Promise is an alarm clock that wakes you up with your own recorded voice messages.
At night, when your motivation is strongest, record a message to your future self: why you want to wake up, what you want to accomplish, or a promise you don't want to break.
When your alarm rings, morning-you hears exactly why you set it.
Instead of waking up to another sound you want to silence, wake up to a reason to get out of bed.
