ChemLog requires a ChemLog Pro subscription to access all features. A 7-day free trial is included automatically — no payment required to get started. Subscriptions are billed monthly or annually and can be cancelled at any time in your Apple ID settings. ChemLog is the spray record-keeping app built for farmers and licensed pesticide applicators who want compliant, professional records without the paperwork. LOG EVERY APPLICATION: Record chemicals, application rates, total volume, and area covered for each spray session. Weather data — wind speed, direction, temperature, and humidity — is captured at the time of logging so your records are always accurate. KNOW YOUR FIELDS: Add your fields once and link them to every session. Mark polygon boundaries on satellite imagery by tapping points around your field perimeter — ChemLog automatically calculates acreage so you don't have to measure it yourself. TRACK YOUR EQUIPMENT: Log which drone or sprayer you used for each application. Store FAA registration numbers, serial numbers, and equipment details in one place. MANAGE YOUR PILOTS: Store pilot profiles with their FAA Part 137 certificate, business insurance, FAA drone registration, and state applicators license — all in one place. Assign pilots to spray sessions and include them automatically in your PDF reports. IMPORT CHEMICAL LABELS: Scan the barcode on a pesticide container to pre-fill the EPA registration number instantly. Or import a photo or PDF of the label and let ChemLog read the product name, manufacturer, active ingredients, and EPA numbers automatically. ONE-TAP PDF REPORTS: Generate a complete, compliance-ready application record for any session in one tap. Professional PDF reports include all application details, weather conditions, field information, chemical data, and pilot information — ready to share with your agronomist, co-op, or for your own records. SHARE WITH YOUR CREW: Share chemical and drone records instantly with co-workers via AirDrop or Messages. One tap exports the record as a file — they open it and it imports directly into their ChemLog. EXPORT TO CSV: Export all your spray records as a CSV file for use in Excel, Google Sheets, or any record-keeping system your operation requires. ICLOUD SYNC: Your data stays in sync across all your Apple devices automatically via iCloud. Records logged in the field on your iPhone are waiting for you on your iPad back at the office.
