Liftkin for iPhone
Get stronger together.
The training partner that helps you get into the best shape of your life, with friends who keep you going.
Compete on how much you've grown. Not on who lifts the most.
Your plan
Walk in knowing exactly what to lift.
Pick your goal, your days, and your equipment. Every exercise shows your next target, like "Try 190 x 5 today", based on your own history.
- Build muscle, get stronger, lose fat, or start from zero
- Full gym, dumbbells, or bodyweight at home
- A 4 week starter plan for your first time in a gym
- Step by step form cues and common mistakes for every exercise
Logging
Log any workout in seconds.
Weights, bodyweight reps, timed holds, and cardio with distance and pace. Tap the check on a set and it is saved.
- A rest timer that alerts you, even when your phone is locked
- Plate calculator and warm-up sets built in
- Finished workouts saved to Apple Health
Compete
Beat your friends by beating yourself.
Your weekly Improvement Score measures consistency, progress, and personal records relative to your own level, so a beginner and a veteran compete on equal footing.
- Squads with weekly head to head matchups and leaderboards
- Challenges: most sessions, most volume, biggest lift gain
- Personal record celebrations and shareable cards
How the score works
Fair for day one. Fair for year ten.
Every week you get an Improvement Score from 0 to 100. It compares you to you, so the person adding their first plate and the person chasing a new PR start the week even.
This week, for example
Improvement Score
Up 12 versus last week
- 40%
- ConsistencySessions this week versus your own weekly goal.
- 40%
- ProgressYour estimated one rep max versus your previous 4 weeks, adjusted for experience level.
- 20%
- Personal recordsNew bests earn points, whatever the number on the bar.
Sleep and Recovery scores work the same way: measured against your own baseline, so every device competes fairly.
Reels
Short clips. Real progress.

Three feeds
For you, Following, and My gym, so you see lifters like you and the people you train with.
Form checks
Friends vote "Looks solid" or "Fix this" and pin tips to the exact moment in the clip.
Verified PR clips
Weight and reps come from your log, not typed in, so a PR clip is the real thing.
Weekly vote challenges
Post your best clip, vote on others, and the winner earns a badge.
People at your gym
Find lifters who train where you do and follow them.
Safe by design
Report and block on everything, a content filter, and moderators who review reports.
Together
Friends who keep you going.
Cheer each other on, check each other's form, and show up for each other.
- Share a form check clip and get feedback from friends or your squad
- Pair with an accountability buddy and send a nudge when it is time to train
- Find your gym, check in, and meet lifters who are happy to help
Sleep and recovery
Recovery counts too.
Connect Apple Health to add sleep and recovery to your week, and compete with your squad on more than lifting.
- Weekly Sleep and Recovery scores against your own baseline
- Optional Sleep and Recovery leagues with your squad
- Squadmates see only your weekly score, never your health details
Daily readiness
A plan that listens to your body.
Liftkin reads last night's sleep, heart rate variability, and resting heart rate from Apple Health, adds your recent training, and tunes today's session.
- Push, Ready, Easy, or Recover, every morning
- Targets adjust: a little heavier when you are fresh, lighter when you are not
- Recovery sessions on rough days, with mobility, light cardio, and core
- A Why? button shows exactly what moved your score
- Deload and progress suggestions based on your week
You are always in control: tap Train as planned any day. Guidance, not medical advice.

FAQ
Questions, answered.
Is Liftkin free?
Yes. Liftkin is free to download and use, with no ads.
Do I need an Apple Watch or an Oura ring?
No. Everything about lifting works with just your iPhone. Connecting Apple Health is optional and adds weekly Sleep and Recovery scores, plus a daily readiness check that tunes your workout. An Apple Watch or an Oura ring works through Apple Health, since both sync your sleep and heart data there.
Who sees my data?
Friends see that you finished a workout and your weekly Improvement Score. Gym check-ins are visible only to friends. Health data, progress photos, and body measurements are visible only to you. Squadmates see your Sleep and Recovery scores only if you turn sharing on. Read the Privacy Policy.
Who can see my clips?
You choose: public, friends, your squad, or your gym. People you block never see them.
Does Liftkin adjust my workouts to my recovery?
Yes, if you connect Apple Health (including data from an Apple Watch or Oura ring). Each morning Liftkin checks your sleep, heart rate variability, resting heart rate, and recent training, then marks the day Push, Ready, Easy, or Recover and adjusts your targets. You can always train as planned instead.
Can I track macros?
Yes. Log calories, protein, carbs, and fat by searching foods or adding your own, with saved and recent foods one tap away. Liftkin suggests targets from your bodyweight and goal, and you can edit them. Targets are estimates, not medical advice.
I am a total beginner. Is it for me?
Yes. Liftkin has a 4 week starter plan for your first time in a gym, form cues for every exercise, and a score that measures improvement relative to your own level, so you can compete from day one.
What kinds of workouts can I log?
Weights, bodyweight reps, timed holds, and cardio with distance and pace.
Is it on Android?
Liftkin is built for iPhone.
How do I delete my account?
In the app, open Social, tap Edit profile, then Delete account. This permanently deletes your profile, workouts, photos, and messages.
