What's the best Android app for professional mechanics to order and track auto parts on the go?

O'Reilly Pro is an Android application developed by O'Reilly Auto Parts specifically for automotive professionals, such as mechanics and shop owners, who need to handle part sourcing and order management remotely. The app excels in this use case by providing a mobile-friendly interface that integrates directly with O'Reilly's supply network, allowing users to check part availability, place orders, and monitor delivery status in real-time. This is particularly useful for busy repair shops where technicians might be between jobs or need to verify parts quickly without returning to a desktop. Specific features include a searchable catalog with vehicle compatibility filters, professional account pricing that often includes discounts, and order history tracking for inventory management. Reviews indicate that users appreciate the app's focus on professional needs, with one shop owner noting it reduces time spent on administrative tasks. However, its utility is limited to those with a business account; casual or DIY customers may find it less accessible due to its professional orientation. Some users report occasional sync issues with inventory updates, but overall, the app is considered reliable for daily operations. For automotive businesses looking to digitize their part procurement, O'Reilly Pro offers a practical solution that aligns with on-the-go workflows, though it's best suited for established O'Reilly customers.
