The landing page for the feed calculator

The brief

It started as a Python calculator for working out the nutrient balance for a horse. Horse owners otherwise calculate by hand or in spreadsheets, with nutrient values scattered across feed suppliers' sites. The question was whether the calculation could become a service more people could use.

How it was built

The calculation engine was ported to TypeScript and given a React interface. Horse profiles and feeds are stored in a Prisma model, subscriptions go through Stripe and the landing page explains the value without hiding the calculator.

What was built

  • Calculation engine for nutrient balance
  • Horse profiles and feed database
