for people who keep losing plants

Your watering isn't the problem. Your light is.

Every plant app tells you when to water. None of them can tell you whether that corner is quietly starving your monstera. lightfit reads the actual light in any spot and gives every plant you own a straight verdict — thrive here, or sulk here.

how it works

Point. Read. Verdict.

01

Point your phone

At the windowsill, the shelf, that corner you're unsure about. Ten seconds.

02

Get a real reading

Actual light, tracked across the day. A number — not "bright indirect," whatever that means.

03

Every plant answers

Thrive or sulk, per plant, per spot — and where each one would honestly do better.

why this exists

The internet can't agree on what "bright indirect" means.

"PPFD might display 750 at 10AM… then 10 at 1PM… which number should I be using? How do I use the number?"

r/houseplants — light-meter owner, still lost

"I've tried more light and less light."

r/plantclinic — on a dying jade, 393 upvotes

"Get a light meter and figure out quantitatively how much light your plants are really getting. It upped my plant game to the next level."

r/houseplants — the advice lightfit automates

One number. One verdict. No more guessing.

No paywalled light features. No 40-feature plant OS. One thing, done properly.
