Workout tracking
Log fast. Change plans mid-set. Never miss a PR.
RepEight logs sets with your previous numbers pre-filled, detects personal records automatically, and lets you skip or replace an exercise for today only without changing your saved routine.
Skip or swap, just for today
Bench taken? Replace the exercise for this session only, or save the change to your routine. Skip and remove work the same way.
Automatic personal records
PRs are detected as you log: heaviest weight, best estimated 1RM, most reps and volume. You get milestones and badges as they stack up.
1,400+ exercises with demos
Every movement has a looping demo and target muscles, from barbell basics to cable and machine variations.
Programs and templates
Start from 27 official programs and 57 workout templates across strength, hypertrophy, hybrid, cardio, yoga and mobility.
Works offline
Sets save to your phone first and sync when you’re back online, so a dead gym basement never costs you a session.
Frequently asked questions
Does RepEight work without signal?
Yes. Workouts are stored on your phone first and synced to your account when you’re back online.
Can I change a workout mid-session without editing my routine?
Yes. Skip, replace or remove any exercise for the current session only, or choose to update the routine.

AI Coach
RepEight’s AI coach gives you a brief before each workout and a debrief after it, and answers questions about your lifts, all based on your actual training history rather than generic advice.

RepEight includes an Apple Watch app that can start a workout and hand it to your phone, a Live Activity that shows your current exercise and set in the Dynamic Island, and Home Screen widgets for PRs, streaks and stats.
Muscle Heatmap
RepEight’s muscle heatmap colours each muscle on a front and back body map by how much volume you’ve given it, so undertrained muscle groups stand out at a glance.
