Intrepid Mac

Radio Alarm offers features and customization that far surpass Apple's native alarm, allowing you to set volume, snooze duration, and toggle fade-in for a less jarring wakeup. You can also choose from a variety of alarm sounds, from the classic "rooster" to the if-you-use-this-you're-probably-insane "scream." And if you want to make yourself earn a few more precious moments of sleep, you can set the app to snooze only after being shaken. If you need help falling asleep after waking up to horrible screaming sound effects, the app even has a sleeping aid mode, with the usual generic distant gulls and babbling brooks to comfort you at bedtime.
