Most plants die in the wrong light. Plant Compass uses real solar geometry for your exact address to take the guesswork out of placement.
Maps your real home
Pro traces a satellite outline of your house and works out which way every wall and window faces.
Works anywhere
Lite uses your phone's compass so you get instant plant ratings without any setup, perfect for apartment hunting or nursery shopping.
Tracks the sun
We compute the sun's path for your latitude, from sunrise to sunset and summer to winter, for real hours of direct light.
Matches plants to light
Every window and direction gets a light rating. We rank which of your plants will thrive, scorch, or stretch there.
Never forget to water
Pro's per-plant watering reminders are tuned to each plant's needs, so nothing dries out or drowns.
Identify by photo
Don't know what you've got? Both apps let you snap a photo to identify a plant on the spot using Pl@ntNet's recognition.
Track the sun, not your luck.
That gorgeous golden hour? We know exactly when it hits each window, how long it lasts, and how it shifts from June to December, so you place plants for the season they struggle in, not just their best one.
Every plant, its perfect window.

Frequently asked
What's the difference between Pro and Lite?
Plant Compass Pro maps your actual home using satellite imagery, places your windows on the map, and gives you exact hours of direct sun for each one: summer, equinox, and winter. Lite is a quick-check compass: just point your phone at a wall and instantly see which plants thrive, cope, or struggle in that direction. No mapping needed.
Is Plant Compass free?
Both apps are free to download. Pro lets you add up to three plants at no cost; Plant Compass Pro ($2.99/month) unlocks unlimited plants. Lite is free with a one-time in-app purchase to unlock your full plant collection.
How accurate is the sun data?
We use astronomical solar-position math for your exact latitude and longitude, accounting for the season. In Pro you can also mark what's outside each window — a tree, an overhang, a building — so the estimate reflects your real surroundings.
Do you store my address?
Your home and plants stay on your device. In Pro, your data syncs to your private account so it follows you across devices. We never sell your data. See our Privacy Policy.
Do I need an account?
Lite works without an account. Pro offers sign-in via email link so your home and plants sync across every device you use.
What if my house isn't on the map?
No problem. Drop a pin and tap your roof, or just place windows by compass direction. The sun math works either way.
