Everything in. Your session out. Strength IO reads everything you do: your lifts, the runs, rides and games you log in other apps, and your recovery from Apple Health. Then it builds the strength session your body can handle today, and an AI coach explains why. WHAT IT DOES • Workouts built for your week: every muscle gets the sets it needs, with the right mix of movements. Your main lifts rotate among your favorites, and accessory lifts vary. • Weights anchored to real effort: each lift's weight comes from your own history. Heavy lifts that load your spine keep a rep in reserve, and tired muscles get pulled back. • AI coach: a short daily overview of your vitals, sleep and training, plus a note on your training load, built on Apple Intelligence. • Your whole week counts: logged a run in Strava, a ride on Peloton or a game in Apple Fitness? Strength IO reads it through Apple Health and adjusts today's lifting. No double-logging. • Readiness from five overnight signals: HRV, sleep, sleeping heart rate, breathing rate and wrist temperature, each judged against your own normal and combined into one daily estimate. It shows exactly what's lowering or raising your score. • Training load: your last 7 days against your usual 28, with a clear read on whether you're ramping up too fast, holding steady or backing off. • Records and plateaus: personal records for every lift, and early warning when one stalls. • Ready for iOS 27: heart-rate zones from your Apple Watch, and Siri answers about your readiness and today's workout. • Private by design: the AI coach uses Apple's models only, on your iPhone or on Apple's Private Cloud Compute. Never a third-party AI. BUILT FOR The multi-sport lifter. If you train 3–4 times a week, wear an Apple Watch, and also run, ride or play, Strength IO reads all of it. STRENGTH IO PRO Strength IO starts with a free trial of the full app, nothing held back. After the trial, a monthly or yearly subscription keeps everything unlocked. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your App Store account settings.
