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.
Eighteen tools, organized into five jobs. Tap a category — the breadth is there when you need it, out of the way when you don't.
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.
Local-first, multi-device, never locked in.
Year-round plans with frost-relative scheduling, spring and fall windows for cool-season crops, variety-level tracking, and year-over-year performance ratings.
Enter your extension lab's NPK + pH and GardenKnowm produces crop-specific, bed-aware recommendations using NC State, Cornell & Penn State amendment math.
For fast-turnover crops — lettuce, radishes, beans, beets, cilantro — 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.
Langstroth, top-bar, Warré, Flow. Per-queen records through supersedure, mite counts and treatments, honey harvests with brix, moisture, and color. Bundle inspection reminders across yards.
Chickens, ducks, geese, quail, turkeys, guinea fowl. 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 the right registration fields per species: 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.
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.
With the desktop bundle, pair phone, tablet, and desktop on the same Wi-Fi and edits flow both ways automatically — encrypted, no account, no cloud. Pair once via QR, sync forever.
Generate free-tier keys for Groq, OpenAI, Ambient Weather, Perenual, Trefle, PlantNet. Your phone talks to those services directly. We never see the traffic.
Daily auto-export to JSON + CSV. Switch phones, switch apps, switch hobbies — your homestead history goes with you. No premium tier required to leave.
Irrigation, fertilizer, pest, and planting advice draw on established frameworks — not internal hunches. Tap a source to see what it powers.
Use the full core app free with ads. Go Pro once to remove them and unlock breeding-stock comparison and PDF reports; add the desktop bundle for the Windows app and multi-device sync. Your data always stays on your device.
The full core app on your phone and tablet — plants, hives, flock and livestock records, reminders, weather, and your data export — free, supported by occasional, unobtrusive in-app ads.
Everything in Free with no ads, plus breeding-stock comparison & genetics analysis and PDF inspection reports. Pay once — no subscription, ever.
Pro across phone and tablet plus the Windows desktop app, all kept in sync over encrypted LAN. Multi-device sync comes with the desktop bundle.
Final pricing TBD. 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.
