Broken sleep. Brain fog. Exhausted for no reason. You're not imagining it. Your symptoms aren't random. You just couldn't see the pattern. Until now.
See how it works
What's happening
You've noticed it. Sleep that doesn't restore. Energy that disappears mid-afternoon. A recovery score that says “great” when you feel anything but. You're not imagining it, and it's not just stress. Something shifted in your body, and nothing in your health stack can tell you what.
Your Apple Watch has been collecting the evidence the whole time. It just wasn't designed to interpret it in this context.
Same data, different lens
Your Apple Watch collects excellent data: heart rate variability, sleep stages, recovery metrics. Periclue evaluates that same data differently. Not through generic scoring algorithms built for athletes, but through the lens of what actually drives your sleep quality, recovery, and daily energy.
Where a standard app sees “4 awakenings” and moves on, Periclue asks: when did they happen? How did they fragment your deep sleep? What does this pattern mean for your specific baseline this week?
The connections
Your brain fog on Tuesdays. The sleep disruption that follows a specific phase of your cycle. The correlation between this week's training load and tomorrow's fatigue. These patterns exist in your data already. Scattered across apps that don't talk to each other.
Periclue connects sleep, recovery, activity, symptoms, and cycle data in one place. 26 pattern detectors run continuously, surfacing the correlations you'd never spot on your own.
Sleep. Recovery. Activity. Cycle. Symptoms. Nutrition. Supplements. Labs. All scored together, calibrated to you.
01
Sleep tracking. Recovery monitoring. Activity scoring. Adaptive bedtime recommendations. Smart wake alarm. Nutrition logging. Guided breathing. Cycle tracking. Symptom journaling. All in one place, all talking to each other, so you don't have to piece it together yourself.
02
Most health apps score you against a population average. Periclue scores against your personal baseline, and goes further: your cycle phase, your health conditions, your medications. Your HRV the week before your period means something different than the week after. Periclue knows the difference.
03
26 pattern detectors run continuously across your health data. Brain fog triggers. Sleep fragmentation trends. Energy-cycle correlations. Connections between symptoms and factors you'd never think to compare. Periclue surfaces them before you have to ask.
04
Ask Periclue why you're exhausted, and it reads your sleep data, HRV, activity load, cycle phase, and symptoms. All at once. It remembers your history between conversations and grounds every response in peer-reviewed research. Not a chatbot with health tips. An AI companion that knows your data.
05
Every recommendation becomes a trackable personal experiment. Structured protocols with measurable outcomes. Not just “try magnesium,” but a timed approach you can follow, track, and evaluate. Labs and doctor notes uploaded, findings extracted, follow-ups tracked.

Every algorithm decision traces back to published, peer-reviewed research.
A 2026 global study of 17,494 women across 158 countries found that the #1 health complaints aren't the ones most apps track. Exhaustion (95%), fatigue (93%), and irritability (91%) top the list. Most health apps weren't built for that. Periclue was. Our scoring engine prioritizes sleep fragmentation, recovery depth, and energy patterns, because the research says those matter most.
Periclue does not diagnose. It contextualizes your health data and surfaces patterns worth paying attention to. When something looks concerning, it encourages a conversation with your healthcare provider, not a self-diagnosis.
Most health apps fund their business by selling your data to advertisers and insurance companies. Periclue doesn't. Your HealthKit data is never sold, never shared, and never used for ads.
Research-backed insights on what your data really means.
You've been exhausted in a way sleep does not fix. Your brain does things it never used to do. Your doctor says everything looks fine. Here is what nobody has told you yet.
The worst part wasn't the symptoms. It was the months of not knowing why they were happening.
You slept 8 hours but feel terrible. The problem isn't how long you slept. It's how many times you woke up.

Yes. Periclue connects to Apple Health and reads data from your Apple Watch. No additional hardware needed.
Your Apple Watch collects great data but interprets it using generic algorithms built for athletic recovery. The symptoms women actually report most (exhaustion, brain fog, broken sleep) aren't things most health apps even measure. Periclue reads the same data through a different lens, one built on research into how these symptoms connect to sleep architecture, cycle patterns, and recovery. It scores against your personal baseline and surfaces the connections generic apps miss entirely.
No. Periclue works with passive Apple Watch data alone. Logging symptoms like hot flashes, mood, or energy improves AI insights but is completely optional.
Your data stays yours. It is never sold, never shared with advertisers, and never used for anything other than generating your personal health insights. AI conversations use zero-retention processing. You can request full data deletion at any time.
Any AI can answer health questions. Periclue is different because it's your health database with a smart assistant inside. Your sleep, recovery, activity, cycle, and symptom data all live in one place. The AI doesn't just read it, it tracks your baselines, detects patterns across weeks, and builds structured routines you can follow and measure. No general-purpose AI does that.
No. Periclue is a wellness tool, not a medical device. It contextualizes your data and flags patterns worth paying attention to. When something looks concerning, it encourages a conversation with your healthcare provider.
iOS beta is live now with early access users. Public App Store launch: Spring 2026. Android follows.
