Live Wallpaper simulating the brownian motion of particles in laser light
About this app
This is an Android Live Wallpaper that simulates the appearance of the Brownian motion of particles under a microscope illuminated by colored laser light.
Such observations are a classical physics experiment, but also used eg. in microrheology to measure the viscosity of mucus.
The live wallpaper is highly optimized, running on the GPU, to keep the battery drainage as minimal as possible.
To set it up, you might need to use a Wallpaper app (eg. the Google one) since some launchers don't allow installing live wallpapers.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be io.github.dergenaue.brownianparticles is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for Brownian Particles Live Wallpaper, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Brownian Particles Live Wallpaper, and a listing is removed when the evidence for it stops holding up.
