Now with a full running system: easy runs, intervals, tempo, hills and 10 ready-made programs — plus every exercise explained in your language.
SYNTRAX is your all-in-one AI health and fitness companion — track nutrition, build workouts, plan your day, and train together with friends and coaches.
SNAP YOUR MEALS
Just take a photo and SYNTRAX recognizes the dish and estimates calories and macros in seconds. No endless searching — point, shoot, and log.
TRAIN WITH A REAL LIBRARY
289 exercises, each with step-by-step technique, the mistakes people actually make, safety notes and pro tips — written in your language, not machine-translated. Tap muscles on the interactive body map to build a session around exactly what you want to train, or let the AI generator plan it around your equipment, time and recovery.
RUN PROPERLY
A complete running system, not an afterthought. Easy runs and long runs for your aerobic base, tempo work at threshold, 400 m and 1 km intervals, fartlek, hill repeats, strides and sprints. Walk-run intervals if you are starting from zero. Plus cycling, swimming, rowing, SkiErg, stairs, rucking and hiking — with ready-made programs from 5K Starter to Machine HIIT, and the drills and prehab work that keep runners healthy.
TRAIN TOGETHER
Share workouts and plans with friends, or work with a coach inside the app. Send sessions, follow progress and keep each other honest.
READINESS YOU CAN FEEL
Apple Health turns your steps, sleep, heart rate and activity into a daily readiness score. Insights show what is actually working, without burying you in numbers.
FOCUS AND SCREEN TIME
Set app limits, run focus sessions and see where your hours really go — all on-device.
PRIVATE BY DESIGN
Your health, focus and meal data stays linked to your account only. No ads, no tracking, no data brokers. Export everything or delete everything, anytime, in two taps.
SYNTRAX is not a medical device. Workouts, calorie targets and AI suggestions are general recommendations, not a health or nutrition plan for your individual situation — consult a healthcare professional before changing your diet or training, and stop any session that causes pain.
Health and fitness data is processed with Apple HealthKit and is never shared with third parties for advertising. Screen Time analysis runs entirely on your device through Apple's Family Controls framework.
Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in your App Store account settings.

What stands out here is how personalized everything feels. I really like that it takes multiple body factors into account instead of giving everyone the same recommendations. Because of that, the calorie estimates feel much more realistic. The app is also simple and convenient to use, which makes it easy to stay consistent.
Amazing!

Great app! All the most useful features are free. Calorie calculation, daily routine and much more in one place, which is very convenient, you don’t need to switch between different apps
love it
