Pacer is protein-first, deficit-driven nutrition tracking — native to iOS 26 and macOS 26. Members get a tracker that does the math; their trainer gets Pacer Coach to program and monitor the whole roster in real time.
Pacer and Pacer Coach share the same plan — protein floor, calorie band, fasting window, exclusions — so what a trainer programs is exactly what their client sees.
Open the app, glance at the ring, follow the dinner cue. No spreadsheets, no calorie guesswork.
Program each client's plan once, then watch their rings and deficits update live. Spot who's drifting before the week is lost.
A central ring tracks every gram toward your 200g floor. The 1g = 4kcal rule is enforced, so impossible macros get corrected automatically.
BMR (2292) + Apple Watch burn − what you've eaten, in real time. The hero card shifts from green to crimson across five states.
Your 12:00–19:00 window, tracked to the second. Pacer knows when it's open, closing, or done — and adapts its guidance.
Rate satiety after lunch and Pacer suggests dinner — liquid protein when full, coast when the floor is met, top up when short.
Reads active energy, distance, and workouts. Offline-safe presets keep the math right; it always takes the higher of manual or watch.
Set allergens and ingredients once. Anything you log containing a blocked keyword is caught before it counts.
Tap a preset, drag the 0.5×–1.5× portion slider, and protein + calories update live.
Activity flows in from Apple Watch and feeds your live deficit automatically.
Follow the dinner suggestion to close the day on protein, in your deficit.
