About this app
GroundKit — Soil-Driven Planner for Regenerative Gardeners Stop guessing what your beds need. Read your soil test, calculate exact NPK amendments, plan plantings around your frost dates, and journal what actually grew — all in one app, built by gardeners tired of juggling spreadsheets and bookmarks. — WHAT YOU CAN DO — NPK CALCULATOR Enter your soil-test values (or scan a report with your camera) to see exactly what your bed needs. Free users get clear N, P, and K readings. Premium unlocks exact lbs/acre values, percent-of-target progress, and full amendment math. ORGANIC AMENDMENT LIBRARY Curated organic-only amendments — blood meal, fish emulsion, kelp, rock phosphate, greensand, and more — with editable NPK percentages, bed-sized application math, and pricing. No synthetics, ever. GARDEN PLANNER Lay out beds visually. Drop crops by name, set seed-start and transplant dates, and watch your planting calendar fill in automatically. Plan companion planting, succession sowing, and rotations. SEED PLANNER Pick your USDA zone (or auto-detect by ZIP) and see seeds matched to your nutrient profile, soil pH, and current month. Filter by category, pin favorites, and pull them straight into your garden plan. PLANTING CALENDAR (Premium) Frost-date-anchored events for every pinned seed — start indoors, direct sow, transplant — auto-generated from your last frost date and customizable per crop. HARVEST & GROWTH JOURNAL (Premium) Log harvests, growth notes, and bed health through the season. Attach photos so you remember what worked. LOCAL SUPPLIER SEARCH Find seed companies, organic fertilizer retailers, and nurseries near you — searchable by ZIP or name, with directions and one-tap calling. COMPOST CALCULATOR Sized to your bed and soil condition (new, established, depleted) — finished-compost yield, application depth, and first-year N, P, and K availability. — PREMIUM MEMBERSHIP — Unlock the full power of every tool: exact amendment amounts and shopping list, full amendment library with custom entries, unlimited garden beds, full planting calendar with auto-suggestions, unlimited seed pinning, and the harvest journal. Lifetime — $4.99 (one-time purchase, no renewal) Subscriptions renew automatically until cancelled in App Store settings. — BUILT FOR REAL GARDENERS — Regenerative-first. No synthetic recommendations. No ads. No locked-in cloud sync — your soil tests, beds, and journal stay on your phone.
