Doesnt work properly

I used Pillow (premium version) for a week. It never woke me up as the smart alarm. The alarm rings always exactly on time and not even a minute earlier. So the beautiful layout of the app doesnt matter as the app doesnt do what should be its basic functionality. Other apps do it better. I regret buying the full version of Pillow.
