ZON vs Hevy: which app for athletes who train more than one thing?
Hevy is the best pure strength tracker in the world. ZON is what you switch to when one log isn't enough: when you also run, do Hyrox, want an AI coach, or need nutrition in the same app.

The short answer
If you only lift, Hevy is hard to beat: fast, polished and proven by 13 million athletes. But the moment your training includes running, Hyrox or conditioning, Hevy leaves you stitching apps together. ZON is built hybrid-native: your lifts and runs live in one timeline, with AI debrief, daily readiness and nutrition in the same app. For athletes who train more than one thing, ZON is the better home.
- Choose Hevy if
- You train one thing: the barbell.
- Choose ZON if
- You lift and run, or do Hyrox, CrossFit, hybrid.
- Honest note
- We build ZON. We've kept the wins Hevy genuinely earns.

The breakdown
Where each app pulls ahead
The decisions that usually settle it, including the ones where the other app is the right call.
The AI gap
Hevy's AI is an off-app algorithm (Hevy Trainer) plus a Custom GPT on chatgpt.com. ZON ships six AI surfaces inside the app: Debrief, Readiness, Form Check, Copilot, Magic Import, Insights. A coach you talk to, not a draft to import.
ZON- Six AI surfaces inside the app
- Post-session Debrief rates every session
- Form Check video analysis via Gemini Vision
Hevy- Hevy Trainer is an algorithm, not chat AI
- HevyGPT lives on chatgpt.com, not in-app
- No form check, no mid-session copilot
Hybrid training: built-in vs Strava-handoff
Hevy is a strength tracker by design: no native GPS, runs handed off to Strava. ZON tracks lifts and GPS runs in the same workout, with ACWR analytics and Hyrox station templates. One app, one log, one progression curve.
ZON- Native GPS run tracking
- Strength + GPS run in one workout
- ACWR analytics + Hyrox templates
Hevy- No native GPS: duration-based cardio only
- Runs handed off to Strava
- No unified hybrid load picture
Where Hevy is genuinely stronger
Hevy has refined its strength UX since 2019: 4.9★ across 250k+ ratings. Cheap entry ($2.99/mo) and a $74.99 lifetime ZON doesn't match. If you only lift, don't care about AI feedback and want the lowest cost, Hevy is the right call.
Hevy- Six years refining strength UX
- 4.9★ across iOS + Android with 250k+ ratings
- Lowest entry price + $74.99 lifetime
ZON- Younger product, growing fast
- No lifetime tier: AI cost basis
- Smaller, younger community
Nutrition: in the same app or in a second one?
Hevy doesn't track nutrition, so you pay MyFitnessPal or Cronometer on the side. ZON has native food-photo AI and an adaptive macro plan tied to training load. The readiness brief blends fuel and recovery in one recommendation. One subscription instead of two.
ZON- Native food-photo AI (kcal + macros)
- Adaptive macro plan tied to training load
- One subscription instead of two
Hevy- No nutrition tracking in Hevy
- Pay for MyFitnessPal or Cronometer separately
- Bodyweight tracked in two places
Community: Hevy's feed is far bigger
Hevy's feed is enormous: 13M users post into it, with a solid follow graph. ZON covers the same basics (a feed of the sessions from athletes you follow, athlete search and direct messages), but its community is much younger. If a big crowd is what keeps you training, Hevy has it.
Hevy- Massive feed with 13M+ users
- Strong follow / unfollow social graph
- Reddit-level brand recognition
ZON- Feed of the athletes you follow
- Athlete search and direct messages
- Much younger community
Make the call
Which one is for you?
Be honest about how you actually train this season.
Pick Hevy if…
The barbell is your whole world
- You only lift, and want a fast, polished, no-frills strength tracker.
- You want the cheapest possible Pro ($2.99/mo, or $74.99 lifetime which ZON doesn't offer).
- You're on Android today and need full native parity (ZON for Android is in beta).
- You want a huge community feed and Reddit-level brand recognition.
- Strava is your cardio app and you're happy with the Hevy → Strava auto-push.
Pick ZON if…
You train more than one thing
- You train more than one thing (strength + running, Hyrox, hybrid).
- You want an AI coach inside the app: post-session debrief, daily readiness, form check, mid-session copilot.
- You don't want to keep MyFitnessPal open in parallel for nutrition.
- You hate retyping a coach's PDF into a workout builder: paste a photo, get a structured program.
- You value premium production (Live Activity, share templates with a GPS overlay).
Already on Hevy? ZON's Magic Import lets you screenshot any Hevy routine and rebuild it as a ZON program in 30 seconds, no retyping. Your history doesn't move (Hevy doesn't expose an API) but your programming does.
FAQ
ZON vs Hevy, answered
Is ZON a Hevy clone?
No. ZON started from a different question: how do you build a single app for an athlete who lifts, runs, and wants an AI coach? Hevy is the best strength-only tracker; ZON optimizes for hybrid athletes who also want native AI and nutrition. Workflows, data model and AI surfaces are different.
Can I import my Hevy programs into ZON?
Yes, via Magic Import. Screenshot or photograph any Hevy routine, paste it into ZON, and Gemini rebuilds it as a structured ZON program (weeks, days, exercises, sets, schemes) in about 30 seconds.
Does ZON have a lifetime plan like Hevy?
Not currently. ZON's pricing reflects the AI cost basis: every workout runs through Gemini, every photo of food is processed by Vision, every form check video is analyzed. A lifetime plan doesn't fit that cost structure.
Is Hevy Pro cheaper than ZON Pro?
Yes. Hevy Pro starts at $2.99/month. ZON Pro costs more because it runs AI on every session (AI programs, form check, post-workout analysis), while GPS runs and nutrition come with the free app. For pure strength logging, Hevy is the cheaper option.
Does Hevy have native GPS?
No. Hevy supports duration-based cardio exercises but tracks no GPS natively. Run distance and pace live in Strava, and Hevy auto-pushes the strength workout to Strava, but the run itself doesn't sit inside the Hevy app.
Is Hevy Trainer the same as ZON's AI?
No. Hevy Trainer (launched February 2026) is an adaptive progression algorithm: it picks your next set's weight based on past performance. ZON's AI is a Gemini-powered coach: it writes a debrief paragraph after every session, generates morning readiness briefs, analyzes form-check videos, and answers questions mid-session. Different scope.
Is Hevy available on Android? Is ZON?
Hevy ships full native iOS, Android, Wear OS, Apple Watch and a web app at hevy.com. ZON is live on iOS and in beta on Android. If a finished Android app is non-negotiable today, Hevy wins on availability.
