Know what your body can do today.

PACE watches your heart rate, sleep, heart rate variability (HRV), noise levels, weather, and more all at the same time, all day long. It turns that into one clear number that tells you what your body can handle right now.

Pacing is a self-management strategy recommended by doctors for chronic conditions. It means matching what you do each day to what your body can actually handle that day instead of pushing through and paying for it later. Done well, pacing helps you do more over time, not less.

A crash (clinically known as post-exertional malaise or post-exertional symptom exacerbation) is when your body's response to overexertion catches up with you, sometimes hours or days later. You feel fine, do too much, then wake up the next day unable to function. PACE detects the warning signs before you cross that line.

No. PACE monitors you continuously in real time not just a morning snapshot. If your body signals stress or fatigue during the day, your score and suggestions update right away.

Your watch collects raw numbers. PACE tells you what those numbers mean for your day which tasks to skip, which to modify, and when to rest. It works with any wearable, not just Apple.

You can still use PACE. Log how you feel each morning and we build your score from your activity and symptom history. A wearable makes it more accurate but it is not required to get started.

Yes. Pacing is a widely used self-management strategy recommended by physicians for chronic conditions. PACE goes further it helps you track how your body responds to new treatments or routines over time, giving your care team real information to work with, not just your memory of how last month felt.

PACE is designed to support you and your care team, not replace them. Your care team can see your trends, track your response to new treatments, and use that information in your visits. In January 2026, the FDA (the US agency that oversees health products) updated its rules on clinical decision support software, making more room for tools like PACE that work alongside clinical care. We are in beta and working toward that recognition. Patent pending.

That is exactly what PACE is built for. You can reset your baseline any time things shift a new diagnosis, a new treatment, a better or worse stretch. PACE will then show you a before-and-after view so you can see what changed and when.

You do. Your electronic personal health information the kind protected under HIPAA is yours. We never sell it. You can export or delete everything at any time. See our Privacy Policy for full details.

No. PACE is built for anyone who wants to better understand their body's limits. Athletes, active professionals, and people focused on recovery use PACE to find the right balance between effort and rest, avoid overtraining, and build sustainable energy over time. You do not need a diagnosis to benefit from knowing your daily capacity.
