Pot size adjusts the gap.
A 4″ pot dries faster than a 12″ pot. Tazart shortens the reminder gap for small pots and extends it for large ones, automatically.
Water reminder app · Free
Water reminders that follow your plants. Not a calendar.
Tazart is a free water reminder app for iPhone built specifically for plants. Unlike generic water tracker apps that just ping you every 4 hours, Tazart adapts each plant's watering schedule to its species, pot size, room light, your local weather, and the time of year — so reminders fire when the plant actually needs water, not on a calendar. Apple Watch app and Lock Screen widgets are included free. Tap once on your wrist or Lock Screen to mark a plant as watered.
5 ways Tazart adapts
Plant-aware. Not a generic timer.
Five factors per plant — every reminder fires when the plant actually needs water.
Room light shifts the schedule.
South-facing windows = faster soil dry-out = more frequent water. North-facing = slower. Tazart asks for light direction when you save a plant.
Weather adjusts ±3 days.
Heat wave coming? Tazart pulls reminders forward. Cold rainy week? It pushes them back. Pulls live forecast from your location.
Season changes the baseline.
Most houseplants need ~30% less water in winter than summer. Tazart automatically scales reminders by season — no manual tweaks required.
Species-specific defaults.
Snake plants every 14 days. Pothos every 7. Calatheas when the top inch is dry. Tazart starts each new plant from its species's actual care profile.
Questions, answered
Water reminder FAQ.
How is this different from a generic water reminder app?
A generic water tracker pings you every X hours regardless of context. Tazart calculates each plant's actual water need from species + pot + light + weather + season, so you don't overwater the snake plant while underwatering the calathea.
Does it work on Apple Watch?
Yes. The Apple Watch app shows what's due today (water, fertilize, repot). Tap any plant to mark it cared-for from your wrist. Free, no separate purchase.
Does it work on the Lock Screen?
Yes. Lock Screen widgets show today's plant tasks at a glance.
Will it spam me with notifications?
No. Tazart batches reminders into one daily summary by default — "3 plants need water today" — at the time you choose. Per-plant alerts are optional and off by default.
Does it know my local weather?
Tazart pulls hourly forecast data from Apple WeatherKit (the same source as the iOS Weather app), tied to your iPhone's location. No third-party weather API, no extra signup.
What if I'm on vacation?
Welcome Back Recovery catches up your plants after a trip without flooding you with overdue reminders. Tell Tazart when you're leaving and returning, and it suspends + reschedules everything intelligently.
Can I set reminders for fertilizing and repotting too?
Yes. Tazart handles watering, fertilizing, repotting, pruning, rotating, and misting — each on its own schedule per plant. Care Sessions let you batch all due tasks into a single tap.
Is the water reminder really free?
Yes. Watering reminders, weather adaptation, Apple Watch app, Lock Screen widgets, and Care Sessions are all free with no daily cap and no subscription.
