About this app

Arcashift is a sleep app that cares about the rest of your life, too. Using a digital twin of your sleep and circadian rhythms, we tell you when to get and avoid light, eat, and stop caffeine to help you reach your goals—whether it’s waking up earlier, recovering from a late night, or handling your work hours.

The app works by first pulling in data from your Health app and other sensors (steps, heart rate, sleep, and phone accelerometer/motion data). Then it simulates a clone of your sleep system on your phone to design a plan that’s personalized for you.

Want to change your wake-up time? We’ve got the app for you. Want to track your sleep without a wearable? We’ll use sensors on your device to do it. Want to adjust yourself to a new time zone? Yep, we can do that. Learn what a digital twin of your sleep and circadian system can do for you today.

Key Features of Arcashift:
- Import your calendar and sync it with your circadian rhythms for optimal performance.
- Personalized recommendations tailored to your unique sleep patterns, work hours, and circadian rhythms.
- Realistic and achievable timing recommendations that seamlessly integrate into your life outside of sleep.
- Clear and intuitive interface for easy visualization.
- Insights and guidance on healthy sleep

I'm really liking this app a lot! it's helping me pay attention to my sleep habits throughout the day. I especially like the reminders/notifications to make me aware of what I need to focus on, and not forget about. it's definitely not intrusive, and if you have questions or concerns they get back to you! I get all that for free! they update regularly, but not excessively, you have to let the science do the job.

this app doesn't work... I keep adding things to the schedule but they don't appear no matter how many times I save them. Also refuses to connect to the health connect app, and the step tracker they offer in its place doesn't work either. Had the app for all of 15 min and I'm deleting it now

I've been trying this app along with another one, and the recentish improvements with the recommendations and the CALENDAR sync with Google calendar along with the jet lag calculation being built in have sold me on this app over a competitor that has separate apps for those functions.
