What Zenith Icon Pack is
Zenith Icon Pack is a themed icon set delivered as an app. Installing it does not change anything on its own; it simply makes a library of icons available to any launcher that supports icon packs. When you then choose "Zenith Icon Pack" in that launcher's icon-pack setting, the launcher swaps each app's default icon for the matching Zenith icon.
The pack has almost no interface of its own — applying it, browsing it, and assigning individual icons all happen inside your launcher, not inside the pack. So most "where is it" answers point at a launcher's settings, and the exact wording differs from launcher to launcher.
What is and isn't in the app
The pack is deliberately thin as an app:
- It has one activity that does nothing but show a brief reminder — "apply this pack from your launcher's icon pack settings" — and then closes. Tapping the pack in your app drawer is therefore expected to flash a message and vanish; that is normal, not a crash.
- It has no settings, no home screen, no account screen, and no assistant. Everything you do with the pack, you do from your launcher.
- It requests no permissions and talks to no server.
What the app does hold is the icon artwork itself and three pieces of metadata the launcher reads: the list of which icon maps to which app, the browsable catalogue grouped into categories, and the pack's identity. You never edit these by hand; the launcher consumes them.
How automatic theming works, in one paragraph
Each app on your phone is identified by a component name. The pack ships a large table pairing those component names with icons; when a launcher applies the pack, it looks up each of your apps in that table and, on a match, shows the Zenith icon. Apps with no entry keep their normal icon (see when an app has no themed icon). Because one icon can list several component names, a single Zenith icon can cover an app across its different versions and phone-maker variants.
