### 4/5 — Works well

*2026-03-29, version 3.20.1*

I was going to buy a light metre for my plants, but it’s so much nicer to have it on my phone. It works well, but I haven’t tested against an actual light metre so I’m assuming that it’s fairly accurate. I would agree with its readings based on where I have my plants located.

### 2/5 — Not accurate

*2025-03-06, version 3.20.1*

I tried to find my carnivorous plants on the list and they weren’t there, with grow lights turned off told me there was sufficient light but when I turned on my 40 watt grow lights it said insufficient light. Waste of money.

### 5/5 — Accurate and humble

*2024-05-30, version 3.20.1*

Very easy to use, not at all over complicated. The price is worth it.

### 1/5 — Beware

*2023-12-02, version 3.20.1*

Bought it and it doesn’t tell exact numbers, way off from normal meters you regularly buy

### 4/5 — Plant names unknown to non-English speakers

*2023-02-28, version 3.20.1*

There should be an option to search plants by their botanical name. Not being an English native speaker, I had no idea that the Tradescantia was called “Wandering dude” (…… why? 🤨🙄)
Same goes with several other plants, so not quite user friendly for us 😕

### 3/5 — Wish I hadn’t paid before trying

*2023-02-20, version 3.20.1*

It’s a cool concept, but it’s got a limited list of plants to check from and half of mine aren’t on it. This was recommended online as a free app, I wish I’d have tried it before paying.

### 4/5 — Great tool

*2023-01-16, version 3.20.1*

I have marked all my plants as favourites, but I have 2 plants that were not in the list of plants on the app. That’s why 4 stars. Also the app doesn’t talk about watering, it only talks about sunlight. Watering and a few more plants would be a good upgrade, but the app helps me to remember the name of my plants and I’ve moved some around to help them get the light that’s meant for each individual plant. If I’ve learned anything, you have to treat their needs individually.

### 5/5 — Pretty awesome!

*2022-11-18, version 3.20.1*

I usually randomly test plants to make sure they’re getting enough light. I live in a basement apartment and they only rely on grow lights. This is pretty accurate and so helpful. My plants are thriving in my conditions. People complain that there’s some plants missing but all you have to do is use the all plants feature and see how many fc there is and look up how much your plants need.

### 3/5 — Missing common plant!

*2022-10-01, version 3.20.0*

Cannabis plant is not one of the available options. 😕

### 1/5 — Pflanzenlicht

*2022-09-12, version 3.20.0*

Für mich leider unbrauchbar!
Für mich sind die tatsächlichen (nummerischen) Luxwerte wichtig.
