Quick settings tile providing caffeine mode functionality (keep display on)
About this app
Caff provides a quick settings tile that allows the display to be kept on for an extended period of time. By tapping the tile, it is possible to toggle caffeine mode and cycle between different preset durations. The tile also serves as a countdown timer when caffeine is enabled. By long-pressing it, a preferences menu is shown, allowing the user to choose which durations will be cycled through. Additionally, there is an "infinite" mode, which will keep the display on indefinitely. Note
You may have to disable battery optimizations for the app to work.

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 cc.goll.caff 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 Caff, 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 Caff, and a listing is removed when the evidence for it stops holding up.
