Crescendo Keeper

An alarm clock and timer that wakes you gently. Your alarm starts silent and rises smoothly to the volume you choose, playing the sound you choose.

A better way to wake up

Most alarms go from silence to full volume in an instant. Crescendo Keeper fades in instead, so you wake up to a sound that builds gradually rather than one that jolts you awake.

  • Use your own audio. Wake up to any sound file you like, not just the built-in tones.
  • A smooth crescendo. Volume rises gently from silent to the level you set.
  • More than an alarm. A timer and a stopwatch are built in too.

Why I built it

I wanted an alarm app where I could use my own audio files and also have the option to raise the volume slowly from silent. I could not find an app on the marketplace that did both, so I built my own.

Timer

Set a countdown for cooking, workouts, study sessions or a quick break, and let the app tell you when time is up.

Stopwatch

Time anything from a run to a presentation with a simple stopwatch, right alongside your alarms and timers.

Built, tested and used every day

I started with a simple concept and the basic functions it needed, then kept improving and testing it. Once I was happy with every feature, I used the app myself every day before releasing it. It is now going through the release process on the Google Play Store.
