Peer selection
Same category, similar monetization, overlapping search intents. Ignore megabrands you will not outspend this quarter unless you are learning creative patterns.
Three peers, documented monthly.
What to capture
Icon, feature graphic mood, first three screenshots, short description, rating, review themes, and last update age.
When a peer ships a redesign, screenshot it — memory lies about how good their old page looked.
Automation
AuditHQ suggests similar Play Store apps and scores them on a schedule so competitive listing changes show up in your project timeline.
