When a Plus store installs a rival, they are shopping your category. When they uninstall one, the replacement window is wide open. Alert catches both the instant they happen.
Track app stack changes across Plus stores and know the moment a competitor is added or dropped, long before it would show up anywhere else.
Stack changes on Plus stores, matched to your competitor set.
Define the rival apps that matter and we watch them all.
Uninstalls score highest, the replacement window is open now.
Install signals come from Alert's own continuous crawl of live storefronts, detecting the apps a merchant actually runs and catching the change when a rival appears or disappears. For backend apps with no storefront footprint, public reviews attest the install, labeled as exactly that. You see both, honestly separated.
Alert fingerprints apps live on merchant stores and revisits to catch changes.
A rival landing is a warning; a rival leaving is the warmest outreach you will send this week.
Detected on the storefront or attested by the merchant's own review; the card says which.
