When replacing burned out sources, it's important to match the color temp of the replacement with other existing sources. So I downloaded this app in hopes that it would be a handy tool. Not so much. I tested the app with two banks of fluorescent tubes, each was clearly either daylight or a much warmer color. If I could upload a photo, you would easily see the difference. Yet this app rated them at essentially the same degrees Kelvin, 5150 (actual: 7 degrees different). Maybe the eye and camera is very sensitive to color shifts and consequently it's too much to ask of an inexpensive app to resolve the difference. But using this app to chose replacement bulbs in a home or office would give unreliable results in matching sources. ### 1/5 — Crap *2015-11-04* Crashes straight back to home screen every time. Emailed for support and got no reply. ### 1/5 — NON FUNZIONA !!! *2015-11-04, version 1.1* Quando apro l'app crasha subito. Potreste fare un altro aggiornamento per cortesia ? Grazie. Sandro Litargini ### 1/5 — Useless *2015-11-04* Doesn't work. Goes straight back to home screen. Tesla, light meter and battery monitor seem OK, but the lux meter is rubbish. ### 1/5 — Quits on launch *2015-10-14* App straight up doesn't work, as soon as I press start it quits (iPhone 6s). Waste of money. ### 1/5 — Lux Metet *2015-10-07, version 1.0* Doesn't work on 10-5-2015 as described. Just trashed 2 bucks. Wanted no stars but couldn't enter that. ### 1/5 — Broken. Please fix. *2015-10-06* Does not work and crashes when I hit the start button. iOS 9.0.2 on iPhone 6S Plus. ### 1/5 — 1 *2015-10-04* Не работает, не тратьте свои деньги ### 1/5 — Not worthed *2015-09-28* I just bought this app and immediately I realized that I made a mistake, readings are off around 350 luxes from a real meter, don't waste your money!! ### 1/5 — Worthless *2015-09-27* Reading jumps all over the place. Useless and worthless. I deleted it and it wasn't free!! ### 4/5 — Excellent tool for home or work *2015-09-18* I have been using this at home and at work to set light intensity to help reduce electricity cost. ### 4/5 — Nice indicator *2015-08-21, version 1.0* Simple to use app. I am guessing it's more of an indicator rather than an absolute measure. It showed me that my new replacement LED tube ( to replace fluorescent unit) wasn't as bright as the fluorescent tube even though I thought it was brighter (still LED is better as no flicker). It showed manufacturers claims that the output was the same wasn't true. Some inconsistencies with the readings, but probably more to do with the phone hardware. Another app to get more out of the phone. Cheaper than a proper meter, and you probably have your phone with you all the time so it's there when you are trying to make your mind up in the lighting store! ### 3/5 — Works decent enough but has a few bugs *2015-07-03* This works well enough to use if you don't have any lux meters in hand. I currently have the pocket sized ex tech low range meter. This is my go to meter. Unfortunately the phones meter fluctuates a little too much for me and is usually a little off with the measurements. I'll try using this at night for a parking lot we are working on to help us with installing light posts. Also, when I click the info button it has an 'x' to go back. Every time I click the info button to land on that page the 'x' moves location. The text should also take up the width of the phone and not just 2/3 of it. Currently running on an iPhone 6 plus. ## Most critical reviews (10 lowest-rated) ### 1/5 — 환불바랍니다(사용안됨) *2016-12-18* 시용안되요 환불바랍니다 ### 1/5 — Too inconsistent to be worth much. *2016-12-08* We cannot generate consistent readings with this App. One of our consulting engineers placed a professional meter next to the App and got widely different readings. We didn't expect the App to be super accurate but hoped that it would give our designers "ball park" readings. The reality is it appears to be no where near close. The same App on different iPhones generates different readings in the same location. Does this camera generate readings from the front or back camera? Do you place it on the lit surface or focus the camera on the surface? The documentation is lacking so it hard to know. ### 1/5 — Useless *2016-10-24, version 1.3* Only works with rear cam. Can't place it on surface and fix or see the data because the cam is touching the surface. !! Useless. ### 1/5 — CRAP *2016-09-21* Send me my money back! ### 1/5 — Not really? *2016-03-08* Its number is different from a Tonda 1010B LUX meter at my hand by about half of the physical LUX meter. I think I just wasted this money. ### 1/5 — Che cavolata *2016-02-28, version 1.3* Messo vicino ad un misuratore non si avvicina neppure per sogno! Soldi buttati via. Chissà quando si potrà farsi rendere i soldi come Google ### 1/5 — Paid and regretted. *2016-02-23* Simply not working. Support almost none, not even a proper instruction, just said apps is too simple and not require any instruction. Paid and regretted ### 1/5 — Don't waste your money *2016-02-22* It app is not at all intuitive and responds like a sloth. ### 1/5 — Yeababy123 *2015-11-13* Crashes - have not seen it open yet ### 1/5 — Be careful *2015-11-07* Apple should pay more attention screening the apps before send then to the market. This app is useless. It don't have no features, no way to calibrate, to adjust for accuracy, no a single bottom. The setting bottom send you to hell and the app stop working without way to go back to the meter screen. This app is a insult to customers. ## Most praised reviews (10 highest-rated) ### 5/5 — Correct result *2015-12-04* I have to tell you; this app works just as well as a professional device.
