Бесполезное приложение

У меня давно оно было скачено и я пользовалась иногда для проверки люксов. Сейчас наступила зима, купили лампы. Иии села какая-то внутрення батарея приложения и чтобы ее зарядить надо купить подписку втф
Я даже не знаю почему она села…. Проще купить на маркете нормальный люксометр, потому что подписка стоит дороже чем сам прибор. 🤡
На 1 или 2 раза приложения хватит , но бред полный. Можно просто вставить рекламу в приложение, а не скачать на раз и удалить

Response from developer

Ксения, спасибо, что так долго пользуетесь приложением! 💡 Батарея села не из-за сбоя: «Стартовая батарея» — это бесплатный пробный период минимум на два дня измерений (считаются только дни, когда вы действительно измеряете свет). При редких проверках люксов он растянулся надолго, а теперь закончился. Подписка — не единственный вариант: можно разово зарядить батарею на 48 часов или один раз купить безлимитную батарею — навсегда, без подписки. Люксометр по цене безлимитной батареи найти можно, но точным он не будет — хороший прибор стоит от 150 $. LM-3000 откалиброван в лаборатории отдельно под каждую модель iPhone и iPad, а телефон всегда с собой. Рекламы нет намеренно: она раздражает, а рекламные сети передают данные пользователей третьим лицам. Анжела и команда Lightray

Excellent App with Room for Innovation

Great work by the developer! The app is well-designed and very useful. One suggestion would be to add surface luminance (cd/m²) measurement using the smartphone’s back camera through OECF-based calibration or reference luminance meter calibration. This could be valuable for road safety research.

Response from developer

Thank you, Raoniar! Glad the app is useful to you 💡 Ask explained to you already via email: Luminance from the rear camera is physically feasible, and road lighting (EN 13201) is a good use case for it. It would need its own calibration chain per device model and lens, though (absolute factor, spectral correction per light source, veiling glare), so it isn't on our roadmap for now. But thanks for sharing! We read every review, and this suggestion is definitely noted. Dennis and the Lightray team

Overpriced

Gets a 3/5 since I can buy an actual light meter for the same price on Amazon. Y’all made a cheap bit of code and your pricing should reflect that.

I’m back!

It was really useful! Thanks

False positive review bombs

Stay away. This app charges 7.99 after using it for a few minutes and locks you out of ALL features

Faulty measurements indoor

Sorry, but the „accurate measurement” seems untrue indoors. With paper diffuser applied I gradually was bringing an LED lamp closer. The lux amount was also changing from 6 to 18 gradually, as expected, but after that it jumped to 242 (??) no matter how minute the lamp movement was. This weird behavior was consistent with moving the lamp away - the meter suddenly jumped back to 18 lux. Nothing in between!
I’ve got a competing app, used front camera and the same paper diffuser. Its behavior was exactly as expected - the lux flow was changing gradually with distance, no weird jumps. Thus, my phone, my camera, the lamp, etc. are OK. The only difference was the app.

Response from developer

Hi box of apples, You are right: a reading that goes from 18 to 242 lux with nothing in between is not how a light meter should behave, and it is not how the LM-3000 behaves on any of the over 200 devices I've tested the app on 😅. This means something in this particular setup is off, and I'd would like to find out what. Please write to support@lightray.io with your iPhone model, the iOS version and, ideally, a short screen recording of the jump. I will look into it right away. On the comparison: a value that changes smoothly with distance is a good sign, but it is not the same as an accurate value. Any camera app can turn exposure data into a number that moves in the right direction. Whether that number is the right one is a different question, and it is the one we have spent the last seven years on: every iPhone model is measured and calibrated in our optics lab against a professional reference equipment. If you have access to a quality lux meter, put both apps next to it. That is the comparison we welcome. If you could also mention the name of the "competing app" I could analyze it as well and also address that in my response :) Dennis and the Lightray team

Good

Seems really useful(I haven’t used it really yet just playing around with it but will write another review when I done) but can’t change from selfie camera to back camera.

Great app

Does what it says

Response from developer

Hi Jay Gyl, Thank you for the five stars! "Does what it says" is honestly the best compliment a measuring instrument can get 😃 Best regards, Dominik and the Lightray team

Ерунда полная

Из за рекламы которая маячит сразу при включении и не уходит,требуя платной подписки,пользоваться не стала.

Response from developer

Здравствуйте, MonicBell! Жаль, что первое впечатление оказалось таким — но один момент важно прояснить: рекламы в LM-3000 нет вообще. Экран, который Вы видели, это «заряд батареи» приложения, то есть варианты оплаты. И подписка — лишь один из них: есть разовая покупка на два дня (≈$0,99) и разовая покупка навсегда (≈$19,99). При установке приложение даёт бесплатную «стартовую батарею» минимум на два активных дня измерений, так что сразу после установки измерять можно бесплатно. Если экран не закрывается и не даёт работать — так быть не должно. Напишите нам на support@lightray.io с моделью iPhone и версией iOS, мы разберёмся. Как устроена «батарея», подробно здесь: lightray.io/lightmeter/#purchases-explained С уважением, Dennis и команда Lightray

Nah this a’int it

Just make a light ad based version for hobbyists and occasional use; the battery stuff is actually just annoying and stupid and not as clever as they would like you to think and needlessly complex. Keep the pro full version as is.

