How to find App IDs?
App IDs are unique identifiers that allow Similarweb’s APIs to locate and return data for specific mobile applications. Every app on iOS and Android has a distinct identifier that serves as its “address” in our system.
Why you need App IDs
- Required for all app-related API calls and data requests
- Enable precise app targeting in competitive analysis
- Essential for tracking app performance and market intelligence
Quick reference
Android | Package name | com.whatsapp |
iOS | Numeric ID | 310633997 |
App IDs are case-sensitive, especially for Android apps. Always use the exact capitalization as it appears in the app store.
