Lacks features of its predecessor Sleep Cycle

Solid concept, but this app needs options for vibration and custom alarm sounds. This app is twice as much as sleep cycle and has a quarter of the functionality. Its like someone taking a feature in an app -- which is already a condensed, specific program -- and doubling the price. I cant recommend purchasing this until it drops in price and has more features. Optimistic to see what v1.1 brings.
