## What is StrengthOS Training?

StrengthOS is a local-first training companion for iPhone and iPad. Follow a structured program, record what you actually did, and understand your progress.

START WITH A PLAN
Choose a starter program for your equipment and schedule, download additional programs, or import your own StrengthOS program file. See your current session and every exercise planned for the week.

LOG THE WORK
Record sets, loads, repetitions, time, distance, and other movement-specific results. Add extra sets, record effort with optional set RPE, and save completed, partial, or skipped sessions.

STAY ON TIME
Use session and rest timers, local notification cues, and supported Live Activities. Your session timer remains accurate while you use another app.

SEE YOUR PROGRESS
Review movement history, personal records, estimated one-rep-max trends, adherence, and weighted strength trends across body regions. Progress charts summarize logged performance, not direct measurements of muscle growth.

OPTIONAL, PRIVATE INTELLIGENCE
On supported devices, Apple Intelligence can quietly summarize recent training on your device. A separate adaptive-load setting allows bounded, validated changes to upcoming loads, with visible explanations and undo. There is no chat interface, and AI is not required.

APPLE HEALTH, UNDER YOUR CONTROL
Optionally save completed workout summaries to Apple Health. StrengthOS does not read Health or sleep data and does not estimate calories.

OWN YOUR DATA
No account, ads, or third-party analytics. Your profile and workout history stay on your device unless you export them. Share program files or save a full local backup. An optional read-only online library supplies additional programs without uploading your training logs.

Requires iOS or iPadOS 26 or later. Apple Intelligence features depend on device and system availability. StrengthOS provides general workout planning and tracking, not medical diagnosis or treatment.
