## What is Mettle?

Mettle is the strength coach that shows its work. Every set, rep and weight comes from a training engine that learns from your logs, and one tap on Why this? shows you the reason.

WHY THIS? ON EVERY LIFT
See the rule the engine applied, the sessions it came from and what happens next time. A weight goes up because you earned it, holds because a set was a grind, and drops on a planned recovery week. Nothing is a mystery.

A COACH YOU CAN QUESTION
Ask why your bench isn't moving and you get the engine's reasoning in a sentence or two, with your own sessions charted underneath. Ask how your squat is going, what your next workout is or how many sets you've done this week, and the answer comes straight from your log. The on-device model holds the conversation and picks exercises from a curated library of 263 lifts. It never sets a number.

PROGRESSIVE OVERLOAD, DONE FOR YOU
Load jumps when you're ready, back-offs when a lift stalls, plateau resets, training max cycles and deload weeks on schedule. Tell Mettle a set felt too light, just right or too heavy and the next sets adjust.

WORKS AROUND WHAT HURTS
Tell the coach your knee aches in a deep squat and it proposes a swap that spares the knee, lighter jumps on affected lifts and a weekly check-in. Every change is a card you approve. Nothing applies silently.

LOG FAST, EVEN LOCKED
One big Complete Set button, automatic warm-ups, plate math, timed holds for planks and carries, and rest alerts on the Lock Screen through a Live Activity. Short on time? Adapt today in one tap without rewriting your program.

APPLE WATCH
Start the workout, mark sets and rest from your wrist, with heart rate during rest.

SPEAKS YOUR LEVEL
Same engine, different words. A first-week lifter gets plain language and a veteran gets percentages, training max and RPE.

CLASSIC PROGRAMS OR YOUR OWN
Generate a program around your goal, days and equipment, or run a well-known published program as written, with Mettle's logging and explanations on top.

PRIVATE BY DESIGN
Your training, body metrics and conversations stay on your iPhone and sync only through your own iCloud. No account, no ads, no analytics. Apple Health is optional.

Mettle works fully without Apple Intelligence. The engine plans and explains every session either way.

FREE
Program generation, live workout logging, Why this?, the coach with memory, injury-aware programming, Apple Watch, widgets and Siri.

## Version history (last 2 releases)

### 1.0.1 — 2026-10-18

A coach that talks like a coach. Ask why a lift isn't moving and you get the engine's reasoning in a sentence or two, with a chart of your recent sessions underneath. Ask how a lift is going, what your next workout is or how many sets you've done this week, and the answer comes straight from your log.

Why this? now sits on the lift you're about to do. On Plan it explains the program you're actually running, and each lift shows the sets, reps and load the engine will prescribe today.

Mention pain and the coach leads with safety advice and never tells you to push through. Answer its question and it offers a swap for you to approve: the lift you named, replaced with one that spares what hurts, and a line on what the new lift trains. Short on time? It points you to one-tap Adapt today instead of rewriting your program.

Strength trends now leave out planned recovery weeks and lighter days, so the line shows real progress, and the chart says how many it left out.

Planks, hangs, wall sits and carries are prescribed in seconds, with a countdown for each hold.

Also new: a one-row warm-up card that folds away when you log your first set, a Today briefing in words that fit your level, a weekly review that leads with what moved and why, recovery signals compared with your own 28-day baseline, and set feedback that keeps the shape of the day's sets.

Fixes and polish: smarter progression for lifts trained twice a week, recovery weeks on schedule, short rests between warm-ups, better stand-in lifts on a no-barbell day, one Pro welcome after you buy, and faster Today and Progress with a long history. At the largest text sizes every main screen now reflows cleanly, and VoiceOver reads labels, not icon names. On Apple Watch, marking a set moves you straight to your rest, Mark Set is on the first screen, and the set screen says when your iPhone is out of reach. Tapping the Live Activity opens your workout, and a fresh install brings back your profile from iCloud.

Mettle works fully without Apple Intelligence.
