Effort in. Strength out. Strength IO reads everything you do: your lifts, the runs, rides and games you log in other apps, and your recovery from the Health app. Then it builds the strength session your body can handle today, and tells you why. Start with a free trial of the full app. READY FOR iOS 27 • Recovery HRV: Apple's new overnight measure of heart-rate variability, from Apple Watch Series 12 and Ultra 4. • Heart-rate zones come straight from your Apple Watch. • Siri answers about your readiness and today's workout. 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. • A daily overview: where you stand this morning, the one or two things behind it, and what that means for today, plus a note on your training load. • Your whole week counts: logged a run in Strava, a ride on Peloton or a game in Apple Fitness? Strength IO reads it through the Health app and counts it toward your training load and readiness. 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 estimate that updates through your day. 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. • Privacy first: what the app reads, and where it goes, is set out in plain words on our privacy page. 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.
