App store optimization software can help you track app listings and assess their marketplace presence.

Check tracked app limits alongside free-plan availability and paid-from pricing to understand the access options shown. AppFollow, AppTweak, and ASOdesk are among the tools included. Consider which marketplaces you need to monitor, whether listing tests or localized listings matter to you, and how many apps you expect to track. Use those priorities to weigh the listed capabilities and plan details.
