What it is

Kronos is a companion app for Call of Duty Zombies players, providing Easter Egg guides, interactive maps and in-app tools. Guides divide Easter Eggs into steps with screenshots, and players can check off objectives to track progress. The homepage says coverage spans more than 40 maps, from Nacht der Untoten to Shattered Veil. A Memorizer tool tracks Simon Says color and number sequences and includes a one-tap reset. Players can vote on the next CoD Revival and view a countdown and community vote results. Kronos works offline and syncs offline; its free plan requires no signup. For phone sign-in, it stores a phone number and Firebase user ID to sync progress, bookmarks and guide history across devices. Its privacy policy says Firestore access is restricted to the authenticated account and users can delete their account in app settings. Kronos is available on Android, iOS and web. The privacy policy also lists Firebase Authentication, Cloud Firestore, Analytics, Crashlytics and Cloud Messaging.
