Train smarter. Your coach in your pocket.
LiftIron is more than a logbook. It reads your training history to recommend your next set, tracks your cardio with GPS and live heart rate, and keeps every rep private in your own iCloud.
Built to coach, not just record
Most trackers store numbers. LiftIron turns your own history into guidance.
Adaptive Strength Coach
Analyzes your logged sets to suggest your next weight and reps, estimate your one-rep-max trend, and flag plateaus before they stall your progress.
Cardio with GPS & voice
Track walks, runs, and rides with live distance, pace, and route. Optional voice updates read out your stats every few minutes — great with headphones.
Apple Watch, cardio-first
Start a workout from your wrist with live heart rate and active energy via HealthKit. Sessions count toward your Activity rings.
Private by design
Your data lives in your own iCloud and syncs across your devices. No accounts, no third-party servers, no tracking, nothing sold.
Routines & rest timer
Run saved routines or build a workout as you go, with a visual rest countdown and configurable default rest length.
Your history, exportable
Review past sessions and trends, and export everything to CSV or JSON whenever you want. It's your data.
