How it works
Android has two volumes.
VolūM keeps them apart.
Your phone has one volume for what you listen to and another for your alarm. But apps, casts and system events can change both. VolūM watches the alarm volume all night and puts it back the moment anything lowers it. Nothing else changes about your phone; your alarm app stays your alarm app.
The bedtime check
Before you sleep, VolūM checks three things: an alarm is set, it is loud enough to wake you, and your phone will not switch protection off overnight. Each result is a chip; anything amber comes with the fix for your exact device.
Set tonight's sound
One vessel, two levels. Drag in the water to set how loud your show plays; it can fall all the way to silence. The bright line is your alarm volume. Moving it takes a deliberate press and hold, so nothing moves it by accident, least of all an app.
The moon dial sets the fade: your show gets quieter over five minutes to two hours, then pauses. Your alarm is not part of the fade.
One tap
Protect my alarm. That is the whole ritual. The screen exhales, the line stays lit, and you put the phone down. You can pause or stop protection at any time, including at 2 a.m., quietly, without a bright screen in your face.
While you sleep
A single quiet notification is the guard's face for the night. If something lowers your alarm, it is put back straight away, usually within a second, and the event is written to the night journal. No sound, no lit screen, no drama.
If your phone's battery manager stops VolūM, it does not pretend. The notification says protection was interrupted, and the morning report shows exactly when and for how long, with the fix for your device.
The morning report
You woke on time. Then the evidence: a three-second replay of the night, the line dipping and snapping back at each save, and the full journal underneath. Every entry is a fact your phone recorded, kept on your phone.
What VolūM does not do
Plain limits, stated up front.
VolūM does not set alarms; it protects the one you already have. It does not record audio, read what you play, or need an account. It cannot ring a phone that is off or flat; the bedtime check warns you about battery before you sleep. And on a few aggressive Android builds it needs one extra setting to survive the night; the check walks you through that once.
