Riego Patio: A Plant-Watering Tracker Built for a Two-Week Stand-In
When your grandmother is in the hospital and her fern is counting on you, a generic reminder app won't cut it. Here's the tool one grandson built instead.

For two weeks, Diego had one job: keep his grandmother's patio plants alive while she recovered from surgery. There were eleven of them, each with its own rhythm she'd taught him in a rushed ten-minute handoff. The fern every two days. The cactus every five. The geraniums whenever the soil felt dry. He wrote it all on a sticky note, lost the sticky note on day three, and spent the rest of that week anxiously guessing.
So he described the problem to Leanfinit in a single sentence, and by that evening he had Riego Patio, a focused little app that does exactly one thing well: tells you, right now, which plants need water today, and lets you check them off one by one.
Live demo
The screen you see when you open it matters more than anything else
Most habit apps make you navigate to today's tasks. Riego Patio skips that entirely. The moment you open it, the plants that need water are already at the top, sorted by urgency, with overdue ones called out visually so they're impossible to miss. The fern, which Diego kept skipping, now floats to the top with a subtle overdue indicator whenever he's a day late.
This sounds small, but it changes how the app feels to use. Diego opens it every evening before dinner, checks off whatever's thirsty, and closes it. The whole ritual takes about forty seconds. That's the point. He's not a gardener managing a project, he's a grandson trying not to kill something his grandmother loves.

Each plant runs on its own clock
Generic plant apps usually offer a 'water weekly' setting and call it done. That doesn't work for a patio where every plant has its own idiosyncratic schedule rooted in years of observation. The fern wants water every two days. The bird of paradise goes five. The small succulents near the wall can go a week.
In Riego Patio, each plant carries its own interval. When you mark it watered with a single tap, the app calculates that plant's next due date from that exact moment, not from some fixed calendar day. So if Diego waters the geraniums a day late on Tuesday instead of Monday, the app recalculates from Tuesday and doesn't pile on extra urgency the next cycle. It adapts to real life rather than punishing imperfection.
Alongside the schedule, each plant entry holds the grandmother's specific care notes. Not generic advice pulled from the internet, but her actual instructions. 'Water at the base, not the leaves.' 'The fern likes the shady side.' 'Don't overdo the bird of paradise.' These live right where Diego needs them, attached to the plant, visible when he's standing there with a watering can.
Try the app in the demo below
The live version embedded here is the real thing. You can open it, tap through the plants, mark one watered, and watch the schedule update. The home screen will show you the overdue-first sort, and you can tap into any plant to see its notes and history.
Notice how the overdue indicator works: it's not a subtle badge you might miss, it's a clear visual shift that makes the neglected plant feel urgent without being annoying. And notice how one tap is genuinely all it takes to mark something done. There's no confirmation dialog, no 'are you sure', just an immediate satisfying check.
A two-week history that offers reassurance, not data
One anxiety Diego hadn't anticipated was the creeping doubt: am I actually doing this right? He'd marked everything off, but had he missed something? Was the fern going to look wilted when his grandmother came home?
The history view in Riego Patio is built for that feeling. It's not a spreadsheet or a heatmap. It's a simple two-week log showing when each plant was last watered, easy enough to scan in five seconds. Not so detailed that it becomes a chore to interpret, just enough to confirm that yes, you've been keeping up. For a non-gardener carrying someone else's responsibility, that quiet reassurance matters.
No account, no internet, no setup friction
This app was built for one phone, one person, one two-week window. It runs entirely offline. There's no login screen, no email confirmation, no sync to worry about. You open it, you enter your plants once (takes about three minutes for a standard patio), and then you're in the daily rhythm.
That zero-friction setup is a deliberate choice. A plant-watering tool that requires an account and a cloud subscription would feel absurd for a temporary, personal task. Riego Patio is closer in spirit to a well-designed notebook than to a subscription service. It just happens to live on your phone and remember things for you.

Have a small problem that deserves a real tool?
Riego Patio started as one sentence: 'I need to track which of my grandmother's plants need water while she's in the hospital.' If you have a specific problem you keep solving badly with sticky notes or calendar reminders, describe it to Leanfinit and see what gets built.
