Three Protocols.
One System.
Your readiness score determines which protocol fires. No manual planning. No guessing. The app reads your body and deploys the right mission.

How We Read
Your Body
Three data streams. One readiness score. Zero guesswork.
01
HRV SignalHeart Rate
Variability
Variability
Your autonomic nervous system tells us more than you think. We sync with Apple Health to pull your morning HRV reading — the most reliable predictor of training readiness available without a lab.
02
Sleep IntelSleep Quality
Analysis
Analysis
Not just hours — quality matters. We pull total sleep from Apple Health and factor in your sleep debt trajectory. Miss a night before a night shift? The algorithm knows. Your training adjusts automatically.
03
Shift ContextCircadian
Penalty Model
Penalty Model
Night shifts suppress testosterone, spike cortisol, and destroy recovery for 48–72 hours. We apply a scientifically-grounded circadian penalty to your score based on where you are in your rotation.
Capabilities
Full Spec
Sheet
Everything built with shift workers in mind. Nothing that exists just to pad a features list.
Auto-fill from Apple Health
Open the app and your readiness score is already calculated. HRV and sleep pulled automatically — no manual entry required.
Progressive Overload Engine
The app tracks every set, every rep, every weight. Hit your targets 3 sessions running and it recommends adding 2.5kg. It knows your PRs.
Shift Schedule Builder
Set your weekly rotation once. The app reads today's shift type and applies the right circadian context automatically every morning.
Set-by-Set Logging
Log each set as you complete it. See your last session's numbers as a reference. PR detection fires a callout when you beat a personal best.
30-Day History
Sparkline charts, trend arrows, training load classification, and a full log of every session. See patterns emerge over weeks.
Offline-First Architecture
No signal in the station? No problem. Data writes to local cache first, syncs to the cloud when you're back online.
