Plant Light Meter Reviews

This is a simple, easy to use and straightforward tool for measuring light. It has a very attractive interface and updates to various light levels automatically. I’ve used another meter where you have to push a button to take a reading, but this does it on the fly, which is what I particularly like about it. My only suggestion is that it would be nice if one could use either the front or rear cameras.

I pointed the camera at the leaves of all of the plants in my very bright southwest sunroom. It read anywhere from too low-medium which is by no means accurate. When I hold my phone in front of the leaves but point the camera out towards the light I finally get a reading of bright, which I know the room to be. The room is full of cacti, succulents, and palms- all of which love bright light- and they are all thriving. Clearly there is more than enough light for the room to be considered bright but PlantLightMeter doesn’t read as such. I’m glad it was only $.99 to find out but still a rip off. Save your money.

People tend to give me plants that I know very little about simply because I love plants. PlantLightMeter is awesome to figure out good placement and give a good basic overview of a variety of plants. It’s SUPER easy to suggest additions too! I sent in a request at the contact email for a couple of tricky plants to be added and got a response the next day. The plants were added by the next update.

Thank you for updating PlantLightMeter . I had given it one star based upon the inaccuracies the update had caused but it’s back to working fine now. I tried it on natural light and two different grow lights and it provided readings that seemed to be more in line with what I would expect.

Thought I wasn’t going to like PlantLightMeter, but I was wrong. No more guessing, no more trying to figure out lumens, lux, candle 😝 Takes all the guesswork out!

Only complaint, not enough plants!! PLEASE add more. Even if it’s as a paid add on, it would be worth it!!

**Do not buy the update broke it.**

The original version was a bit tricky position, but it worked. In the new version PlantLightMeter attempts to take a reflective light reading instead of an ambient one, but it’s wildly inaccurate. Plants sitting on the window sill in direct sun often read as if they had lower light then plants 4-6 feet away from the nearest window. Plants with darker coloration read as if they have less light then plants directly next to them. PlantLightMeter also no longer supports plants with variegated or colorful leaves.

I’m always on the search for a truly FREE plant app. This one is awesome and I’d say pretty accurate for lighting. Wish it had a few more options for indoor plants. Like orchids.

It was so helpful before the recent update. When I moved into my new place a year ago it helped me figure out my lighting and where my plants, new and old, could thrive. And it worked! This new update is—and I don’t say this lightly—trash. It reads low or too low for every one of my plants, many of which PlantLightMeter told me before (and I know is true) are in bright or medium light. Pretty bummed to not have this tool at my disposal anymore!

I’ve had a kitchen full of flourishing plants for the past year - golden pothos, philodendrons, monsteras and quite a few others. Typically these like medium - low indirect light. Per PlantLightMeter, my lighting in my kitchen is “very low” where “no planes can survive for long.” Obviously, this is totally wrong. I also pointed PlantLightMeter directly at my full spectrum grow lights and also got the reading “very low.” Don’t waste your dollar this is app is a joke.

As a newby plant mom, I use PlantLightMeter all the time to find the best locations in the house for my plant babies. Definitely worth the couple of bucks I spent for it.

Love PlantLightMeter, super nice to be able to get different light readings using my phone! I would request support for trees commonly used for bonsai, like Chinese elm and juniper!

I love being able to monitor my plants’needs by repositioning them for their best light needs!

The fact that it only uses the back camera to measure light it makes no sense - how you read the light when you have to turn your phone down to use it - seems like they didn’t put much thought on the user experience or even use their product themselves

Upgraded from an iPhone 7plus and I can’t allow PlantLightMeter access to my camera. PlantLightMeter doesn’t even show in Apple settings. Please fix this issue bc PlantLightMeter works great...or at least it used to

I’m confused, every single reading in my house is reading too low, even in the brightest rooms in my house. This seems like a waste of money, considering I have plants all over and nothing has died due to inappropriate light.

My room gets I would personally say medium light and I tested it out and it said “very low.” I decided to really put it to the test by going to the brightest south facing window in my house and it said “low” still. Then I put it directly at the sun and it said “medium.” To me it seems off and it’s a waste of money just use your eyeballs to tell

Even without putting it on leaves, it works great. Worth the money

Bought this because it has decent reviews. Should have read more carefully, as it seems like it was better before an update. In any case, it’s useless. How can a plant right next to a west facing window get a reading of low?? Makes no sense. Don’t bother getting PlantLightMeter.

I have 2 plants in the exact same location. One is a light green and one is dark green. PlantLightMeter says the dark green one is in medium light & the lighter green one is high light. PlantLightMeter is obviously just measuring the darkness of the plant’s color, not the actual amount of light it is receiving.

I am very glad for PlantLightMeter
I love how easier it is to know
The right lighting thank you

This meter only works on green leaves and images taken at certain angles. It isn’t a reliable source to tell if your plants are getting enough light. And it definitely isn’t for artificial light. Overall an okay meter.
