For Colorado applicators

How COSprayLogs works

Log compliant spray records from your phone in minutes — not at the kitchen table after a long route.

Your workflow in the field

1
Start a spray job
GPS, start time, and local weather are captured at your application site — so you are not guessing wind later.
2
Confirm the details
Client, product, EPA number, rates, and your applicator info prefilled from your profile. Look up EPA numbers as you go.
3
Spray with a live timer running
Duration is tracked while you work. End weather is logged when you finish.
4
Save an audit-ready record
Every job lands in your history — print or save as PDF when a client or CDA asks.

Less field paperwork
Stop reconstructing the week from memory. Each job is logged while you are still on site.
Built for Colorado records
Time, location, weather, product, rates, and license fields aligned with what commercial applicators document every day.
Schedule before you roll
Add appointments with client and site details so techs arrive with context instead of digging through texts.
One logbook for your crew
Invite technicians to a shared team logbook so owners and field staff see the same spray history.
Works like an app on your phone
Add COSprayLogs to your home screen for quick access from the truck — no app store required.
History when you need it
Pull up past jobs, export summaries, and keep records organized for the three-year retention window.

COSprayLogs helps you document field work. It does not replace product labels, licensing, or official CDA guidance.
