Comparison

Duro vs Hevy

TL;DR: Hevy is a social workout logger with a free tier and a growing community. Duro is built for lifters who want per-muscle-group volume analytics against evidence-based growth zones. Choose Hevy if the social feed and free access keep you consistent. Choose Duro if you want to know whether each muscle group got enough volume this week.

Analytics

This is the biggest difference between the two apps — and it's the same gap Hevy shares with Strong.

Hevy shows you total volume lifted, a progress graph over time, and your estimated 1RM per exercise. It's the standard analytics package you'll find in most workout loggers. Useful for seeing whether your bench is trending up. Not useful for knowing whether your side delts got enough volume this week.

Duro tracks your weekly working sets per muscle group and plots them against volume landmarks (MV, MEV, MAV, MRV). Color-coded bars show which muscles are in the growth zone, which are maintaining, and which are approaching overtraining. You also get a full-body recovery map and PR tracking at every rep range — not just estimated 1RM.

Bottom line: Hevy's analytics tell you what happened. Duro's analytics tell you whether what happened was enough for growth. If you train for hypertrophy and want per-muscle-group feedback, Hevy can't give it to you.

Social features

Hevy built a social layer that a lot of lifters genuinely like. You can follow friends, share workout sessions, react to each other's training. If working out alongside a community — even digitally — keeps you showing up, that's real value. Plenty of lifters train harder when they know someone is watching.

Duro has no social features. No feed, no followers, no sharing. The entire app is focused on your training data and what it means for hypertrophy. Duro is a tool for one person looking at their own numbers.

Bottom line: Social features aren't a gimmick — they help some lifters stay consistent. But they're a motivation feature, not an analytics feature. If accountability from friends matters to you, Hevy has something Duro doesn't. If you're past needing motivation and want training quality data, the social feed won't help.

Workout logging

Hevy offers clean, fast logging. Enter weight and reps. Start and stop rest timers. Use templates for recurring workouts. The interface is well-built and has gotten smoother with each update. It's a good logger.

Duro has the same core flow — start a workout, log sets, rest timer between them. Templates, custom exercises, full history. Duro also shows your running volume zone status during the workout, so you can see how each set moves you closer to (or past) your weekly targets per muscle group.

Bottom line: Both apps log workouts well. The logging experience is comparable. The difference is what happens with the data after you log — Hevy puts it in a feed for your friends, Duro puts it through a volume analytics engine.

Pricing and the free tier

Hevy has a free tier that lets you log workouts without paying. There are limits — routine count, some analytics features — but the core logging experience works at $0. Pro unlocks everything for about $9/month.

Duro will be a paid subscription. Pricing isn't finalized yet. There's no free tier confirmed. If paying nothing is a hard requirement, Hevy wins by default.

Bottom line: Hevy's free tier is a genuine advantage for lifters who need a capable logger without a subscription. Duro is for lifters who've decided that volume analytics are worth paying for.

Privacy and data

Hevy requires an account and stores your data in the cloud. This enables the social features, cross-device sync, and web access — all of which require a server. The trade-off is that your training data lives on someone else's infrastructure, and the social features mean some of it is visible to other users by default.

Duro stores everything on-device. No account. No cloud. No sync server. Your data never leaves your phone. The downside: no cross-device access, no web dashboard, and no automatic cloud backup. If you lose your phone without a local backup, your data is gone.

Bottom line: If you want social features and cross-platform access, cloud storage is the necessary trade-off. If you'd rather your training data stay completely private and local, Duro doesn't touch a server.

Choose Hevy if

  • The social features keep you consistent — seeing friends train pushes you to show up
  • You need a free workout logger and can't commit to a subscription right now
  • You need Android support, web access, or cross-device sync
  • You want a community with shared routines and workout inspiration
  • You don't need per-muscle-group volume analytics

Hevy's ideal user: A lifter who trains with friends (or wants to feel like they do). They want a fast, free logger with a social layer that makes training feel less solitary. Analytics aren't the priority — staying motivated and tracking workouts is.

Choose Duro if

  • You train for hypertrophy and want volume analytics per muscle group
  • You've ever wondered "am I doing enough sets for this muscle to grow?"
  • You want to see which muscles are recovered before your next session
  • You care about PRs at every rep range, not just estimated 1RM
  • You've tried tracking volume in a spreadsheet and want it automated
  • Privacy matters — you want on-device storage with no account or social profile

Duro's ideal user: An intermediate-to-advanced lifter focused on hypertrophy who doesn't need a social feed — they need a dashboard. They know about volume landmarks, they've outgrown basic logging, and they want to see whether each muscle group is in the growth zone every week. The social features aren't a draw. The data is.

Where Duro falls short

We're a new app. Hevy has an established community and a track record of shipping updates. Duro hasn't proven itself yet — you'd be an early adopter.

Duro is iOS only. No Android, no web dashboard, no cross-device sync. Hevy works everywhere.

There's no free tier. Hevy lets you log workouts for free. If budget is a constraint, Hevy is more accessible.

Duro has no social features. If the community aspect of Hevy is what keeps you training, Duro doesn't replace that. You'd need to get your motivation elsewhere.

Hevy's exercise library is larger and community-contributed. Duro has 160+ exercises with muscle group classification, which covers the main compounds and isolations, but Hevy has more entries from user submissions.

If you want a proven app with social features, cross-platform support, and a free starting point, Hevy is the safer choice. Duro is for lifters willing to pay for volume analytics because the per-muscle-group data is worth it to them.

Switching from Hevy

What transfers

  • Full workout history — every exercise, set, rep, weight, and date. Export from Hevy as CSV, import into Duro with one tap.
  • Exercise names — automatically matched to Duro's library with muscle group classification.
  • Volume data — your historical sets get mapped to per-muscle-group zones immediately. Months or years of Hevy data become volume analytics in Duro.

What you'll need to redo

  • Templates — routine templates don't transfer. Rebuild them in Duro or use one of the 18 included programs.
  • Custom exercises — custom entries may need to be re-created and mapped to their primary muscle group.
  • Social connections — Duro has no social features. Your friends list, shared workouts, and reactions don't carry over.

How long it takes

The data import takes about 30 seconds. In Hevy: Settings → Export → CSV. In Duro: tap Import, select the file. Your training history appears with volume zones populated.

Rebuilding your templates and customizations takes another 10-15 minutes depending on how many you have.
