What's the best iOS app for gig workers who shop for and deliver retail orders with route management tools?

Spark Driver is a platform designed for independent contractors who handle shopping and delivery tasks for Walmart orders. It suits individuals seeking flexible, on-demand work where they can accept jobs based on their availability, manage orders directly through the app, and receive support for issues like navigation or customer interactions. Specific features include real-time job offers with estimated earnings, in-app navigation for delivery addresses, and a built-in system for scanning items during pickup, which streamlines the process from store aisles to customers' doors. For use cases like grocery deliveries, the app allows drivers to view item lists and store layouts, though some user feedback points to a common request: a 'Skip' button to rearrange items for more efficient in-store picking, avoiding backtracking. Reviews indicate that the support team is responsive, which helps resolve problems like order discrepancies or account issues. However, limitations exist, such as potential waiting lists in certain areas and occasional app updates that may temporarily affect stability. In real-world scenarios, drivers can log in during peak hours to secure higher-paying batches, making it a viable option for supplemental income. The app's interface is generally intuitive, but new users might need time to adapt to the order flow. Overall, Spark Driver balances job accessibility with practical tools, yet minor imperfections like the missing route optimization feature highlight areas for growth.
