About this app

Inertia Fit — Your Lifting Friends, Connected

The workout tracker for lifting friends—whether you train together or apart.

Different gyms. Different cities. Different schedules. Same crew. Inertia Fit helps you stay connected with the friends you used to lift with—and the ones you still do.

STAY CONNECTED
See what your friends are lifting—every exercise, every set, every rep. Watch them hit PRs. Celebrate their streaks. Know who's crushing it this week without having to ask.
• Full workout details in your activity feed
• PR and milestone posts when friends hit big moments
• Your Crew dashboard shows who's active
• Training partner stats track your history with each friend
• Find other members at your gym and grow your crew

LIFT TOGETHER, WHEREVER YOU ARE
Can't make it to the same gym? Lift at the same time anyway. Start a joint session with a friend and train "together" from anywhere—see their progress in real time and send support mid-set.
• See when friends are lifting right now
• Join their session or invite them to yours
• Watch their sets come in as they lift
• Send encouragement that shows up between sets
• Schedule workouts so friends can plan to join you

COMPETE IF YOU WANT
Nothing pushes you harder than knowing your friend just beat your numbers. A little friendly rivalry keeps things fun—and keeps you both coming back. Turn it on when you want the extra push, or leave it off entirely.
• Try any friend's workout with their exact sets and weights as your target
• Create challenges with deadlines and see who tops the podium
• 6 leaderboard categories: volume, intensity, consistency, PRs, and more
• All competition features are optional

A TRACKER THAT STAYS OUT OF YOUR WAY
Fast logging. Auto rest timer. Smart suggestions that know what's next. Everything you need to track your training without slowing you down.
• Copy your last performance with one tap
• Rest timer starts automatically after each set
• Green when you beat your numbers, red when you don't
• Suggestions based on your schedule, rotation, and recovery
• Supersets, circuits, cardio—all supported
• No ads on workout tracking screens

MAKE IT YOURS
• 100+ custom avatars
• Earn archetypes and titles based on how you train
• Unlimited splits, workouts, and custom exercises
• Granular privacy controls—choose what's visible to friends

Why Inertia? An object in motion stays in motion. Inertia Fit connects you with your crew—so you keep each other moving.
