An honest, feature-by-feature comparison. Sling's free plan is appealing — but once you need GPS tracking, payroll prep, and geofencing, the math changes.

Sling offers a free plan with basic scheduling and messaging for unlimited employees. However, the free plan lacks GPS time tracking, geofencing, labor cost tools, and payroll tracking and preparation. Their Premium plan ($2/user/mo) adds time tracking, and Business ($4/user/mo) adds labor cost and reporting. For a team of 25 employees on the Business plan, that is $100/mo — more than Staffapp.ai's $79 Growth plan which includes GPS geofencing, labor cost tracking, and up to 3 locations.
Sling's free plan does not include GPS time tracking. Their Premium plan ($2/user/mo) includes basic time tracking with location data, but geofencing is limited. Staffapp.ai includes GPS-verified clock-in with configurable geofencing on every plan, with per-worksite geofence controls on the Growth plan.
