Built for the shoebox of half-used seed packets in your kitchen drawer. Know what you own before you buy more, and sow the old ones before they quietly give up.

What it does

Your whole seed stash, in one tidy list.

No spreadsheet, no garden planner, no login. Just the seeds you have on hand, sorted however you like, with a gentle flag on the ones getting old.

Feature 01

Log a packet in about ten seconds

Plant, variety, the year printed on the packet, and a rough sense of how much is left. That is the whole form. Add it now, edit it later, or mark a packet used up when you sow the last of it.

  • Four fields, no fuss: plant, variety, year, amount left
  • Mark a packet used up without losing its record
  • Everything saves the moment you tap, right on the phone

Feature 02

It tells you what to sow first

Most seeds lose their pep after a few years. Seed Box does the math on the packet year and quietly flags the ones getting old, so you reach for the 2021 lettuce before it stops sprouting on you.

  • A gentle use-soon nudge based on the packet year, not guesswork
  • Fresh, use soon, and getting old badges you can read at a glance
  • A running count of how many packets are starting to fade

Feature 03

Sort, filter, and find in a tap

Search by plant or variety, filter down to what is in the box or what is getting old, and sort by name, packet age, or how little is left. The whole stash, however you want to look at it that day.

  • Filter by in the box, fresh, use soon, or used up
  • Sort by name, oldest packets, or least left first
  • Warm, hand-drawn look with big tap targets and real contrast

How it works

From drawer chaos to a clean list in minutes

No account, no app store, no setup. Add it once and it opens full screen, ready whenever you sit down to sort seeds.

1

Add to the home screen

Open it in Safari once, tap Share, then Add to Home Screen. After that it works offline, full screen, like a little native app.

2

Empty the seed drawer

Go through your packets and log each one: plant, variety, the year printed on it, and roughly how much is left.

3

Sow the old ones first

Let the use-soon flags point you at the packets losing vigor, and plant those before you buy a single new seed.

Under the hood

One small file. Local storage only. Nothing leaves the phone.

Seed Box is a single HTML file you save to your home screen. The whole thing, art and all, is baked right in, so once it loads it never needs the internet again.

There is no server and no account, so there is nothing to breach and nothing to track. Your seed list lives in this one device's local storage and nowhere else, which means it keeps working on an airplane or in a cellar with no signal, and also that clearing your browser data clears your seeds. It is a personal inventory, not a synced cloud account, and it is honest about that. The contrast and tap targets are sized for muddy garden hands and tired eyes, the motion softens to a still state when a phone has Reduce Motion turned on, and the only thing it ever asks of you is the year printed on the packet. A small, honest app, built the way I think small apps should be: useful first, quiet always, and content to keep to itself.
