Simple, unobtrusive chimes to help you keep track of the time.

    Just beeps, not a musical fanfare, so that you're not embarrassed in public! (For fancy chimes, I'd recommend Bellman)

    Tones at the top of the hour help you brush up on your binary too :). Some notes on how to decode the binary tones are below.

    IMPORTANT NOTE: Need to open app and press "Start Chimes" on first install.

    About the "prevent phone from sleeping" permission: This is just to keep the phone awake for a couple of seconds every 15 minutes, long enough to play tones. It shouldnt impact your battery life, and shouldnt make your screen turn on.

    ~~~ Binary tone notes ~~~
    Here's how you can decode the time from the tones.
    First, there is a low tone to let you know the sequence is coming.
    Then there will be 4 tones that represent the hour number in binary (or 5 if you have a 24hr clock enabled)
    A high pitch tone is a "1" and a medium pitch tone is a "0", and it counts from high bits to low bits.
    If you're not a programmer, that will sound overly complex, but it's not so bad when you get used to it.
    Here are some examples:

    1 oclock in 12hr clock mode:
    medium medium medium high = 0 0 0 1 = 1

    1am (01:00) in 24hr clock mode:
    medium medium medium medium high = 0 0 0 0 1 = 1

    2 oclock in 12 hr clock mode: medium medium high medium = 0 0 1 0 = 2

    11 oclock in 12 hr clock mode: high medium high high = 1 0 1 1 = 11 (=8*1 + 4*0 + 2*1 + 1*1)

    20:00 in 24 hr clock mode: high medium high medium medium = 1 0 1 0 0 = 20 (=16*1 + 8*0 + 4*1 + 2*0 + 1*0)

    and so on.

    Ok as it's simple & notifies, would be 5 stars if can fix/calibrate chimes, it used 2b off by 1 or 2 mins, now it's off by 5 mins. Looks like developer abandoned this app

    This app was one of my favorites but now it's useless sometimes 5 minutes late sometimes nonexistent. Needs some serious updating none since 2011!

    I have used this for years and it is bullet proof. Subtle and reliable. Would be great if it would recognize headset and Bluetooth to adjust volume accordingly.
