## What is HayRatio?

Plan hay with a range you can see and assumptions you control.

HayRatio is an educational forage-planning utility for eligible healthy adult horses. Start with a known scale weight or a clearly labeled eligible adult-horse measurement estimate. Choose your own planning percentage within a cited general range, then turn it into a practical hay plan.

PLAN WITH TRANSPARENT MATH
- See a daily 1.5% to 2.5% planning range and your selected target.
- Review every assumption, formula version, source version, and citation.
- Use pounds or kilograms with equivalent results.
- Calculate fully offline with no account.

TURN A TARGET INTO A SHOPPING PLAN
- Enter bale weight and an optional measured flake weight.
- Add expected waste and a planning horizon from 1 to 366 days.
- Add an optional bale price for a localized cost estimate.
- See the exact bale calculation and a practical whole-bale purchase count.

KEEP USEFUL RECORDS LOCAL
- Save your latest plan on your iPhone.
- Prepare dated PDF stall cards and shopping plans.
- Export or restore your local HayRatio archive without a subscription or network connection.
- Keep horse names, weights, measurements, notes, plans, and documents off our servers unless you deliberately share an export.

HAYRATIO PRO
The free app includes one horse, unlimited core calculations, the latest saved plan, sources, safety information, PDF exports, and data export and restore. HayRatio Pro unlocks unlimited horses and saved plans, history and seasonal planning, PDFs without HayRatio branding, and appearance options. Choose a one-time lifetime purchase or an annual auto-renewing subscription. There is no trial. The app always shows the localized App Store price before purchase.

IMPORTANT SAFETY BOUNDARY
HayRatio creates general forage-planning ranges. It does not balance a complete ration, analyze nutrients, prescribe grain, concentrate, supplements, salt, or water, diagnose or treat disease, or calculate for growing horses, pregnancy or lactation, acute illness, metabolic concerns, ulcers, or recovery diets. Individual needs vary with forage quality, pasture, body condition, activity, environment, and other feed. Confirm material changes with your veterinarian or equine nutritionist.
