## What is Apex?

Your body provides the data. Apex Intelligence gives you the answers.
Other apps show you numbers. Apex Athletic tells you exactly what to do with them — train or recover, backed by YOUR HRV, sleep and strain.

ASK YOUR AI COACH — GET REAL ANSWERS
"Should I train hard today or take a rest day?"
"Why is my recovery low this week?"
"Build me a muscle-building plan around my schedule."
No generic tips. Every answer is based on your actual health data from Apple Health and Apple Watch. Your AI coach learns your patterns — and your plan stays fully adjustable via chat, anytime.

UNDERSTAND YOUR BODY AT A GLANCE
* Recovery Score — training readiness from HRV & resting heart rate
* Strain & Energy Level — real-time load and remaining capacity
* Sleep Analysis — quality, stages, and sleep debt
* Stress Score, VO₂max & heart rate zones

DISCOVER YOUR BIO AGE
How old is your body really? Apex calculates your biological age from 10+ markers — including your Pace of Aging, so you can see whether your lifestyle is speeding you up or slowing you down.

LOG FOOD IN SECONDS
Snap a photo or scan a barcode — calories and macros are detected automatically. Then see how your nutrition actually affects your recovery. No manual entry.

FIND WHAT WORKS FOR YOU
Track 100+ habits (alcohol, caffeine, meditation and more). Apex automatically correlates them with your recovery and shows you what's helping — and what's holding you back.

WHY APEX ATHLETIC
* A personal AI coach, not a static dashboard
* Workout plans that adapt to your daily recovery
* Deep Apple Watch, widget & Apple Health integration
* Available in English, German and Spanish — with elegant Dark Mode

Stop guessing. Start understanding.
Download Apex Athletic and ask your AI coach your first question today.

### 5/5 — Übersichtlich und verständlich

*2025-04-20, version 1.1*

Tolle App! Übersichtlich und und verständlich aufgebaut. Finde es schade, dass es keine Familien Freigabe gibt. Bin gespannt auf weitere Updates.

### 5/5 — Perfekter Schlaftracker

*2025-04-04, version 1.1*

Ich nutze die App ausschließlich zur Schlafüberwachung und nicht zum Sport. Für mich ist das die beste und übersichtlichste App dafür, weil sie nicht nur die Schlafqualität ermittelt, sondern mit diesem Wert, der Schlafdauer und anderen Vitalwerten einen nachvollziehbaren Erholungswert ermittelt.
