Frequently asked questions

Plant Compass Pro maps your actual home from satellite imagery, places your windows on the map, and gives exact hours of direct sun per window across every season, with fit ratings from perfect to too bright or too dim. Lite is a quick-check compass: point your phone at any wall and instantly see which plants thrive, cope, or should be avoided in that direction. No mapping required.

Both apps are free to download. Pro lets you add up to three plants at no cost; unlimited plants unlock at $2.99/month or $19.99/year. Lite is free to use with a sample plant and the full compass; a single one-time in-app purchase unlocks your whole plant collection, with no subscription ever.

Plant Compass is an iPhone app, and it also runs on iPad in iPhone-compatibility mode. There's a web version of Pro you can use in a browser too. An Android version isn't available yet.

Yes. The sun calculations use astronomical solar-position math for any latitude and longitude on Earth, so it works worldwide and in both hemispheres.

We compute the sun's real path for your exact latitude and longitude, accounting for the season, from sunrise to sunset. In Pro you can also mark what's outside each window (a tree, an overhang, a building, or open sky) so the estimate reflects your real surroundings.

Both apps let you snap or upload a photo and identify the plant using Pl@ntNet's recognition. The match is added to your collection along with its light needs, so you can place it right away. No API key needed.

Window scan is a Pro feature: point your camera at a windowsill or shelf and it detects every plant in view at once, then matches each one to your windows. It's the fastest way to add a whole collection.

Pro includes per-plant watering reminders tuned to each plant's needs, so nothing dries out or gets overwatered. You can adjust the interval for any plant.

Lite works fully without an account. Pro offers an optional sign-in via email link so your home and plants sync across every device you use. You can start as a guest and create an account later.

Your home and plants stay on your device. In Pro, your data syncs to your own private account so it follows you across devices. Address lookup and sun positions are computed on your device, and we never sell your data. See our Privacy Policy.

Your purchases and subscription are tied to your account, so signing into both apps with the same email recognizes what you own. Plant collections are currently stored separately in each app.

No problem. Drop a pin and tap your roof outline, or just place windows by compass direction. The sun math works either way.

Pro is free with up to three plants. Unlimited plants, window scan, and photo ID unlock with a subscription at $2.99/month or $19.99/year.

The free version of Lite is the live sunlight compass with a sample plant. A single one-time purchase unlocks adding all your own plants, searching the full catalog, and identifying plants by photo. It's a one-time purchase, not a subscription, and you can restore it free on a new device with the same Apple ID.

Subscriptions are managed through Apple. Open the Settings app on your iPhone, tap your name, then Subscriptions, find Plant Compass, and make your change there.

Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com, sign in, find the purchase, and request a refund. If something went wrong on our end, contact us and we'll help.
