Actually unlimited free tier
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.
Hevy Alternative
Hevy is popular for a reason.
SuperFlex is built different.
Hevy caps your free plan 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 per-limb tracking built in.
Where SuperFlex Wins
Four reasons lifters are switching
Hevy is a solid app. But for serious athletes who care about privacy, value, and training intelligence - these differences add up fast.
Per-limb unilateral tracking
Single-arm rows, split squats, lunges - SuperFlex tracks reps and weight per limb, so a 5lb left-right imbalance shows up in your data instead of hiding inside a bilateral total. Hevy logs unilateral work as a single movement.
Private by design
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.
Muscle recovery tracker
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
Where Hevy has the edge
Hevy is genuinely one of the best workout apps on the market. Here's where it has a real advantage.
Lower Pro pricing
Hevy Pro starts at $2.99/month, with yearly and lifetime options that undercut SuperFlex Pro ($5.99/month). If you know you'll pay for Pro features and want the lowest subscription price, Hevy wins on cost. SuperFlex's counter is a free tier with no caps at all.
Built-in AI coach
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.
Community and social features
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.
Broader iOS compatibility
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.
