I9 Shop is an Android shopping application developed by KiaApp for I-9 Industrial Group (i-9.ir), an Iranian supplier of industrial machinery, valves, HVAC systems, pumps, and building equipment.

Founded in 2014, I-9 combines specialist product sales with technical consultation and after-sales support, serving individual buyers and businesses across sectors including oil and gas, agriculture, food, and pharmaceuticals. I9 Shop extends that industrial retail business to Android for its Persian-speaking audience.

This case study showcases my work as the app’s developer, including screenshots, development decisions, and implementation details. The application and I-9 brand belong to I-9 Industrial Group.
