One logger. Every athlete. Only your tools.
Reconfigures to whoever holds it. Breadth in the schema, restraint on the screen.

One logger.
One logger.
Every athlete. No friction.
One app that becomes the exact tool you need — powerlifter or climber, standing or seated, day one or year ten — and the only one honest enough to say when a number doesn’t apply. Tap Begin, or just say “two-twenty-five for five.”
We'll let you know when there's room.

Four reasons, before the catalog.
Four structural commitments the incumbents can’t easily copy.
Analytics that conclude — not just chart.
Every chart carries a plain-language verdict line. The sentence first, the chart as evidence.

It tells you what to look at first.
Pretty charts are table stakes. The verdict line on top is the difference.
“Stalled 4 weeks on Bench.”
RPE drift“Squat volume +12%, RPE held.”
Work, not strain“Rear delts: 0 sets in 14 days.”
Coverage gap“80%+ of work above last block.”
Intensity skewIt knows when to back off.
The sports-medicine layer, in your pocket. It informs the decision — never makes it, never diagnoses.
ACWR load ratio
Acute-to-chronic workload, with caution bands. (Gabbett, 2016.)
Per-set pain log
NRS 0–10, tied to the exact set that produced it.
Big-jump warning
A pre-log nudge when today spikes past your trend.
Rehab stream
Return-from-injury work tracked apart from load.
It feels like the iron.
Ambient intelligence over explicit UI — and generative art that’s yours alone.
Weight-aware plate physics
The buttons settle slower under heavier load — spring response scales with the weight on the bar.
Haptics that escalate
Light, medium, heavy taps that grow with the lift. You feel the set log without looking.
PR territory glow
The screen warms as you approach a personal record. Ambient information — no badge, no popup.
Gym color temperature
The background shifts a few degrees of hue per gym. Your home rack feels like your home rack.
Every set, in your Health database. Yours to take.
Most apps write a black-box envelope. flexRep preserves every set — and never holds it hostage.
Per-set HealthKit metadata
Weight, reps, RPE, and set type ride along as HKWorkoutEvent data — both directions.
Free export, every column
CSV (two formats), JSON, and a SHA-256 .flexrep bundle. Bodyweight, added-load, assist-load — all there.
Importers are first-class
Bring your history from Strong and Hevy with quality-tier provenance. No lock-in, by design.
The honest line
Evidence you can check. Conclusions you own.
Cite the literature and name its limits. Your own trend is the only study that’s about you.
- Cite the science, name its limits. Every formula sourced; every methodology card states what it doesn’t support.
- Your n=1 is the only study that’s about you. Descriptive, never prescriptive — you stay the author.
- No anxiety treadmill. A calm Sunday read, opt-in in depth — never “you’re leaving gains on the table.”
Honest enough for everyone who trains.
Inclusivity is structural, not decorative — and accessibility is a feature we lead with, not a checkbox we hide.
Adaptive identity
Wheelchair, single-arm, and block variants are first-class — surfaced at the top of the picker, scored honestly or not at all.
Live VoiceOver
Generated labels on every Canvas chart. The glyph and waveform describe themselves out loud.
Measured contrast
WCAG-checked color, opaque surfaces under Increase Contrast, differentiation that never relies on color alone.
Dynamic Type & calm motion
Hero numbers scale with UIFontMetrics. Every repeating animation routes through one Reduce-Motion gate.
Your training has a face.
Three living visuals, each driven by your record. Same algorithm as the app.
Eleven athletes. One app. Pick the door that fits.
Each archetype meets the version of flexRep made for their hand — same schema underneath, a different surface on top.
The Powerlifter Numbers that hold under load. The Bodybuilder Volume the literature would recognize. The Program Runner Your block, as a real graph. The Coach Hand a clean JSON to anyone. The Lifter Managing Pain Train hard. Train smart. Train forever. The Returning Lifter Show up. Tap. Lift. The Climber Hangboard edges and V-scale grades, first-class. The Olympic Weightlifter Sinclair, not Wilks — a separate scoring discipline. The Strongman Athlete Yokes, sleds, carries, atlas stones — modeled. The Grip Athlete Joint angles, per-set grips, fine forearm radar. The Hybrid Athlete Strength + conditioning, one logger, honest math.
There’s a lot in here. On purpose.
A sweep of the rest — each one its own page when you want the depth.
Voice & hands-free
Hold-to-talk, AirPods press, “Hey Siri,” and an eyes-free loop.
Focus Mode
A stripped max-effort surface for the heavy single.
Guided cluster sets
Intra-set rest, tracked, with plate-aware drop suggestions.
Coach Digest
A one-page markdown hand-off for your human coach.

Durable wrist queue that survives a dead pocket phone.

Places
Per-gym plate inventory and color temperature.

The songs that were playing your last twelve PRs.

Weight, body fat, tape, photos — read the slope.

Hundreds of curated lifts, alias-tolerant search.

Rest timer and set count on the Dynamic Island.
