Athleon
Strength training, understood.
Athleon logs every set in a tap, turns your history into insights you can read at a glance, coaches you right on your iPhone and lets you train side by side with friends.
For iPhone · No account needed · Your training stays in your iCloud
How it works
Plan it. Lift it. Watch it pay off.
-
Plan your training
Build templates from more than 300 exercises, or bring your routines and history over from Hevy, Strong or Fitbod.
-
Train with focus
Weights and reps carry over from last time, the rest timer starts itself, and your workout follows you to the Lock Screen.
-
Watch yourself improve
Every workout feeds your trends, personal bests, muscle recovery and a weekly goal ring that fills as you train.
Workouts
Log a set in a single tap.
The set list works like Reminders: tap a row to change it, drag to reorder, check it off when it’s done. Weights and reps carry over from last time, so most sets really are one tap.
- Templates for every routine, ready to start from the Train tab
- A rest timer that starts on its own after every set
- A plate calculator that shows exactly what to load on the bar
- List mode for the whole workout, or Focus Mode for one exercise at a time
Insights
Your progress, as clear as Apple Health.
Every set becomes something you can read at a glance: how your lifts are trending, which muscles you trained, how recovered they are, and how close you are to this week’s goal.
- A page for every exercise, with your estimated one-rep max, best sets and trend
- Front and back muscle maps of what you trained and what’s ready to go again
- Weekly goals with a ring that fills as you train
- Charts by week, month, six months or year
Athleon Coach
A coach that knows your training.
Ask anything about your training and get an answer grounded in your own workouts. Coach reviews each session, notices what’s improving and what’s lagging, and suggests what to change. It runs on your iPhone with Apple Intelligence.
- Ask Coach anything, in your own words
- A review after every workout, written like a coach would say it
- Suggestions you apply with a tap, never changed behind your back
- Every claim checked against your own data before you see it
Form Feedback
Check your form with your camera.
Prop up your iPhone and lift. Athleon follows your movement with on-device vision, then tells you in plain words what went well and what to fix, with the details there when you want them.
- Live cues while you train, or review a video afterwards
- Form History, to see how your technique changes over time
- Coaching first, measurements second, and never more certain than the camera can be
- The analysis runs on your iPhone
Train Together NEW
Train together, set by set.
Invite a friend into your workout and see each other’s sets the moment they’re logged, whether you share a rack or train across town. When you finish, the workout lands in both your histories.
- Start from any template, or straight from the Train tab
- Invite your circle, or send a private one-time link
- Everyone logs their own weights and reps
- Runs on iCloud, with no extra account
Social
Your gym crew, not the whole internet.
Share your workouts with a private circle of friends. Check in when you get to the gym so they know you’re training, and cheer each other on with likes and comments.
- Gym check-ins that end on their own
- A feed of your circle’s workouts
- Likes and comments, with notifications if you want them
- Private by default: only people you invite see anything
Live Activities
Your workout, right on the Lock Screen.
Lock your iPhone between sets and keep going. Your exercise, your next set and the rest timer stay on the Lock Screen and in the Dynamic Island, and you can log a set or skip the rest without opening the app.
Log Set
Check off the set you just did from the Lock Screen, and the next one is ready.
Rest Timer
Counts down in the Dynamic Island and on the Lock Screen, and tells you when it’s time.
Always Current
Updates the moment you log a set, even when you’re training together with a friend.
No account. No ads. No tracking.
Athleon has no sign-up and no servers that see your workouts. Your training lives on your iPhone and in your own iCloud, Coach and Form Feedback run on the device, and what you share goes only to the people you invite.
- No sign-up
- No analytics or ads
- AI that runs on your iPhone
- Shared only with your circle

FAQ
Questions, answered.
When can I get Athleon?
Athleon is in its final round of testing and is coming to the App Store soon. Email hello@getathleon.com and we’ll let you know the day it launches.
Which iPhones does it run on?
Athleon runs on iPhones with iOS 27. Athleon Coach writes its answers with Apple Intelligence on iPhones that support it.
Do I need an account?
No. Athleon uses the iCloud account already on your iPhone to sync your training, and for Train Together and Social, so there’s nothing to sign up for.
Can I bring my workouts from another app?
Yes, from Hevy, Strong and Fitbod. Athleon shows you how to export from each one, matches the exercises for you, and lets you review the matches before anything is imported.
Does Athleon work with Apple Health?
Yes. It can read your height, weight, age and sex to set up your profile, and save your workouts to Health. Both are optional, and you can change them any time in the Health app.
Who can see my workouts?
Only you, unless you share them. Social and Train Together share with the people you invite, through iCloud. The developer never sees your training. The privacy policy has the details.
