Experience
Parts Town eCommerce App
https://apps.apple.com/us/app/parts-town/id399259573The Parts Town eCommerce app allows service technicians to buy parts and consult manuals for commercial kitchen equipment. The app has over 100,000 downloads and a 4.8-star rating on the App Store.
When a user views a manual, it is saved to the My Manuals section of the app, which is synchronized to all their devices.
The app also features an interactive wire diagram feature, which allows customers to view equipment schematics, tap the part in the diagram they want to buy, and add it to their cart.
Parts Town has skinned the app for some of its top customers and offered them a separate App Store listing.
