Hub
Know whether today is a push day or a back-off day.
RepEight’s Hub combines readiness, sleep, activity rings, muscle recovery, training load, VO₂ max and body composition from Apple Watch and Apple Health into one training snapshot.
Readiness with trends
A readiness score built from HRV, sleep and recent training load, with sparklines so you can see the trend, not just today’s number.
Muscle recovery
See which muscle groups are still recovering from your last sessions before you plan the next one.
Sleep, rings and VO₂ max
Sleep stages, activity rings and cardio fitness trends sit next to your lifting data instead of in a separate app.
Frequently asked questions
Do I need an Apple Watch for the Hub?
Readiness, sleep and VO₂ max need Apple Watch data through Apple Health. Without it, the Hub shows clearly labelled example data so you can see how it works.
More features
Apple Watch & Widgets
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.
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.
Train with a coach that remembers you.
