A minimalist hourly chime.
About this app
HRLY (Hourly) is a minimalist hourly chime app designed to help you keep track of time without constantly checking your phone. It uses a simple system of long and short tones to signify the hour, running quietly in the background.
✨ Features
- Simple Time System: Easily learn the time-telling system. - Customizable Sounds: Use your own audio files for both the short and long tones. - Notification Controls: Skip the next chime or stop the service directly from the notification. - Background Service: Runs efficiently in the background to chime on the hour. - Optional Visual Pulse: An optional visual pulse can accompany the chime on the lock screen. (Still working out some kinks) - User Control: Easily enable or disable the main chime service, visuals, and custom sounds. - Minimalist Design: A clean, no-frills interface. - Open Source: A "View Source" button provides a quick link to the project's GitHub page.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
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 com.ltrademark.hourly 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
If the current release misbehaves, 1.6 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall HRLY first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
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 HRLY, and a listing is removed when the evidence for it stops holding up.
