Wakes you within a 30-min window when you start stirring
About this app
aka Alarm wakes you at the right moment within a 30-minute window you choose, instead of jolting you out of bed at a fixed time.
How it works: while an alarm is armed the app uses the microphone to measure the ambient sound level of your room. It maintains a rolling 5-minute baseline of "how quiet it really is" and watches for the level to rise above that baseline by a configurable threshold. When that happens — you turn over, sigh, shift the duvet — the alarm fires. If nothing happens, the alarm fires at the end of the window so you never oversleep.
Privacy: the microphone is active only while an alarm is set, and audio is processed in memory then immediately discarded. No audio buffer is ever written to disk, persisted, or transmitted off your device. There is no network code in this app at all — no analytics, no crash reporting, no third-party SDKs.
Features:
• Wake-up window with smart spike detection on the microphone • 60-second gradual volume fade-in for the alarm tone • Motion-driven snooze (lightly move the phone) with random duration clamped to the remaining window • Slide up anywhere to dismiss • Foreground service keeps the alarm reliable overnight • Material 3 UI with dark + light mode

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.aka.alarm 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, 1.1.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall aka Alarm 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 aka Alarm, and a listing is removed when the evidence for it stops holding up.
