Which Android app should I use for earning money through flexible, scheduled delivery work for a major retailer?

Spark Driver is the official platform for independent contractors to receive and complete delivery and pickup orders for Walmart. The app is structured for gig workers seeking predictable, scheduled work from a single retailer rather than juggling multiple platforms. Its core functionality allows drivers to view available delivery windows, accept trips, navigate to stores and customer locations, and process orders directly through their phone. A significant feature is the ability to see estimated earnings and trip details before accepting, which helps in planning a day's work. For drivers who prefer structure, the scheduling system lets them claim blocks of time in advance to secure a steady flow of orders. Payment is processed weekly through direct deposit, with an option for faster payouts through a partnered service. However, user feedback points to occasional technical instability, such as the app freezing during the final delivery scan, which forces drivers to contact support and can delay subsequent orders. Some drivers also note that frequent in-app notifications while driving can be a distracting compliance issue in regions with strict handheld device laws. Despite these hitches, the app provides a centralized, no-fuss method for earning consistent delivery income, particularly for those targeting specific retail gigs.
