GạoGas is a free iPhone app developed by Truc Nguyen that aims to streamline the competitive Gạo-gas business. In this industry, distributors expand their market by sending teams to each house and room to stick their store's phone number over others or remove existing phone numbers and replace them with their own. This repetitive and costly process makes it difficult to maintain a stable customer base. GạoGas app is designed to encourage customers to call GạoGas through their respective distributor's app. Users can accumulate reward points for purchasing 1kg of rice or 1 gas canister, or by referring others to install the GạoGas app.

With GạoGas, users can easily create orders for delivery by assigning them to a specific employee. The app also provides directions to guide the delivery personnel to the customer's designated location. This feature ensures a smooth and efficient delivery process, saving both time and effort.
