This keeps your compliance records accurate without extra paperwork after the Job. --- ### #### Who uses this feature - Technicians - Applies to all business types - Primarily benefits Pest and Lawn trades #### Feature configuration - This feature is currently in **Private Preview** and available for specific accounts. It is subject to change. If you want to enable this feature for your account, join the waitlist [here](https://docs.google.com/forms/d/e/1FAIpQLSe3PjljkyHhHohts6zw74O5o0ac8l7GMwuKM_csKVbSVCpVMg/viewform). - The Field Mobile App is optimized for iOS, iPadOS, and Android phones and tablets. For more, see System requirements and mobile app information. - If you're using the Field Mobile App and need support, please contact Technical Support (through the office) or reach out directly to support@servicetitan.com. ## Things to know - The *Chemicals* section only appears on a job once you've added at least one chemical from the Pricebook. - *Chemical Quantity* is calculated automatically from *Solution Applied* and *Dilution*. You can't edit it directly — it's always *Solution Applied × Dilution*. - To track chemical Lots, your office must use the Purchasing module and configure lots there. - Applicator name, license number, and application *timestamp* are automatically recorded based on the first technician to arrive at the job. These details can’t be edited in the Field Mobile App. - If you've logged this chemical at this location before, select it under Previously Used to prefill most fields — you'll only need to confirm the amount applied. - The Field Mobile App doesn’t deduct chemical inventory when you log an application. *Chemical Quantity* is used for billing only and uses the unit of measure configured in the chemical’s *Pricebook Inventory Settings*. ## Best practices - Use the **On Your Truck** filter to find your chemical faster. When the filter is active, the app shows the truck it recognizes as yours. If you’re borrowing a different truck, or need a chemical that isn’t loaded on the displayed truck, clear the filter. - Use **Previously Used** at the top of the chemical picker before searching the full catalog—it shows chemicals you've logged at this location before. - Complete all required chemical fields before closeout. Job closeout is blocked until every logged chemical has its required fields filled in. ## Use cases - A pest control technician treats a home for fire ants and logs the Cypermethrin EC application, including solution applied, dilution, and target pest, before moving to the next stop. - A technician working without a signal in a basement or crawl space enters a full chemical application offline. The entry syncs automatically once the device reconnects. - A technician returns to a property treated last month and reselects the same chemical from Previously Used instead of re-entering every field. ## Log a chemical application during a job 1.
