Iridium vs Strong

Strong has the best pure logging experience on iOS. Iridium adds AI coaching, recovery programming, and nutrition. Two very different approaches.

TL;DR

Choose Strong if you follow your own program and want the cleanest, fastest way to log sets on iOS. Nothing beats its design.

Choose Iridium if you want the app to tell you what to train based on recovery, track volume science, and handle nutrition — all in one app.

Best iOS-native design. Strong feels like Apple made a workout app. Clean, fast, consistent with iOS conventions.
Excellent Apple Watch app. Log sets from your wrist, control rest timers, track your whole session without touching your phone.
PR tracking done right. Real-time PR notifications during sets, detailed history for every exercise.
Fast. Logging a set takes under 2 seconds. Minimal friction between you and your workout.

AI workout generation. Iridium builds your session. Strong logs it. If you don't have a program, Strong won't help.
Per-muscle recovery tracking. Iridium knows which muscles are ready to train. Strong has zero recovery awareness.
Volume landmarks (MEV/MAV/MRV). The science of optimal training volume, built in. Strong doesn't track this.
Nutrition tracking. Barcode scanning, AI food logging, macro tracking. You need a separate app with Strong.
Workout suggestions. Iridium tells you what to train. Strong tells you what you trained.

Slightly faster logging. Strong's minimal design means fewer taps per set. By a small margin.
CSV export. Export your full workout history for analysis. Iridium doesn't offer this yet.
