Iridium vs Hevy

What Hevy does well

• Fastest logging in the category. Open, tap, done. Hevy stays out of your way.
• Generous free tier. 4 routines, full logging, and the social feed for free. Most people can get by without paying.
• Social feed. See friends' workouts, get accountability from the community. Strava for the gym.
• Everywhere you train. iOS, Android, Apple Watch, Wear OS, and web. Your gym buddy doesn't need an iPhone.
• Workout templates. Build a routine once, reuse it forever. Easy to share.

What Iridium does that Hevy doesn't

• Real-time set adaptation. Iridium watches how each set compares to its target and adjusts your remaining sets on the fly. Hevy logs what you did — it doesn't change the plan as you go.
• Fully personalized, recovery-aware workouts. Iridium builds each session around your recovery, equipment, history, and goals. Hevy added an adaptive generator (Hevy Trainer/HevyGPT), but neither factors in your recovery or biometrics — they build a plan up front, not around today's readiness.
• Steerable AI coach. Write custom instructions ("prioritize barbell compounds," "superset antagonist pairs") and Iridium follows them every session, plus a chat coach you can ask to modify the workout. Hevy has no AI coach.
• Nutrition tracking. Barcode scanning, AI food description, photo recognition. Calories, protein, carbs, fat. Hevy is workouts-only.
• Volume landmarks (MEV/MAV/MRV). Hevy shows your weekly sets per muscle group. Iridium goes further — mapping that volume against minimum effective, maximum adaptive, and maximum recoverable volume, so you know whether each number is too low, optimal, or too high.

What Hevy does that Iridium doesn't

• Social feed. Hevy's community is genuinely motivating. If accountability drives your consistency, Hevy wins here.
• Android support. Iridium is iOS only. If you or your training partner uses Android, Hevy works for both.
• Free tier. Hevy gives you meaningful functionality for free. Iridium is a trial then paid.
