A product recommendation system is a web, mobile, or desktop application that recommends products to users based on the user's preferences and previous purchases. Product recommendation systems may work directly with e-commerce sites or may be embedded in other applications such as news websites.

Product recommendation apps share many of the same features as other niche ecommerce apps. For example, some product recommendation apps have tools to help users build out wishlists or review products they own. Popular examples include Houzz, StitchFix, and Trunk Club.

• A wine recommendation app. The consumer will login, fill out a palate quiz, and get wine recommendations from the store. The wines will be ranked based off of the same quiz questions in order to recommend properly and will be done manually.

A product recommendation app uses user behavior data to recommend products according to a user's interests. If a user likes one product, the app is likely to recommend similar items in the future. In order for a product recommendation app to grow, it needs to provide users with incentives for interacting with the platform and with other users. It should also verify that its recommendations are valuable by monitoring user engagement with products they are recommended, and by measuring how many times they buy those products.

Product recommendation apps may face legal and reputational risks associated with the representation of product information, violation of vendor terms of service, and the transmission of sensitive information. Because these apps are often used in conjunction with ecommerce platforms, they must take care to comply with vendor requirements for both app development and data collection. Product recommendation apps should also consider syncing their data with a third-party point-of-sale system to allow merchants to easily verify that their inventory is being properly represented on your platform.
