026-04-22* 집 조명 고르고 있는데 너무 도움됩니다 **Developer response:** 친절한 리뷰 정말 감사합니다! Kelvin Meter가 집에 맞는 조명을 찾는 데 도움이 되고 있다니 정말 기쁩니다! ### 5/5 — super *2026-04-13* funktioniert **Developer response:** Vielen Dank für die 5 Sterne! Es freut mich sehr, dass das Kelvin Meter seinen Zweck für Sie erfüllt. ### 5/5 — Super handy!!!! *2026-04-13, version 3.9.0* This is a super useful tool ### 5/5 — Cinematographer *2026-04-01* When you walk into a room and there is no certainty what color temperature (Kelvins) is your source lighting or sources that are coming into the scene, this tool is an easy way to start knowing! I use the Kelvin Meter to measure color temperature at every shoot and it is very close if not exact most of the times. **Developer response:** Thank you so much for this wonderful review! It's really great to hear from a cinematographer using Kelvin Meter on set. Great that you confirmed its accuracy! Really appreciate you taking the time to share your experience! ### 5/5 — Great *2026-04-01, version 3.9.0* Ended up buying both the nits meter and this. Very handy and surprisingly accurate ### 4/5 — Schnelle Analyse von Farbtemperatur *2026-03-12* Einfach zu bedienen **Developer response:** Vielen Dank für Ihre Bewertung! Es freut mich, dass Kelvin Meter Ihnen eine schnelle und einfache Farbtemperaturanalyse bietet. Falls Sie jemals Vorschläge haben, können Sie uns gerne unter apps@contechity.com kontaktieren! ### 5/5 — Easy, effective and exact *2026-03-08, version 3.8.3* Is really a good user interface, uses the native architecture of the camera and is really accurate, great for art, stage and making sure the colours you use really reach their full potential ### 5/5 — Excellent App to get ideal white balance *2026-02-04, version 3.8.2* I found this app to be very good indeed - easy and intuitive to use and gives great results. I’m looking forward to an updated version that provides additional green-magenta bias data for my OM Systems OM3 although even without this the app delivers great results. Despite how good AWB is on many modern cameras it’s so much better and easier to get the right balance when shooting rather than trying to correct in post processing. ### 3/5 — Paid for app/ updated/ then had to review??? *2026-01-31, version 3.8.2* I paid for the app then I updated the app and then it has a request to rate app and that request will not go away. ### 5/5 — Top Photography App *2026-01-30, version 3.8.2* Love this app, being able to take a reading of light in the room for what flash gel correction I need to apply * in live time* is fab. Also gives recommended white balance mode for camera which means less thinking time required. ### 5/5 — 성능 *2026-01-26, version 3.8.2* 최고임 ### 5/5 — Great *2026-01-24, version 3.8.2* Fun to use. Seems good ### 4/5 — Student *2026-01-23, version 3.8.2* It works! ### 5/5 — Light app *2026-01-14, version 3.8.2* Very helpful to test light source and reflected light ### 5/5 — Nicely accurate, better than all the others! *2026-01-11* I downloaded 3-4 kelvin meters and all the others were quite off on the warm side. I was reluctant to sign up for a 3 day trial with this one but soon realized that it is worth it and miles better than the other ones. Great for shooting with cameras that either have an auto white balance that doesn’t tell you what the measurement is or cameras that need to be set with a kelvin temp manually. **Developer response:** Really appreciate your detailed feedback from your comparative analysis! Thanks a lot for sharing! ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2026-02-10, version 3.8.2* I can not figure how to use this ### 1/5 — Cannot test without subscription *2025-11-28, version 3.8.0* When I start the app I get presented with screen to buy subscription or lifetime. But when I click “Close” or “x” button it just goes to settings. If I go back to the app main screen I get the same screen to buy subscription and I cannot test the app. ### 1/5 — Paywall blocking everything *2025-10-14, version 3.7.0* Just updated the latest version. Within 2 seconds the app shows a full screen paywall to upgrade or trial paid version, but there’s no way to get out of that or use the app. Useless at this point. Doesn’t Apple test apps anymore? ### 1/5 — 酷いアプリです。Terrible app. *2025-07-16* 手持ちの色彩照度計と比較したところ出鱈目な数値でした。 **Developer response:** 携帯電話で数値が不正確な場合は、アプリのキャリブレーション機能をご利用ください。 ありがとうございます！ apps@contechity.com ### 1/5 — Scam *2025-07-01, version 3.5.0* This app is a scam totally useless and waste of phone space wants money to do anything with it I buy a legitimate meter first ### 1/5 — Man muss bezahlen *2025-01-09* Man muss direkt zahlen um die App nutzen zu können. **Developer response:** Nicht wahr. Die App kann einige Wochen lang kostenlos mit allen Funktionen genutzt werden, ohne dass eine Anmeldung erforderlich ist. Wenn Sie die App danach weiterhin nutzen möchten, ist eine einmalige Gebühr oder ein Abonnement erforderlich. Falls Sie die App nicht testen konnten, senden Sie mir bitte eine E-Mail an apps@contechity.com, und ich helfe Ihnen gerne weiter. Bitte ziehen Sie in Betracht, die Bewertung zu aktualisieren. Vielen Dank! ### 1/5 — Not free *2024-11-08, version 3.0.0* It forces you to choose a paid option and is unusable otherwise ### 1/5 — Not accurate in wide ranges! *2024-09-21, version 2.2.3* Not worth the money. ### 1/5 — Am I going to be billed? I DONT know… *2023-10-11* After installing, ( not before ) I’m hit with subscription. It’s not the money, it’s the complete lack of mention that this is a subscription. The ONLY option is ‘click to continue’ followed by a ‘cancel anytime’ note. But, where is the ‘cancel’ button?! Yeah, the app might be good, but I don’t trust anyone who isnt upfront about a few bucks. No go here. **Developer response:** Thanks for your feedback! I apologize for the confusion - just click the "Close" button to try the app for a few weeks without signing up. If you decide to subscribe, there is a link saying "Handle or Cancel Ongoing Subscription" where you can cancel your subscription at any time. (There is also a pay once-and-for-all option.) Thanks again for pointing out that this is unclear - I will try to make this more clear. ### 2/5 — Not free *2026-04-14, version 3.9.0* Doesn’t let you do anything unless you get an in-app purchase. If it’s not a free app, don’t list it as a free app! ## Most praised reviews (10 highest-rated) ### 5/5 — Surprisingly accurate *2026-08-17* I have a Sekonic C-800 and this app tracks very closely with it. Very impressive! This is very handy when I just need a quick reading and don’t want to take out my Sekonic from the flight case yet. **Developer response:** Comparing favorably to a Sekonic C-800 is great to hear - appreciate you taking the time to share this! ### 5/5 — Smarter Helfer *2026-08-03* Ich benutze den „Kelvin Meter“ in der Grundversion seit einigen Monaten und bin wirklich begeistert. Unkompliziert und schnell kann ich mit der App einen Weißabgleich machen. Ich setze die App vor allem in der Kombi mit meiner Osmo Action ein. Sauberes Ausgangsmaterial spart viel Zeit im Videoschnitt und steigert die Qualität des Videos deutlich! Lohnenswert! **Developer response:** Vielen Dank für diese Bewertung! Es freut mich sehr zu hören, dass Kelvin Meter sich nahtlos in Ihren Workflow mit der Osmo Action einfügt. Ja, den Weißabgleich direkt in der Kamera richtig einzustellen spart jede Menge Zeit in der Nachbearbeitung, und genau das ist der praktische Mehrwert, den ich mir von der App erhoffe. Ich schätze es sehr, dass Sie sich die Zeit genommen haben, Ihre Erfahrungen zu teilen! ### 5/5 — Perfect *2026-07-30* Great app! Easy to use and gives consistent readings which has been very helpful in matching the different ambient lights in my home. The meter starts as soon as you open the app so you don’t have to navigate through any menus. Well done! **Developer response:** Thank you so much for the kind words! Really glad the consistent readings have been useful for matching ambient lights. If there is anything I can improve for your use case feel free to write to me at apps@contechity.com. Thanks again! ### 5/5 — Very handy *2026-07-22, version 3.12.0* Great tool ### 5/5 — Why doesn’t my digital do this? *2026-07-12, version 3.12.0* This app is terrific and easy to use. A must app for any serious photographer ### 5/5 — Recommended *2026-06-20, version 3.11.0* The app works really well and the creator will respond quickly if there are any questions. Very happy to find a Kelvin’s meter! Thanks ### 5/5 — Бесплатно быстро посмотрел, спасибо *2026-06-19, version 3.11.0* Все работает спасибо. ### 5/5 — Excellent meter *2026-06-16, version 3.11.0* Excellent meter for a beginner. Easy to use with good information. This app has been a great asset for My work. Thank you. ### 5/5 — Accurate and really useful *2026-06-14, version 3.11.0* Title says it all really. I ditched my aging Minolta Color Meter in favour of this Kelvin Meter because it's more accurate and very easy to use. Enables me to match three different cameras with confidence. Good support too. ### 5/5 — Up to the task *2026-06-06, version 3.11.0* Seems accurate enough --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
