User Reviews for Light Meter LM-3000

Well done

I don’t go out of my way to write reviews for apps, but this was so handy for me today. I used it to quantify what portions of the building I do maintenance for “feels dark” I was able to pinpoint mismatched/incorrect/burnt out bulbs and now I’m noticing that many of my illuminated LED down lights are past their prime and no longer giving off adequate light.Very reasonable amount of use for the free trial and the “battery life” on the meter indicating how many uses are left is a nice touch.Included video link and supporting documents are excellent and very handy. Went ahead and purchased the full battery knowing I will certainly put this app to use again in the coming weeks. Seriously well done on this 👍🏾

Extremely helpful

Provides an objective measure of ambient light, giving me a sound basis for determining where I need more light — in my condo’s public spaces and in my own unit. Incredibly easy to use.

Great app to try for free with no subscription

People are so stupid complaining about the “out of battery” status, clearly it’s a clever way of telling people trial period is over, time to pay for someone else’s work. Do these morons work for free? I highly doubt it.

Have to have filter

The meter works well but you always have to have a filter (or white piece of paper) over the camera. I don’t always have that available when I want to use the meter. It’s an extra step that keeps me from using the app as much.

This is a scam

Free? When I first opened it I was required to make a light diffuser. Hmm okay. Easy enough. Once I got that attached to my iPhone the app popped up saying the meter ran out of battery and it would be $7.99 to purchase a lifetime battery. No options. My phone battery is 100% so that’s not the problem. This thing actually costs $7.99 if you want to use it. I wouldn’t be surprised if it continues to demand future purchases of something or other in order to use it. BTW, I have no idea if the light meter works. I never got that far.Update after developer’s response: I’m not confused about it being my phone battery. I’m confused how Apple lets you act like this is a free app but it’s only free to download, not free to use. It should be sold as an app for $7.99. It might even be worth it. But I’ll never know because I won’t trust a developer that says the app is free when it’s not.Update again after developer reply that this is a “try before you buy” app. No, it’s not. I didn’t get to try it. First it told me I needed the filter. So I made that. Then when I tried to use it, I got the message that the battery was empty and I needed to pay $7.99 for the lifetime battery. I never saw any light measurement at all. Why would I pay for this? You guys need to try using this from a phone not registered to one of you and see how it really works. Edit: I’m a systems analyst, software tester, support team member so I have some experience in this realm.

Totally Disappointed!

Greatly inconsistent readings. Every time the diffuser is removed and reapplied, the lumen readings are very different. They are inconsistent to the point of this app being unusable. I “cannot “ rely on the readings accuracy nor precision. I made, applied, and used the diffuser exactly as instructed. I was very exact that I placed the diffuser in the exact same position every time I reapplied it to my iPhone. After the diffuser wasn’t giving repeatable readings, I created a second diffuser and again received unrepeatable readings. Every time the diffuser is taken off and reapplied I received different readings. The difference in readings were sometimes over 100 lumens. We’ll there goes $7.99 down the drain.

Sneaky business.

Tell people you need to make a diffuser out of paper (simple to do) or app will not work.Tell people that the trial period is less than 24 hours, rather than telling people it works for "some time". In reality, there is no free trial. $7.99 is not that much. However, I don't want to do business with a company that deceptive.

Loved “try it before but it” and accuracy

I was looking for a free app, but decided to buy this one based on my experience (I still need to compare it against highly accurate light meter, but this performs good/better as compared to cheaper/mid-range light meters)

ShivDave, Feb 10, 2022

Easy to use and seems reasonably accurate

Tried on daylight (110k) and on 7500 lumen 40 degree led bulbs at 3 ft, got 15k instead of expected 21k, but probably partly because bulbs weren’t perfectly focused? Anyway, accurate enough for me! Just wish it had family sharing enabled, I’m going to get the other light meter app that does have it for the same price.

Absolutely Amazing

Most serious app I’ve ever seen although I’m a little bit doubtful about using camera to measure the accurate brightness since most camera have auto brightness and exposure control. It even requires a diffuser (don’t worry, just put a piece of paper on your front cam), which is quite professional unlike other app. Absolutely like it, thanks!Update: It is a very smart way to tell people the trial is over using a battery lol, love it and will buy it later
