    Tips

    Pick once — you cannot rename later

    Match a domain you own. com.yourdomain.app is the safest pattern for review and for universal links later.

    Keep segments short. Long bundle IDs are valid but painful in logs and CI scripts.

    One app, one ID. Never reuse a bundle ID across unrelated products — Apple treats it as the same app lineage.

    FAQ

    Quick answers

    What is an iOS bundle ID?
    A bundle ID is a reverse-DNS identifier (e.g. com.acme.habits) that uniquely identifies your app on Apple platforms. You set it in Xcode and App Store Connect; it cannot be changed after the first upload.
    Should I use com or io for my bundle ID?
    com.company.app is the conventional choice for App Store apps. io.company.app is common for developer tools and web-first brands. Apple accepts both; pick one namespace and stay consistent across your portfolio.
    Can a bundle ID start with a number?
    No. Each dot-separated segment must start with a letter. This tool strips leading digits from slug segments and warns when inputs slugify to empty.
    Does the bundle ID have to match my company legal name?
    No. It should match a domain you control when possible (com.yourdomain.app), but it does not need to match your LLC name exactly.
    Is this the same as an Android application ID?
    Conceptually yes — Google Play uses an applicationId with the same reverse-DNS pattern. You can reuse the same string on both stores.
    Does this tool register the bundle ID?
    No. It only suggests strings. Register the ID in Apple Developer → Identifiers and in Xcode before you archive a build.
