The latest version of Chrome on Android has started rolling out a new price tracking feature to alert you about price drops. SmartDroid reports receiving the new feature in Chrome version 90, though it doesn’t seem to be live for everyone. Once activated, Chrome monitors your open tabs for any price drops, and sends you a notification if any happen.
It could be a useful bit of functionality for the Android app, which isn’t compatible with price tracking extensions like Keepa that are available for Chrome’s desktop client. But the requirement that you keep a tab open in order to track its prices seems clunky. Hopefully Google finds a sleeker solution before the feature gets a widespread rollout.
