IronOS Strength
by Data Driven Athlete LLC
Description
IronOS Strength is a free workout logger built for serious lifters. Log every set, track your progress, and measure your strength over time. Train with a coach, follow a program, or call your own shots.
DURABILITY SCORE
A strength retention metric that measures how well you're holding onto your strength as you age. Built on established powerlifting standards including DOTS normalization and IPF age coefficients, the score quantifies how much of your strength you're retaining, without ever needing to test a 1RM.
LOG WITH PRECISION
Pre-calculated warmups, automatic plate math, and RPE-based autoregulation. IronOS shows you exactly what to load, tracks your rest, and captures every rep. No spreadsheets, no guesswork.
TRACK WHAT MATTERS
IronOS tracks PRs automatically across every rep range. The Progress tab charts your top sessions over time for each tracked lift.
COACH INTEGRATION
Working with a coach? They see every set as you log it. They can add notes to individual exercises, leave session-level feedback, and review your form check videos. All in one place.
FORM CHECKS
Record and upload videos mid-workout with full context attached. Your coach reviews them alongside your sets, weights, and RPE, not in a separate thread.
BUILT FOR BARBELL TRAINING
Configurable bar weights, plate inventory, cable stack settings, and deadlift start weight. Equipment that matches your gym, not a generic default.
APPLE HEALTH
Sync bodyweight automatically. Your Durability Score stays current without manual entry.
Built for lifters who care about the long game.
