Field Service Mobile App Builder customizes the Salesforce Field Service mobile app — page layouts technicians see on phones, custom components, offline data scope, feature availability. Different tool from Lightning App Builder; this one targets the dedicated Field Service mobile app, not the standard Salesforce mobile app.
- Confirm Field Service is enabled and the mobile app is licensed
Setup → Field Service Settings. Mobile app users need Field Service Mobile licenses.
- Open Setup → Field Service Mobile App Builder
Setup gear → Quick Find: Field Service Mobile → Field Service Mobile App Builder.
- Click into the mobile layout
Layouts target specific objects — Service Appointment, Work Order, Asset, custom objects.
- Drag components onto the mobile canvas
Compact / phone-shaped canvas. Components include field-display sections, related lists, custom Lightning components built for mobile.
- Configure offline data scope per layout
Pair with Briefcase Builder to ensure necessary data pre-loads. Layouts referencing data not in Briefcase fail offline.
- Test on a physical device
The mobile preview in the builder is approximate. Real-device testing surfaces touch-target issues, performance problems, and offline failures.
- Save and publish
Layouts apply to next mobile app sync.
Service Appointment / Work Order / Asset / custom.
Pair with Briefcase Builder.
Mobile-optimized LWCs for technician-specific UI.
- Field Service Mobile App and standard Salesforce Mobile App are different. Layouts here apply to the dedicated Field Service app — technicians using both apps see different UIs.
- Components must be mobile-optimized. Standard Lightning components built for desktop may not render or perform well on phones — test thoroughly.
- Offline behavior depends on Briefcase Builder. A layout component that queries data not in the Briefcase fails offline — validate data coverage.
