DropScout is a free iPhone app developed by Lonely Star Software Inc. that helps users track their Amazon products and receive alerts when prices drop. Users can set price alerts and choose to receive notifications via Push Notifications or Email Alerts. The app allows users to easily add and organize their Amazon products in a simple user interface, view price history to make informed purchasing decisions, and search for products directly within DropScout.

DropScout ensures anonymity for user accounts by default, prioritizing user privacy. Users also have the option to add their email to receive email alerts in addition to push notifications. The app supports various Amazon stores including the United States, United Kingdom, Canada, France, Italy, Spain, Germany, Poland, and the Netherlands.
