How to read your window's light in under a minute.
Compass direction is a starting point. Depth from the glass, obstructions, and time of year change everything. Here's how to think about it.
Map your windows once. Every watering reminder and Doctor consultation is grounded in your specific light and each plant's history - not a generic care sheet.
Take one photo. Planterra identifies the species and sets a care schedule.
Walk to each window and tap once. Planterra learns your light in a minute per window.
Reminders arrive when your plants need them. Ask the Doctor when something looks off.
Just walk to each window once and tap. That's it - from then on, Planterra knows which way it faces and follows the sun as it moves through your home, hour by hour, season by season. It'll tell you which window gets that perfect early-afternoon light, and which corner goes dim the moment winter hits.
No other plant app does this. Because no other plant app knows your home.
Just walk to each window once and tap. Planterra tracks how the sun moves through your home all year - no other plant app knows your rooms like this.
How sun mapping works
Every plant gets a patient card - a running record of what's been diagnosed, what you tried, what worked. The Doctor reads it before every reply, so you never start over.
Yellow leaves in month three get treated as a follow-up to overwatering in month one - not a stranger's first appointment.

Some spots that look bright are actually dim. Some corners you'd never consider are perfect for a shade-loving plant. Point your phone anywhere - Planterra reads the real light level and suggests plants that would thrive there.

How the meter worksThe light was always there.
We just built a way to see it.
If you recognise yourself in any of these, you're in the right place.
Killed the same succulent three times. You want a system that catches you before the fourth.
Just brought home your first Monstera. You need plain instructions, not "vibes."
30+ plants, 4 rooms, tired of spreadsheets. You want per-plant memory that scales.
Already own a lux meter and a hygrometer. You want numbers, not "bright indirect light."
Planterra remembers your Monstera's history - what you tried in March, what actually worked in April, why you switched pots in June. The Doctor reads that story before every single reply.
It's the first app that actually tracks my plants over time. I really like the window compass feature, and I'm genuinely using the watering and fertilising reminders - not just ignoring them.
I'm pretty bad with plants, honestly. Planterra told me exactly where to put each one so it would actually thrive, and how much to water it. No more guessing.
I love giving my plants ridiculous names - and the fact that Planterra identifies them almost instantly makes the whole thing so much more fun.
The Plant Doctor is my favourite part, I know I'll keep coming back to it. Hoping to see more gamified features soon so I can compare what I've found with other users.
Great design, genuinely useful features. I'm already recommending it to friends and family.

Not a hit piece - a fair, side-by-side of what the category does versus what Planterra was specifically built to do differently.

The phrase means five different things depending on who's saying it. A lux number cuts through the ambiguity. Here's the range that actually matters.
