One app that grows with what you grow — and tells you what's next.
Built on published agronomy. Lives on your device. Scales from a few raised beds to a working farmstead with bees, chickens, and goats.
From the first seed to what ends up on the table — growing, animals, land and water, what to watch for, and what to do with the harvest. Plus built-in reference guides: a plant catalog, poultry and livestock breed guides, a mushroom guide, and sourced ways to use what you pick. Every entry sourced, and every one works offline.
Built for the path from your first tomato bed to a full kitchen garden.
Bees, hens, ducks, goats — whatever you raise, in one logbook.
The infrastructure layer — your yard, your beds, your irrigation lines.
What's headed your way, before it hits.
What happens after the picking — keeping it, using it, and knowing what's in it.
The business side of the homestead — money, records, and what's next.
Local-first, multi-device, never locked in.
Start from 1,400+ plants with zone, sun and days-to-maturity, so you pick from a rich list instead of typing from scratch. Frost-relative scheduling, spring and fall windows, variety-level tracking, performance ratings, and per-variety notes help you grow what fits your garden and table.
Grow gourmet mushrooms on logs, blocks, or beds: ten species from oyster and shiitake to lion's mane and chestnut. Track inoculation, spawn run, and fruiting, and log each flush's yield right alongside your plants.
Suggest a plot recommends crop-family-safe picks for each open bed and flags picks that are already too late for the season. Nursery tracks anything started indoors or by cutting until it's ready to go in the ground. And once a fast-turnover crop like lettuce or beans is in, the engine schedules the next sowing so your harvest never gaps out.
Track every bin with its own method (tumbler, hot pile, standard, cold, vermicompost). Turn-and-moisture reminders fire on the right cadence; hot piles get a 130–160°F temperature tracker.
Point your camera in-app and PlantNet returns a species match. Or sync cultivated iNaturalist observations as candidate plantings ready to confirm.
Enter your extension lab's NPK + pH and GardenKnowm produces crop-specific, bed-aware recommendations using NC State, Cornell & Penn State amendment math.
Langstroth, top-bar, Warré, Flow, each tracked in its own equipment (box stack, frame or bar sizes). Per-queen records through supersedure, mite counts and treatments, honey harvests with brix and moisture. Winter readiness scored against a stores target for your latitude, plus printable QR hive tags.
Chickens, ducks, geese, quail, turkeys, guinea fowl, backed by a sourced breed guide to help you pick the right birds. Log eggs by individual bird (for show breeders) or whole flock (the realistic default). Reminders adapt to how often you log.
Goats, sheep, pigs, cattle, rabbits, with a sourced breed guide spanning all five species and the right registration fields per animal: scrapie tags for sheep, ear notches for pigs, ARBA numbers for rabbits. Bulk-add a litter when one record per animal isn't worth it.
Draw plots on a satellite map, anchor them to GPS, attach photos and soil tests to the specific bed they came from. The fertilizer advisor's recs go bed-aware, not yard-wide.
Daily ET₀ deficit + soil-aware scaling + cycle-and-soak — recommends frequency and duration. Per-zone schedules, FAO-56 crop coefficients differentiate by what's growing where.
EZ-FLO, Mazzei, Dosatron, Add-It. Projects when each tank will empty from your dilution ratio and flow rate, then calibrates against the cups you actually pour at refill.
A heads-up before you plant, not after: if a bed grew the same crop family recently enough that a rest period is still advised — nightshades, brassicas, cucurbits, alliums and more — you'll get warned ahead of your typical planting time, and again if you assign the plot anyway. Covers 143 vegetable, grain, and cover-crop varieties, sourced to Cornell Cooperative Extension.
Gardener-relevant NWS active alerts at your location with a synthesized “what to do” line. Cold-front bundle fires one reminder listing every vulnerable plant when sub-35°F is forecast.
Your county's iNaturalist sightings cross-referenced against the crops you've planted. Photo a leaf and PlantNet's disease endpoint identifies it; the catalog draws on NC State and Cornell Vegetable MD.
Extension-validated biocontrols (Bt, spinosad, beneficial nematodes), per-legume Rhizobium inoculants, and biofungicides. Every entry cites a UC IPM / NC State / Cornell / EPA source.
Cross-references your planted crops with iNaturalist observations to score your yard 0–100 and rank you against your county. Native species, trophic levels, and pollinator visits are weighted.
Sourced ways to use what you grew, right on the plant, hive and flock screens: canning, pickling, fermenting, freezing, drying and sweet spreads across 238 crops, plus honey, beeswax and eggs. From the National Center for Home Food Preservation and university extension services.
Per-100g macros and micronutrients for 178+ crops from USDA SR Legacy 2018, on the plant screen next to what you're growing. Calories, protein, fiber, vitamin C, folate, potassium, iron and more — so “what should I plant more of” can be answered by what your table actually needs.
Season in Review pulls the year together: what you planted, what performed, and what it yielded. Plus crop-performance intelligence, egg productivity, honey yield, the Detailed Apiary Report (foraging days, drought, year-over-year, and a by-yard comparison for multi-yard operations), and livestock production reports — each exportable as a PDF.
Log sales and expenses in a couple of taps. Tag each entry by area — bees, poultry, plants, and livestock — to see what's actually paying for itself. Planning something new? Plug in the cost and expected savings for a months-to-breakeven estimate, then track real progress toward paying for itself as it happens. Export a PDF report whenever you need one.
Weight-history charts, medication and treatment logs with withdrawal tracking, and gestation and incubation due-date countdowns for livestock and poultry. Add pedigree family trees, breeding-stock genetics comparison, and PDF reports you can print or share.
One prioritized “This week” view pulls together irrigation, frost, succession sowing, pest alerts, and overdue tasks. Real Android push notifications fire for anything time-critical, and per-rule toggles let you turn off what you don't want to hear about.

iOS is on the roadmap. No social network, no commercial farm tooling — we know what we're not.

GardenKnowm runs on Android (phone and tablet) and Windows desktop — same codebase, same local database. The Windows desktop app and encrypted LAN sync between your devices come with the one-time desktop bundle.
iOS and macOS are on the roadmap. No timeline to share yet.
The app works anywhere — your plant journal, soil tests, hive inspections, and harvest records are fully local and need no internet. A few features are geography-limited by the underlying data sources:
Marketing and App Store availability is focused on the US, Canada, UK, and Western Europe for now. The app works fine elsewhere — it just isn't localised yet.
The records you create — plants, hives, flocks, photos, notes, your location — live in a SQLite database on your device. We run no servers and no accounts, so we never receive them. There is nothing of yours on our end to breach.
The free version shows ads through Google AdMob, and like all mobile ads that SDK collects ad-related data — an advertising identifier, IP address, device type, and ad taps — to serve and measure them. That's the one thing that leaves your device, and the one-time GardenKnowm Pro purchase removes the ads and that data collection along with them.
The optional features that reach the internet — weather station polling, AI assistant, plant identification — all use your API keys, talking directly from your device to the provider. We are never in the middle of those calls.
You can export everything to a local JSON file at any time from Settings → Export. Full details are in our privacy policy.
The core app is fully offline. Journals, planting records, hive inspections, harvest logs, soil tests, and reminders all work without a connection.
These features require internet when you use them:
Everything else works fine offline.
No. Knowm is a nanoelectronics company building neuromorphic processors. We share part of a word, nothing else.
The name GardenKnowm is a play on gnome — as in garden gnome — and the idea of actually knowing your land: its soil, its frost dates, its biodiversity.
Leave your email and we'll let you know the moment the iPhone/iPad and Mac version is ready.