Good app but

Meter worked well but forced me to purchase time to continue use.

The best ever light meter only available in this platform

Absolutely correct accuracy and 100% authentic readings and most importantly available in free this is an awesome app the first time im reviewing a good application in app store hats off developers

Response from developer

Hi Rohit54, Thank you so much for your review and the very kind words 😍 It makes us really happy to hear that you appreciate the hard work we've put into the app 🙏 The highest possible accuracy is our main goal, and it's great to hear that our efforts are valued 🫶 All the best, Angela and the Lightray team

23 EUR für 1 Funktion

Feine super App, die eine einzige Aufgabe hatte und diese super erfüllt hat. Jetzt auf einmal, obwohl sie im App Store als kostenfrei und ohne in-App-Käufe und ohne Abo Modell gelistet ist. Entweder ein Abo oder ein Einmalpreis von 23 € ist schon echt sehr sportlich und spiegelt leider nicht den Wert der relevanten Funktion wider, die sich auch nie ändern wird.

Hallo Kasatschok, Es freut mich sehr zu hören, dass dir unsere App und ihre Funktionen gefallen! Vielen Dank für dein Feedback 🙏 Es stimmt aber nicht, dass sie im App Store als kostenfrei aufgeführt ist. In unserer App-Beschreibung sind die gratis Testperiode von 2 Tagen und die Kaufoptionen beschrieben. Ausserdem markiert Apple automatisch alle Apps, die in-app Käufe beinhalten. Du findest den Preis von 23 Euro zu teuer für das, was du kriegst. Das Preisempfinden ist natürlich subjektiv, unserer Meinung nach ist das Preis-Leistungs-Verhältnis unübertreffbar: Du kriegst ein genaues Lichtmessgerät mit vielen praktischen Funktionen und regelmässigen Updates und Erweiterungen, für deine Hosentasche. Oder sogar günstiger, wenn du dich für eine kürzere Verwendung entscheidest. Aber wie gesagt, da gehen die Meinungen auseinander, und das ist okay. Liebe Grüsse und alles Gute, Angela und das Lightray Team

Tired of subscriptions

Works well enough before your virtual light meter “runs out of battery” and you have to pay to recharge it or it won’t work. This shouldn’t be a subscription.

Trial only

They don’t tell you this is only a short trial. Two stars for the obfuscation.

Не понятно

В чем смысл такой платы за приложение, если прибор люксометр можно купить за 1000-1500 руб. вы там куку?

Response from developer

Здравствуйте Milabone, Спасибо за ваш отзыв. Ценообразование – сложный вопрос, и мы понимаем, что не можем угодить всем. Мы считаем, что нашли справедливое решение. Все приложение можно протестировать бесплатно, и если оно вам понравится, вы сможете выбрать подходящий вариант из нескольких предложенных. Вы получите точный светомер со множеством практичных функций и регулярными обновлениями — и все это за небольшую цену! По нашему опыту, недорогие светомеры, о которых вы говорите, очень неточные. Но если вы нашли такой, который соответствует вашим требованиям, я, конечно, рада за вас☺️ С уважением, Анжела и команда Lightray

Data

Bro this don’t work it’s sometimes work and sometimes doesn’t I’m doing a project and this app is not helping me achieve all the data I want

49 hour battery runs on a timer?

Hello I needed to have a mic meter for a job I was working on. I downloaded your app and thought that 48 hours of battery power would be plenty to use. Now having this mindset I went to open my light meter for the first time and use it this week after I purchased the 48hr 2 days before. To my surprise my battery was empty and I was not able to use the meter I had paid for. This really is not how an actual physical battery works. I feel taken for and a fool for spending any money on this to not be able to use. I apologize if this was clearly stated in the purchase agreement. But ethically this is not good. Thanks but no thanks?

Response from developer

Hello Spider-Jon, Thank you for your feedback and detailed description of your concern. I'm sorry there was a misunderstanding. In our opinion, it is clear that the Single Charge charges the battery for 48 hours from the time of purchase, not only for the hours of actual app use. We also state this in our FAQs (https://lightray.io/lightmeter/#faq). However, of course, we can't expect all of our users to scroll through them in advance, and I can understand how the confusion happened. We will discuss this within the team and, if applicable, adjust our wording to make it clearer. In any case, it is not our goal to mislead our users, and we sincerely apologize. Please contact support@lightray.io so that we can find a solution. Best regards, Angela and the Lightay Team

Good, but not free

The app is not free you can download, but you cannot use without paying

super bad app

It ask for you to buy the filter once you start to used it and true you can use paper to avoid it but the reading is really inaccurate. After download a week, it says it is “out of battery” and you need pay to recharge it. Just charge at beginning instead of pretend to be free
