What it does

Simple tools that make a real difference.

Crop planner

Build a season plan matched to your land, method and budget — with costs and returns laid out before you spend.

Weather & alerts

A seven-day local forecast that tells you what to do — when to top-dress, irrigate, or act on a pest warning.

Satellite monitoring

Your registered fields are checked from space each week, flagging stress early — before it shows on the ground.

Input verification

Scan a QR code or search the verified database to confirm seed and fertiliser are genuine before you buy.

Market prices

See today's farmgate and market prices across nearby markets, with trends and target-price alerts.

Expert advice

Send a photo or voice note of a problem and a trained agronomist replies with a real answer, in Kiswahili.

Sell your harvest

List your crop, compare written offers from verified buyers, and get paid digitally before it leaves the farm.

Crop insurance

Affordable index-based cover that pays out automatically to your mobile money if the rains fail — no claim forms.

Finance & records

Every season you log builds a financial track record that helps you qualify for input credit and equipment finance.

Group & co-op tools

Shared accounts let groups and AMCOS order inputs and sell together for stronger market leverage.

Crop planner

Plan the whole season before you spend a shilling.

Enter your location, land size and crop, then choose how you want to farm it. The app builds a complete, personalised plan so you can see exactly what each approach will cost — and what a realistic return looks like — up front.

Rainfed

Rainfed production

Built around your local rainfall calendar, showing the critical windows where rain timing matters most.

Irrigated

Irrigated production

Drip or solar-pump irrigation for steadier yields, longer growing windows and multiple seasons on one plot.

Direct seeding

Direct seeding

Seed straight into prepared soil — faster and lower-labour, ideal for maize, sunflower and legumes.

From a seedbed

Transplanting

Seedlings raised separately for stronger establishment — suited to tomato, watermelon and cabbage.

Costed week by week

Every plan, with the numbers behind it.

For whichever method you choose, the app lays out a full schedule with costs broken down by phase — so you know not just the total, but when each expense lands.

  • Land preparation, seed and fertiliser — quantities, timing and current price estimates
  • Crop protection schedule, with product options at different price points
  • Irrigation setup and running costs across the season, if you use it
  • Labour hours per task at local daily rates
  • Projected yield, gross revenue and a clear profit & loss summary
At your OSAC centre

Take home a printed plan

Sit down with a trained agronomist who reviews your plan, adjusts it for your own parcels — soil, water source, last season's results — and prints a personalised plan you can take to the field, your group, or your bank.

Satellite field monitoring

Your field, watched from above.

Each week, satellite imagery of your registered parcels is analysed automatically — tracking crop health across the season and catching stress, uneven growth or an underperforming patch before it's visible on the ground.

  • A simple status — on track, or attention needed in a specific area
  • Nothing to buy and nothing to install — it runs quietly in the background
  • Flags trigger an agronomist follow-up when something needs a closer look
  • Works for any registered parcel, whatever its size

Free Sentinel-2 satellite imagery checks crop health every five days. Weather alerts don't just say "rain tomorrow" — they say "rain tomorrow, delay spraying" or "seven dry days ahead, irrigate Wednesday." Behind every centre, an operator dashboard runs the business: real-time stock with auto-reordering from the Hub, a farmer CRM, sales and offtake tracking, and performance against targets.

Built for real life
