Arcashift Explained: The Circadian Rhythm App Helping You Sleep Smarter

Let’s face it: for some of us, sleep is hard. Whether you’re pulling night shifts, catching flights across time zones, or just trying to figure out why your 3 p.m. coffee is ruining your 10 p.m. bedtime, staying in sync with your body can feel like an uphill battle. That’s where Arcashift comes in.

We made Arcashift to help you stop guessing and start sleeping better—with the power of circadian rhythms. Below, we’ve rounded up answers to some of the most common questions we get about what Arcashift does, who it’s for, and why it just might become your new favorite app.

❓ What is Arcashift?

Arcashift is a science-backed app that helps you sleep better, feel more energized, and align your daily routine with your body’s internal clock—aka your circadian rhythm. Whether you’re a shift worker, night owl, or just plain tired of being tired, Arcashift helps you get in sync.

⚙️ How does it work?

Arcashift uses your recent sleep and activity data to estimate your unique circadian rhythm. Based on that, it gives you personalized recommendations on when to sleep, nap, eat, drink caffeine, and get light exposure—so you can feel and function better around the clock.

👥 Who is Arcashift for?

If you’re dealing with inconsistent sleep, Arcashift was built for you. But we’re especially helpful for:

• Shift workers (nurses, first responders, IT specialists—you name it)
  
• People with irregular schedules or jet lag
  
• Wellness-focused users trying to optimize energy and performance
  
• Curious minds who want to learn more about how their body clock works

🧠 What makes Arcashift different from other sleep apps?

Most apps tell you what you did. Arcashift tells you when to do it.

We’re built on circadian science, not just sleep duration. That means smarter timing for everything from naps to caffeine to meals—because when you do things matters just as much as what you do.

💸 Is there a free version?

Yes! You can get started with our core features for free. Want access to premium tools like the caffeine calculator and calendar sync? We’ve got a paid subscription for that.

🔬 How accurate are the recommendations?

Our recommendations are powered by validated circadian models and developed by experts—like our CEO, Olivia Walch, PhD, who specializes in circadian rhythms. We combine real-world data with real science to bring you personalized, evidence-backed guidance.
