Seasonal watering
Less water in winter, without thinking about it
More houseplants die in February from kindness than in August from neglect. This is the feature that fixes that.
A monstera wants water roughly weekly in summer. In December, in a northern winter, the same plant in the same pot might want it every ten or twelve days, because it is barely growing. Almost every houseplant death by overwatering happens in the months when the owner kept doing exactly what worked in June. A fixed repeating reminder cannot help with this, and editing forty of them twice a year is not something anyone actually does.
How it works
Driven by daylight, not by a date
The seasonal adjustment is computed from the actual daylight at your location rather than from a calendar month, so the same plant behaves differently in Stockholm and in Lisbon, which is correct, because it does.
Per species, not one global rule
Plants whose watering is driven by growth, the aroids, the ficus, the succulents, stretch through winter. Plants whose need is driven by humidity rather than light, like calatheas and ferns, barely change. The catalogue records which is which.
Counted from when you actually watered
The next date is calculated from the moment you logged the task, not from a fixed cadence. Water two days early before a trip and everything downstream shifts with it, which is the single biggest practical difference from a repeating reminder.
Weather nudges for the exceptions
A heatwave or an incoming frost triggers a heads-up, because those are the two events that break a schedule no matter how good it is.
The details that matter
How the counters work
Every task is a pure function of the interval, the last completion and your home timezone. All timestamps are stored in UTC and day boundaries are computed in the profile's home timezone, which means flying from London to San Francisco does not make a counter jump a day. It is more care than a watering app strictly needs, and it is why the numbers stay right.
Overdue is shown calmly
An overdue task is coloured a muted coral rather than an alarm red, and the app does not escalate, badge or nag. A plant that is two days late is not an emergency, and treating it like one is how people end up ignoring the app entirely.
One digest, not forty notifications
Reminders are grouped into a single gentle daily digest that respects quiet hours, rather than firing one notification per plant. Forty plants would otherwise mean forty pings.
You can always override it
Every interval is editable per plant and per task. The catalogue is a starting point informed by the species, not a rule. If your flat is unusually dry or your pot is unusually small, change it and the app will use your number.
What this costs
Free at every tier. Seasonal adjustment, weather nudges and the daily digest all work on the free five-profile plan.
Questions, answered
How often should I water houseplants in winter?
Less often, and how much less depends on the plant and on how far north you live. As a rough guide, growth-driven plants like monstera, pothos and most succulents can stretch by around half again through the darkest months. Humidity-driven plants like calatheas and ferns change much less. The app calculates it per species from your actual daylight rather than asking you to guess.
What if I water early or late?
Log it when you do it and the schedule recalculates from that point. There is no penalty, no streak to break and no red mark. The counter simply moves.
Does it use my location?
It uses coarse location for the daylight calculation and the weather nudges. That stays on the device and is not linked to any identity, because there is no account to link it to.
Can I turn the seasonal adjustment off?
Yes. Set a plain interval on any task and it will be used exactly as written.
