Frequently asked questions
How do I log a watering?
Open the plant and tap I've watered, tick it off in the list on your shelf, use the button on a Home Screen widget, or tap Watered ✓ on the reminder. Your plant jumps for joy either way.
What do the faces mean?
A Greenling's face shows how it is doing. It is thriving right after a drink, happy most of the time, thirsty when watering day comes, and unhappy when it has waited too long.
Only unhappy resets your streak. Watering cheers them up any time. For a quick overview, open Settings and choose How Greenlings feel.
How does the streak work?
Your streak counts the weeks in a row in which none of your Greenlings was unhappy. Weeks roll from the day your streak started, not Monday to Sunday. Thirsty is fine.
At milestones all your Greenlings throw a party. Each plant also keeps its own count: open it to see how long it has been happy (“Happy for”). Tap the badge on your shelf to see your streak.
How often should I water?
You decide. When you add a plant, pick the interval you water it at now. You can change it any time by editing the plant. Greenlings gives no care advice; it simply follows the schedule you set.
My reminders don't arrive.
Check that notifications are on for Greenlings in the iPhone Settings app, and pick your reminder time in Greenlings' own Settings.
Reminders are planned two weeks ahead. If you haven't opened Greenlings or logged a watering in a while, open the app once to plan the next ones.
I logged a watering by mistake.
Open the plant, tap the ••• menu and choose Undo last watering. It works for every way of logging, including widgets and stickers.
My plant isn't in the list.
Greenlings has eight Greenlings for now: monstera, snake plant, cactus, pothos, peace lily, echeveria, rubber plant and ZZ plant. Choose the Greenling you like best for it and give it any name. More Greenlings are on the way.
Is Greenlings free?
Yes. Greenlings is free to download and use, with no account, no ads and no in-app purchases.
Which iPhones are supported?
Any iPhone with iOS 18 or later.
I'm getting a new iPhone. Will my plants come along?
Greenlings keeps your plants on your iPhone, so they move with an iCloud backup or when you transfer your data to the new iPhone. Paired stickers keep working; their IDs stay the same.
How do I delete a plant or all my data?
Open the plant, tap the ••• menu and choose Delete plant. To remove everything, delete the app. See the privacy policy for what is stored.
Extras: NFC stickers
Completely optional. Greenlings works fine without them.
Do I need NFC stickers?
No. Stickers are an extra for people who like gadgets: hold your iPhone to the pot and the watering is logged. Everything else works without them.
Which NFC stickers work?
Almost any small NFC sticker, such as the common NTAG213, NTAG215 or NTAG216 stickers. Greenlings only reads the sticker's unique ID, so it does not need to be empty or set up in any way, and nothing is written to it.
Use one sticker per pot, on a spot you can reach easily with the top of your iPhone.
How do I set up tap-to-water?
Open the plant, tap the ••• menu and choose Set up tap-to-water. Greenlings walks you through it: pair the sticker, add the Shortcuts automation, then try it. Adding a new plant? Tap Got an NFC sticker? Pair it on the last step.
Once a plant has a sticker, the Scan button appears on your shelf.
How do I log watering with one tap, without opening the app?
A Shortcuts automation, set up once per sticker, logs the watering when you tap the pot. The steps differ between iOS 18 to 26 and iOS 27, so they have their own page.
