A free and open source app that shows a large digital clock
About this app
When all you need is to know what time it is, only the actual time matters.
There are many wonderful clock applications available for Android devices. Many have have lots of great features. Choice in applications is a good thing.
When one wishes to choose a simple clock application that just displays the time of day in as large numbers as can fit on the screen's device, Just 24 Hours is here!
'''Features:'''
Just 24 Hours will display the time of day in 24 hour format in a big numbers as will fit on the screen. For those that were corrective lenses, it can be challenging to read small numbers when just waking up. Big numbers are required. No matter what size screen your Android device has, Just 24 Hours will use as big a text size that will fit on the screen.
That is all. No alarm settings. No typeface settings. No colour settings.
Just a big clock to see what time of day it is.
Of course, this is not what everyone wants in a clock application. This is okay. There are dozens of clock applications available for Android. Most (maybe all!) are great applications. We are certain that there will be one that will satisfy one's desired features. For those that just want the time, Just 24 Hours is here!

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.chancehorizon.just24hoursplus 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, 1.4.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Just 24 Hours 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 Just 24 Hours, and a listing is removed when the evidence for it stops holding up.
