SunUp Reminder app for iPhone and iPad

SunUp sends you reminders every morning at sunrise, so you can get the benefit of early morning sunlight. It aims to be a "set and forget" solution that will automatically update the reminder time every day based on your location. Why? Not only is it a lovely time of the day to be outside, it also has numerous health benefits. SunUp was inspired by the Huberman Lab podcast. Prof. Huberman says: "Viewing sunlight within the first hours of waking (as soon as you can, even if through cloud cover) increases early-day cortisol release (the ideal time for elevated cortisol) and prepares the body for sleep later that night. A morning spike in cortisol will also positively influence your immune system, metabolism and ability to focus during the day.

Further, morning sunlight helps regulate your “circadian clock” — the body’s mechanism for anticipating when to wake up and go to sleep — and it manages other biological processes like hunger and body temperature. "
