Light Meter LM-3000 App Reviews

This works perfectly and I am super happy that it has both reading instructions AND a video this app is amazing and is literally perfect for science research for light and bioluminescence it is also easy to use 10/10 love the app

I never write reviews I’m usually just a guy who downloads something and if I like it great! And if I don’t like it that’s just too bad. But this is the ONLY light meter app that told me I need a diffuser! I was always so confused on why my grow lights were only measured at 100 foot candles. 10/10 app I love it

THANK YOU for letting us make a one-time purchase instead of a subscription!! I just delete apps that require subscriptions lol. This light meter is well-designed (you just need a piece of paper as a diffuser), easy to use, and seems pretty accurate when comparing it to physical light meters. I also like that I was able to try it out several times before paying.

Not having the budget for a pricey light meter I looked into potential apps and found this one. I read the developers description and the app manual and followed the directions and violà - it worked like a charm!!! It was SO EASY to try out the app prior to paying the very small, very reasonable one-time price!! As long as you aren’t an idiot who lacks self-awareness, and take the 1-2 minutes to read the description and instructions, then this is the app for you!!

This is probably the best-designed app I've ever gotten

Works well but it isn’t free it’s just a trial offer.

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.

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.

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.

I’m not one to write reviews very often, but I have to commend this developer for such a high quality app with superb functionality. Furthermore, their customer service is fantastic and very responsive.

I've tested a dozen lux meter apps against mid-tier hardware light meter. This app matched the readings of the real light meter +/- a few percent using a paper diffuser stuck on with scotch tape. All of the other light meter apps were basically just random number generators. The trick to getting this app to be super accurate is to use the right paper for a diffuser. Use 22 lb printer paper, like the manual says. Not 20 lb paper. Not 24 lb paper. Use 22 lb paper. Nice job guys!

I’ve paid for the app, so I’d expect the pop-up for the diffuser to stop. I’d love to give the app 5-stars, but this is just so annoying and makes it unbearable to use. Please fix.

Says you need a diffuser and stops working immediately BUT it is a simple thing to add. Just means you have to have it with you whenever you want to use the app.

For science class

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.

Maybe I’m the outlier for the usage here but I need it to use the regular iPhone camera the front camera is totally useless for my needs.
