Good morning
Sarah's Wellness Hub
AI Insight
Your sleep quality improved 23% this week. Based on your patterns, I'd recommend a 10-minute wind-down meditation tonight.
Every dimension of wellness, all connected
Each tracker feeds into the others. Your sleep data improves nutrition advice. Your cycle data adjusts fitness recommendations. Everything works together.
AI Wellness Coach
Your coach reads every log you make — sleep, mood, hydration, cycle — and responds to what's actually happening in your life, not a generic script.
GPT-4o PoweredHeart Rate & HRV
Camera-based heart rate and HRV monitoring that connects to your sleep and stress scores — so you can see recovery, not just numbers.
Real-timeSleep Tracking
Log sleep hours and quality each day. See how last night's sleep actually affected today's mood and energy — not theoretical averages.
CorrelationsEnergy & Mood
Track energy and mood as separate signals. The AI finds what's draining you — whether it's sleep debt, low hydration, or high-stress days.
Pattern DetectionHydration & Nutrition
Smart hydration tracking with goal setting, plus full nutrition logging with barcode scanner and AI meal planning. See how both affect your energy.
ConnectedAnalytics That Act
Instead of raw charts, get conclusions: 'Your mood is 24% higher on workout days' or 'Hydration drops below goal on 4 of the last 7 days'.
ActionableStreaks & Challenges
Daily check-ins, habit streaks, friend challenges, and global community goals that build consistency without turning it into a chore.
MotivatingPrivacy by Design
Bank-grade encryption · Your data stays yours. No ads, no data selling, no third-party sharing. Your health data belongs to you — always.
Privacy FirstFitness & Activity
GPS outdoor tracking, step counting, workout logging, and wearable sync with Fitbit and Oura — all feeding into your central wellness score.
GPS + WearablesLuna · Women's Wellness
Cycle tracking, phase-aware coaching, symptom logging, and fertility awareness — built with strict privacy standards and honest safety disclaimers.
Cycle-aware AIYou don't need 5 apps.
You need one that connects them.
Every app in your wellness stack has a blind spot. HEYLZY eliminates the gaps by tracking everything together — so the AI can tell you what individual apps never can.
Fitness app
(Strava, MyFitnessPal)
Tracks workouts and calories
Knows nothing about your sleep, mood, or cycle when it tells you to push harder
Habit tracker
(Habitica, Streaks)
Logs what you did
Can't explain why you broke your streak or what triggered it
Period tracker
(Clue, Flo)
Predicts your cycle
Can't connect your cycle phase to your energy dips, mood scores, or hydration
AI chat app
(ChatGPT, Replika)
Answers questions
Has no idea you slept 5 hours, skipped water, and had a hard week
HEYLZY
All of the above, connected
Tracks everything together. Your AI coach knows your sleep, mood, hydration, cycle, and fitness — all at once — so it can tell you things like: “Your mood is 24% higher on workout days” or “Fatigue spikes 3 days before your period starts.”

Testimonials from beta users
Sarah C.
Product Director
HEYLZY helped me notice patterns in how my mood and sleep affect each other. I'd been ignoring the connection for years. Now I actually track it and adjust.
Marcus R.
Startup Founder
I've tried a lot of wellness apps. HEYLZY is the first that adapts to how I actually live — not some ideal version of a wellness routine. The AI coach feels genuinely helpful.
Priya S.
Healthcare Professional
I appreciate that HEYLZY focuses on wellness tracking and education rather than making medical claims. The disclaimers are honest and the guidance is responsible.
James O.
Fitness Coach
Tracking how my training, sleep, and recovery connect was always scattered across different apps. HEYLZY brings it together and gives me useful context, not just numbers.
Elena V.
Engineering Manager
The buddy system keeps me accountable. My teammate and I nudge each other when we slack on check-ins. It's a small thing but it actually works.
Thomas M.
Wellness Coach
I recommend HEYLZY to clients for self-tracking between our sessions. It helps them build awareness of their patterns and come to sessions with more insight.
