What's New in IronOS

2.3.0

November 11, 2026

COACH MODE Coaches can now sign in to the app and coach from their phone. • Inbox: every workout, comment, form check and message from your athletes, with missed sessions and high RPE flagged. Mark Looks good or swipe to dismiss. • Review workouts: watch form check videos beside the sets, reply on any exercise, and open an athlete's progress chart for any lift. • Messages: one conversation per athlete, live, with push notifications. • Programming: each athlete's calendar in week or month view. Build sessions with rep and RPE ranges, percentages, load and rest, request form checks, and move, copy, delete or save a session to your library. • Invite athletes, edit your coach profile, and choose which notifications reach your phone. FOR ATHLETES • Two accounts on one phone: switch from More or by tapping the IronOS logo. • Session length: the logger times your sets as you check them off, shows how long the workout took, and sends it to Apple Health. • Exercise history shows each session's estimated 1RM. • Moved sessions show where they came from, and the date picker marks the workout's current day. • Form check videos show their playback controls again. Hold a set's video button to replace or remove the clip. • Tapping a note in Feedback opens the workout right at that exercise. • A cleaner workout editor: tap an exercise to open it, long-press for options, swipe a block left to delete it. • You can log a set at 0 weight when you drop to bodyweight.

User reviews

Outstanding

I’ve used two other apps with a coach, and I actually log in THIS app and screenshot to paste into theirs. This is so superior to easily access previous lifts, track PRs, and most exciting it integrates RPE to every set. Best strength app out there!
