Hevy caps your free plan, costs nearly twice as much for Pro, and puts your workouts in a social feed. SuperFlex is the private, full-featured alternative with an unlimited free tier, a muscle recovery tracker, and half the price.

Hevy is a solid app. But for serious athletes who care about privacy, value, and training intelligence — these differences add up fast.
Hevy's free plan caps you at 4 routines, 3 months of workout history, and 7 custom exercises. SuperFlex is unlimited on the free plan — no caps, no walls, no nudges to upgrade just to see last month's data.
SuperFlex Pro is $4.99/month. Hevy Pro is significantly more expensive. Same category of features, but the savings on SuperFlex compound to hundreds of dollars over a few years of serious training.
Hevy is built around a social feed where you follow friends and share workouts publicly. SuperFlex has no feed, no followers, and no public profiles. Your training data stays yours — full stop.
After every session, SuperFlex shows you a per-muscle-group recovery status and suggests what to train next. Hevy tracks your volume but doesn't help you plan recovery. SuperFlex closes that gap.

Being Honest
Hevy is genuinely one of the best workout apps on the market. Here's where it has a real advantage.
Hevy launched Hevy Trainer in February 2026 — an AI coach that suggests progressions and adapts your training. SuperFlex doesn't have this yet. It's on the roadmap for Phase 2, but if you want AI-driven programming now, Hevy has the edge.
If you want to follow friends, share workouts, and stay accountable through a community feed, Hevy's social platform is genuinely good and well-built. SuperFlex intentionally has none of that — it's a privacy tradeoff, not a capability gap.
Hevy runs on iOS 14.1+, meaning it works on older iPhones going back several generations. SuperFlex requires iOS 17.0+. If you're on an older device, Hevy is the practical choice.
