Resyst: Fitness & Nutrition

Resyst brings your entire fitness routine into one app — training, nutrition, recovery, and an AI coach that actually knows your data.

TRAIN
Log workouts with a built-in rest timer, follow multi-week programs (home or gym), and track your progress over time. Choose from a large exercise library covering every muscle group.

EAT
Log meals from a large food database, or just snap a photo — Resyst's AI food scanning estimates calories and macros from a picture. Track your protein, carbs, and fat against personalized targets, scan barcodes, and time intermittent fasts.

RECOVER
Log your sleep to get a recovery score, track hydration, and build daily habits with streaks that keep you consistent. Resyst combines your sleep, training, and activity into a daily readiness score, so you know when to push and when to rest.

AI COACH
Chat with an AI coach powered by advanced AI that understands your workouts, nutrition, and recovery. Ask anything — why your readiness is low, what to eat for your goal, how to improve your sleep — and get personalized guidance. Generate a full weekly plan tailored to you.

TRACK YOUR TRANSFORMATION
Capture progress photos and body measurements over time to see how far you've come. Your photos stay private on your device.

WHY RESYST
- One app for the whole loop — no juggling five different trackers
- A readiness score that tells you how ready your body is to train
- AI-powered food logging and coaching
- Clean, fast, and built for real everyday use
