How to Update Horizon Launcher Without Losing Worlds or Mods

Updates frighten players in every launcher ecosystem, usually because of one bad habit: uninstalling first. With the build from Horizon Launcher APK, updating is deliberately boring. This guide gives the safe routine and explains why nothing you care about lives inside the files being replaced.

Update in place, every time

When the launcher or a build offers an update, accept it where it stands. The launcher downloads what changed, prepares the difference, and leaves everything else untouched. Your worlds sit in the vanilla save format outside the build, your settings live with the launcher, and your content mods stay installed per build.

The same rule covers updating the horizon launcher app itself from this site: install the new file over the existing app and Android keeps your data in place. An update in place is not a shortcut; it is the designed path.

After the update: the two minute check

Open the Versions page and let any pending preparation finish before launching. Then open your most played world, walk one familiar route, and open your modded world if you have one. Two minutes of checking beats a weekend of wondering whether something changed.

If a new build behaves oddly while your previous build was happy, the versions guide explains the two build habit that makes this a non event: keep the older build installed, play it, and let the new one catch up.

What carries across, and what does not need to

Worlds carry across because their format never changes. Mods carry across because they belong to the build shelf, not to a single file. Settings carry across because the launcher keeps its own house in order with self updates.

The only thing that does not carry across is the one time nature of the first prepare run, and even that survives in miniature: later preparations handle only what changed. the step by step install guide documents that first run if you ever set up a second phone.

Tested on our own Android phones with the current build, like every guide on this site. If a step behaves differently on your device, tell us through the contact page and the guide gets corrected, not defended.
