Seed starting schedule · iPhone & iPad · Pay once
The hardest part of growing from seed is the math: count six weeks back from a frost date, for every veggie in the bed, twice a year. Type your last spring frost and your first fall frost once, and Sow does the counting. It works offline, in any country, and it knows which of your seed packets are past it.

34-second tour
Two frost dates, the week-by-week plan with its math, and the seed box. The captions are on screen, and the sound is one tap away.
The seed packet says: start six weeks before last frost. Then you count backwards, for every crop, twice a year.
This is Sow. Type your last spring frost, and your first fall frost. Two dates. That's the whole setup.
Every crop becomes a week-by-week plan, with the math shown. The seed box checks each packet: good, test, or replace.
South of the equator? Your dates. Your season. Pay once. Works offline. No account.
Sow. Two dates in, a whole season out.
Seed starting, scheduled
Sow does not look up a zone or guess your climate. It counts from the two dates you type, so the schedule is as right as your own knowledge of your own beds.
Two dates
Your county extension office publishes your frost dates, and so does the best gardener on your street. Spin two month and day wheels and you are done. Any month is allowed, so the dates work north or south of the equator, and in any country.
No ZIP lookup, no zone map, no hard-coded zone 7. The dates you type are the dates Sow uses.
The math, shown
Each crop becomes a week-by-week checklist: start indoors, harden off, transplant, direct sow. Every line says how it was counted, like "6 wks before last frost, week of Mar 16", so you can see it and disagree with it.
Nudge any task up to two weeks for your microclimate. Offsets follow common extension-office conventions, and your seed packet outranks any chart.
The seed box
Log every packet with the year you bought or saved it. Sow gives each one a viability verdict: still good, test a few on a damp towel first, or replace. Stop sowing dead seed. Stop rebuying live seed.
Each plan shows whether you already have seed for it, so the January order writes itself.
Verdicts are estimates from typical seed-storage tables. Custom crops show "no data" until you add their germination years.
Reminders that arrive on time
Optional local reminders land on the Monday morning of the week a task is due, from your phone, with no server involved.
Behind? Missed tasks slide into a quiet Catch up list. It never goes red and it never nags. A later sowing is a shorter harvest, not an emergency.
Fall crops, too
Spring tasks count back from your last spring frost. Fall crops like garlic and spinach count back from your first fall frost, using the second date you typed.
Succession in one tap: "Lettuce, round two" copies a plan two weeks later. And when next year comes, Plan next year copies your whole crop list into a fresh season.
66 crops, plus your own
Sixty-six vegetable, herb and flower crops come built in. Add a custom crop with your own timings and germination years, and it gets the same plan and the same seed box as everything else.
Grow ground cherries, a local pepper or something your neighbor swapped you? It is a full crop with its own plan, not a note.
Your garden stays yours
Sow does not collect, store or transmit any data. Your frost dates, plans and seed box live on your phone, and the app makes no network connections of any kind. Export your plan and seed inventory as a CSV whenever you like, and send it wherever you choose.
Accessibility
Sow supports these App Store Accessibility Nutrition Labels for the common tasks: setting frost dates, adding crops, reading and checking off the weekly plan, adjusting a task, and adding and reviewing seed packets.
One price. Every future update included. No subscription, no account, no paywalled vegetables.
$6.99
Your county extension office publishes them, and so does the best gardener on your street. Type your last spring frost and, if you want fall crops, your first fall frost. You can add the fall date later.
Yes. Sow has no ZIP lookup and no zone map, and the frost date wheels accept any month and day. A gardener in Brisbane types a last frost in the austral spring and Sow counts from that, exactly as it would for a gardener in Ohio. Schedules count from the dates you enter.
Sow counts back from the two dates you type, so use the dates your growing season opens and closes. The offsets follow common extension-office conventions, which were written for frost climates, so lean on your own packet and your own experience and use the adjust control.
Each crop has a typical number of good years when seed is stored cool and dry. Sow compares that with the year on your packet and shows GOOD, TEST or REPLACE. These are estimates from typical storage tables, not guarantees, so a damp-towel test is the real answer for borderline packets.
No account and no sync. Everything lives on your device, and the app makes no network connections. Export your plan and seed inventory as a CSV whenever you want a copy.
No. It is $6.99 once, with no in-app purchases and every future update included.
An iPhone or iPad running iOS 16 or later. Buy it once and it is yours on every device signed in with your Apple Account.
