Your last set was 5 × 185. Lifty already knows, and it's telling you to put 195 on the bar today. That's LiftIQ. It reads what you actually lifted — not what a template says you should have — and calls your next weight before you've finished re-racking. Take the number or beat it. Either way you stop guessing. LIFTIQ Weight and rep suggestions on every set, pulled from your own history A one-line reason for each one, so you can overrule it when you know better Describe a split in a sentence — "6-day push pull legs, 60 minutes, dumbbells only" — and it builds the routines for you Got a plan on paper or stuck in another app? Photograph it. Each day comes back as its own routine. LOGGING THAT KEEPS UP Last session's numbers are already sitting in the fields. Two taps and the set is logged. Barbell, dumbbell, machine, cable, bodyweight, cardio, timed holds, single-arm and single-leg Supersets, drop sets, pyramids, warm-up blocks, rest timers A plate calculator, because nobody wants to do arithmetic at 6am WATCH YOURSELF GET STRONGER Volume and estimated 1RM charts, by muscle group and by exercise PRs caught the moment you hit them Lift Score turns a whole session into one number, so a great day and a phoned-in day don't look identical in your history Progress photos, and a monthly recap worth scrolling BRING YOUR FRIENDS INTO IT A live weekly leaderboard. Someone is always trying to pass you. A feed of your friends' sessions — react, comment, talk your trash Versus: one-on-one, or squad against squad Community challenges the whole app runs at once Collectible badges for the milestones you hit, parked on your profile FOLLOW THE ATHLETES YOU ALREADY WATCH Follow verified creators and their new routines land in your feed Download any of their programs into your library and run it like it's your own Join their collab challenges and find out where you land against everyone else training it ON YOUR WRIST AND YOUR LOCK SCREEN Log sets from Apple Watch without digging your phone out A Live Activity keeps your rest timer and set count on the Lock Screen Workouts save to Apple Health SWITCHING FROM ANOTHER APP Bring your history and your PRs across, so your charts don't restart at zero on day one. THE UNGLAMOROUS PART Works offline — gym wifi isn't your problem Sign in with Apple Block and report tools on every profile Delete your account and everything in it from inside the app. No support email, no waiting.
