Kronos

Kronos is a companion app for Call of Duty Zombies players working through Easter Eggs and looking for map guides and puzzle aids. Its walkthroughs divide objectives into steps with screenshots, and players can mark progress as they go. The homepage says the guide collection covers more than 40 maps, from Nacht der Untoten to Shattered Veil. A Memorizer tool keeps track of Simon Says color and number sequences and includes a one-tap reset. Players can also vote on the next CoD Revival and see a countdown and community results. Kronos works offline and syncs offline; its free plan requires no signup. Phone sign-in stores a phone number and Firebase user ID to synchronize progress, bookmarks, and guide history across devices. The privacy policy says Firestore access is limited to the authenticated account, and account deletion is available in app settings. Kronos is available on Android, iOS, and web.

Kronos brings walkthroughs, maps, and sequence tracking together for Zombies players. Offline access and a no-signup free plan are useful points to weigh alongside its narrow game focus.

Kronos suits Call of Duty Zombies players who want step-by-step Easter Egg guidance, progress tracking, and puzzle-sequence help. It may also appeal to players who want to participate in CoD Revival voting.

Kronos is a Call of Duty Zombies companion centered on Easter Egg walkthroughs, interactive maps, and puzzle aids. It suits players tackling multi-stage objectives who want a progress record on Android, iOS, or the web. The narrow Zombies focus is its chief strength and its clearest boundary.

Overview

Kronos has been developed since 2016/17, primarily by Allan with community help on guide content. Its purpose is practical: keep an Easter Egg run organized, provide map context, and replace paper notes for sequence-based puzzles. More than 40 maps are covered, from Nacht der Untoten through Shattered Veil, giving dedicated Zombies players a substantial single-game reference.

Key features

Walkthroughs divide Easter Eggs into individual steps, pair instructions with screenshots, and let players check off objectives. Progress tracking makes it easier to resume an unfinished run instead of reconstructing what has already been completed. Interactive maps add spatial context to those instructions, so Kronos is more useful during a live attempt than a purely linear text guide.

The Memorizer is a focused tool for Simon Says color and number sequences. It records the sequence and provides a one-tap reset, which is valuable when a puzzle attempt fails or must be started again. This specialization is helpful for Zombies players but does not make Kronos a general-purpose guide platform.

Kronos says it works and syncs offline, an important advantage where a reliable connection is not available. Players can also vote on the next CoD Revival and see a countdown and community vote results. Those events add participation around the guides without changing the app's core, game-specific purpose.

Pricing

The Free plan costs nothing, requires no signup, and works offline. It includes interactive walkthroughs, progress tracking, mobile apps, and offline access. That combination makes the free tier a straightforward choice for players who only need the guides and tools on one device or who prefer not to create an account.

Phone sign-in is relevant when continuity across devices matters: Kronos stores a phone number and Firebase user ID to sync progress, bookmarks, and guide history. Firebase security rules restrict Firestore access to the authenticated account, and account deletion is available in app settings. Users who want cross-device history therefore trade the no-signup simplicity for account data sharing.

Platforms

Kronos is available on Android, iOS, and the web. Having both mobile apps and browser access suits players who switch between a phone during a game and a larger screen while preparing. Offline operation further favors mobile use away from a stable connection.

Who it's for

Choose Kronos if you regularly complete Call of Duty Zombies Easter Eggs and want step-by-step objectives, map support, sequence tracking, and resumable progress. It is especially appropriate for players who value offline guides or who need a dedicated Zombies reference rather than broad coverage of multiple games.

Look elsewhere if your interests extend beyond Call of Duty Zombies, or if you want a guide service built around a wider catalogue. Kronos's specialization is useful only when that is the game you are playing.

Pros and cons

• Pros: More than 40 map guides; screenshot-backed, checkable walkthrough steps; progress, bookmark, and guide-history syncing; offline use; a dedicated Simon Says sequence tool; Android, iOS, and web access; no-signup free plan.
• Cons: The feature set is confined to Call of Duty Zombies; cross-device syncing requires phone sign-in and associated account data; community voting is supplementary rather than a replacement for the core guides.
