About this app

AEONIX is your companion for body recomposition – building muscle and losing fat at the same time, instead of forcing you to choose between the two. Whether you're a beginner, coming back after a break, or already advanced: AEONIX adapts to your level, your equipment, and your daily life.

17 carefully built training programs for every situation: Recomp Starter for beginners, 12-Week Recomp for advanced lifters, Glute Focus, Upper Body Strength, Knee-Friendly, Gym Power, Bodyweight Only, Standing Only, Summer Body, Thanksgiving Burner, Back Strength, Express 15-Minute, Postnatal Recovery, Senior Fit, Travel Workout, Calisthenics Advanced, and Mobility & Stress Relief. Every program gives you day-by-day exercises, sets, reps, and weight guidance – with alternatives for home, travel, or a fully equipped gym. Two programs are free, the remaining 15 unlock with AEONIX Premium.

The Today view shows you exactly what's on the schedule: your current training day, your weekly overview, and your training streak – the run of trained days that keeps you motivated. One tap starts your guided workout session with step-by-step instructions; finished sessions are saved automatically to your workout log.

In the Data section you enter your weight, height, age, and level and get a well-founded estimate of your body composition. You can enter a measured body fat percentage or let AEONIX estimate it – the app clearly marks whether a value is measured or estimated. It also calculates your personal macro targets: calories, protein, carbs, and fat, tailored to your recomposition goal.

The Guide section delivers solid knowledge on training, nutrition, and science – why progressive overload works, how protein intake drives muscle growth, and why sleep and recovery matter. Twelve articles are free, two in-depth pieces are part of Premium.

A short onboarding at first launch walks you through your goals, level, equipment, and body data – AEONIX then recommends matching programs and macro targets. The app comes in an easy-on-the-eyes dark mode design, fully available in German and English, with secure login via Sign in with Apple and cross-device sync.

AEONIX Premium unlocks all 17 programs, every Guide article, and your full body composition breakdown – ad-free, as a yearly or monthly subscription.

Health notice: AEONIX supports your training and nutrition but does not replace individual medical advice. If you have health conditions, are pregnant, or have pre-existing conditions, consult a doctor before starting. Body fat and calorie values shown are estimates, not medical diagnoses.

Start with AEONIX today and bring training, knowledge, and progress together in one place.
