## Description

Turf Tempo tells you when to reapply plant growth regulators (PGRs) — timed to the plant, not the calendar.

PGRs like trinexapac-ethyl, prohexadione-calcium, and paclobutrazol wear off on a schedule set by temperature, not by days. Turf Tempo tracks Growing Degree Days (GDD) from your local weather and shows you when suppression is fading — so you reapply on time, avoid rebound, and keep clippings and seedheads in check.

WHAT MAKES IT DIFFERENT
Most tools hand you a single number. Turf Tempo is honest about the science behind it:
• Targets adjust to your product, mowing height, season, and grass.
• Every target shows a confidence level — validated research vs. an educated starting point.
• At lawn height, where the research runs out, it starts conservative and dials the interval in to your turf as you log how it responds.

FEATURES
• GDD tracking from real local weather, per property
• Next-application forecast and a live progress gauge
• 7-day Spray Outlook: rain, wind, and heat suitability at a glance
• On-label awareness — products that aren't labeled for your site are flagged, with the reason
• Product, rate, and application history
• Optional cloud backup (email sign-in, no password)
• Reminders as you approach or pass your target
• A built-in guide that explains the model and cites its sources

WHO IT'S FOR
Sports-turf and lawn-care pros, and serious DIY lawn enthusiasts running a PGR program on greens, fairways, or home lawns.

Everything works on your device; an account is optional and only for backup.

Turf Tempo is a scheduling aid, not a substitute for the product label or professional agronomic judgment. Always read and follow the product label.
