Great

Fantastic app. Recommended it to a professor after just two days.

Been using it for nearly a decade and a half since. Ensures I feel well-rested when I wake up. The few times a year I use a regular alarm I can feel the difference in the morning.

Every couple years update this review. I really hope they keep supporting this amazing app.
