Sowclock

Planting dates worked out from your own frost dates, with a year ribbon

Sowclock turns two dates you type, your average last spring frost and your first fall frost, into a planting calendar for your garden. It does not ask for your location and has no account: you decide which dates it works from.

How it works Enter the month and day of each frost date and pick the year to plan. Sowclock then works out, for every crop in its table, when to start seeds indoors, when to transplant, when to sow outdoors, when the harvest window falls, and the last sowing date that still lets the crop mature before fall frost.

What you get - This week: the crops to start indoors, transplant or sow in the next seven days, plus a last-call list for crops whose final sowing date is close. Step forward or back week by week, or jump to the next busy week. - Year ribbon: one row per crop with four thin bars (start indoors, transplant, sow outdoors, harvest), frost-risk months shaded blue and a line for today. - Built-in crop table: 44 common vegetables and herbs with rounded, cautious ranges for weeks before or after the last frost and for days to maturity. It is a general guide, and the in-app Guide explains where the figures come from. - Edit anything: change any value of any crop, restore the original values later, or add up to 40 crops of your own. - Season fit check: each crop is flagged when its earliest planting date leaves too little time before fall frost, with the number of days to spare or short. - Fall buffer: the last sowing date is the first fall frost minus the longest days to maturity minus a buffer you set (14 days to start with). - My plan: choose your crops, tick off each step as you do it, and share the plan as plain text. - Season length: see how many days lie between your two frost dates.

Good to know Dates are guidance, not a promise. Varieties, soil, shelter and weather all matter, so check your seed packet and local gardening advice where they differ. Frost dates are averages, and frost can come earlier or later.

Sowclock works fully offline and asks for no permissions. Your dates, edits and plan stay on your phone and nowhere else; a reset in Settings wipes them.
