Hi there, Thank you so much for your feedback and for spreading the word! 📣💌 Cool to hear what you use the app for and what you especially like! This helps us in deciding how to further develop the app 💡🤓 Kind regards, Angela and the Lightray team

Worst app ever

Terrible and locks you out. Don’t bother downloading.

Response from developer

Hi Danny Reviews Apps, Thank you for your feedback. I am not sure, what you mean by "locks you out". Do you mean the pop-up telling you that a diffuser is required? You can’t click it away but as soon as your camera recognizes a diffuser, the pop-up will disappear. We do this on purpose because the diffuser is essential to get accurate measuring results. Otherwise, please reach out to us via support@lightray.io and we’d be happy to help you out 🙂 Kind regards, Angela and the Lightray team

Day 1 Light Meter LM-3000 TM

This is day 1 using the Light Meter LM-3000 app. Worked 6 hours on grow shelving and light set up. The app worked great. I have 3 different LED shop lights installed and the light meter was consistent based on specifications of the light and the placement. So far so good. Thanks.

Hi True Plant, Thank you so much for your feedback and the insight into how you use our app!🙏 We have a specific app for plant growers, you might want to check it out too! It’s called Photone 🌱🤓 Happy growing, Angela and the Lightray team

Yeah. A scam.

It was pretty cool. I work in a calibration lab and deal with real ones. But then, I decide to use it and I can’t without buying some kind of battery app. I realize everyone needs to earn a living from their labors however, let me know in a very obvious manner, that this is a free trial which will eventually end. I saw nothing to indicate that. I feel “tricked”. They need to fix that and they’ll have better ratings.

Hi Teddytoons, Thank you for your feedback. What you’re describing is the regular free trial ending, of which there’s info throughout the app. We have put in a lot of work to develop this app and spent hours and hours refining it in our lab in Switzerland. We believe that our highly trained employees deserve a fair salary and that users like you don’t want to look at annoying ads while using the app. We therefore think that offering a free trial to a paid app is appropriate but of course, you are free to have a different opinion. Kind regards, Angela and the Lightray team

Not a spot meter but works

Caught traveling without a meter and been exploring iPhone meters. This one’s not much use to me bc it has no spot metering. But for a cheap to free app, it’s not bad. Not sure how accurate it is, but it’s probably close enough to get you in the ballpark if you’re shooting old film cameras and not interested in distant shots.

Hi Vermiculite, Thank you for your feedback. Please beware that our app is not a light meter for photography but rather for general applications requiring accurate illuminance (lux / fc) measurements. Therefore, there are no features for spot metering in the app. Given that it’s used correctly (f.e. first of all using a diffuser), I can promise you highly accurate illuminance measurements in case you’ll ever need that 🤓 Best regards, Angela and the Lightray team

Great customer service!

Incredibly responsive and helpful company! They were extremely patient with my questions and went out of their way to make the information accessible and understandable.

Hey Light Peter, Thank you so much for this feedback! It's nice to know that our work is appreciated! 🤗🙏 Don't hesitate to contact us again if there's anything we can help you with 😊 All the best, Angela and the Lightray team

Annoying

Most annoying app ever. All you get is a message stating diffuser missing which does not allow the app to work. Can not even access in app purchases. Pointless.

Response from developer

Dear Rob art critic, Thank you for your feedback. I'm sorry that you feel that way. It's the laws of physics that a diffuser is needed to measure light. The pop-up is intended as we don't want people to get false data or spend money before they know how the app works. It's quick and easy though to build a diffuser yourself, all you need is a bit of paper and the instructions in this video: https://www.youtube.com/watch?v=CaNiEF_QEmE Best regards, Angela and the Lightray team

Waste of time . Won’t work without purchasing diffuser

Scam

Response from developer

Hi peterdeez, Thank you for your feedback. It‘s not quite true though. You don‘t have to buy a diffuser for the app to work. You can easily build one yourself in under a minute, as described here: https://www.youtube.com/watch?v=07SxrmjSqGc&cc_load_policy=1&v=watch Unfortunately, laws of physics dictate the usage of a diffuser for any method of measuring light. But we feel that with the possibility of the one made out of paper we‘ve found a very easy solution for this issue. Best regards, Angela and the Lightray team

Useful app that seems to be accurate

I purchased this app because it was cheaper than buying a dedicated light meter. The app is used to measure light intensity I am exposed to during the morning to ensure that I sleep better at night. I am using an iPhone XR with a thick OtterBox Commuter case. Technical support for the app advised that in this situation, for the diffuser, I should tape a piece of paper over the front camera instead of creating a paper loop. The app is informative and the technical support was helpful.

Hi iDrinkKoolAid Thank you so much for your review and sharing your experience with the community. I’m very glad that the app works so well for you and it makes me proud that we can help people with their sleep! Also it makes me happy to hear that you felt that our support was helpful. Good night, sleep well😴 Angela and the Lightray team

Definitely getting something right!

Pointing it up at my plain white ceiling since I don’t have a diffuser. With my lamps on, 200 lux; with my corn bulbs on, 800 lux; with both on, just what you’d want it to say, 1000 lux. So it’s definitely better than I expected.

Response from developer

Hi spencerrose1, Thank you very much for the 5 stars and telling us a bit about how you're using the app. I'm glad you get such satisfactory measurements. For the best and most stable results I still recommend that you use a diffuser. You can make one in less than a minute or get one of our diffuser accessories.
