Finding package names & URL schemes

Android package names

The package name is the app’s unique ID. Easy ways to find it:

Play Store URL: open the app’s page on play.google.com. The id= value in the URL is the package name. For example play.google.com/store/apps/details?id=com.whatsapp → com.whatsapp.
On a connected device: adb shell pm list packages | grep -i whatsapp

iOS URL schemes

iOS doesn’t let you look up apps by bundle ID. You check whether some installed app can open a URL scheme, so you need a scheme the target app registers.

The app’s developer docs. Many apps document their deep links (for example Google Maps uses comgooglemaps).
The app’s Info.plist. If you can get the .ipa, look under CFBundleURLTypes → CFBundleURLSchemes.
Trial and error on a device. Type scheme:// into Safari’s address bar. If the app opens, the scheme works.

Pass the scheme alone, like whatsapp. whatsapp:// and whatsapp: are accepted too and trimmed for you.

These are commonly used identifiers. Apps can change them, so test on a real device before you ship.
