Cowculator

The problem

Cattle auctions move fast. Tracking bids, calculating price-per-kg, comparing to target prices, and remembering what you bought is near impossible with a pen and notepad. By the time you get home, you’ve lost track of what you paid and whether it was a good deal.

What we built

Cowculator is a mobile cattle auction companion that calculates live P/kg as bids change, tracks every purchase and market observation by gender, and gives you instant analytics: profits, price trends, time-to-slaughter projections, and shareable auction summaries.

Tech used

Offline-first mobile app built with React, Capacitor, and Zustand. Real-time bid calculations, animated UI with Framer Motion, full data export/import, and native Android share integration.

The outcome

Farmers walk out of auctions knowing exactly what they spent per kilogram, how it compares to previous sales, and when each animal will be ready for slaughter, all from their pocket, no spreadsheets needed.
