Hevy vs Saga: Modern social tracker vs AI coaching
Hevy and Saga overlap more than it might seem: both let you build routines and log your workouts cleanly. The difference is what each adds on top. Saga adds an AI coach that writes a workout plan from your goal and adapts it as you train. Hevy adds a social feed for following friends, and it costs less. So the real question is whether you want coaching or a social layer.
Pick Saga if you want a coach that authors and adapts the plan around a goal.
Pick Hevy if you self-coach, want a social feed and a lower price, or you're on Android or web.
| Feature | Saga | Hevy |
|---|---|---|
| AI coach | An AI coach that writes the plan against your SMART goal and adapts it as you log. Chat is there when you want reasoning, a substitution, or a plain-language change. | No conversational coach. Hevy Trainer adds algorithmic programming and auto-progression, alongside a logger and social feed. |
| Workout generation | Writes a plan around your SMART goal, equipment, and schedule. You can also build and log your own routines. | Bring or build routines, use the community library, or auto-generate a program with Hevy Trainer. |
| Plan adaptation | Plan adapts as you log; edit by hand and the algorithm picks up. Chat the coach when you want a bigger structural change in plain language. | Hevy Trainer auto-progresses load from your logs; routines are otherwise edited manually. |
| Exercise substitution | One-tap quick-swap from a filtered list, or ask the coach in chat for reasoning. | Manual swap from the database. |
| Schedule changes | See the schedule for your whole training program, not just the next workout. Edit it by hand, or ask the AI coach for one-time changes (travel, illness) or recurring ones (a new weekly routine). Saga also auto-updates the schedule after a missed workout. | Edit your routine manually. |
| Free tier | Three free workouts plus a 7-day free trial. | Genuinely strong free tier. Much of the core logger is free. |
| Pricing | $12.99/month or $79.99/year, with 1 week free. | Free tier; Hevy Pro is $2.99/month or $23.99/year |

Where Saga is stronger
Programming is the clearest difference. Hevy Trainer can now generate a program and auto-progress load, but it builds from templates and equipment inputs rather than a long-term measurable goal. Saga authors a plan against the specific goal you set, can walk you through the reasoning, and restructures it in plain-language chat as you train. That matters most for trainees whose main question is "what should I actually be doing," and why.
The other difference is where you get answers. In Hevy, you ask your friends in the social feed, which is great for motivation but not built for programming questions. Saga's coach is, and you can ask it directly.
Where Saga falls short
- No Android or web today; Saga is iOS and Apple Watch only.
- No social feed; Saga is 1:1 with the coach.
Where Hevy is stronger
Hevy has two clear advantages over Saga. The first is the social feed: you can follow friends, see their workouts, and comment on PRs, which keeps a lot of people consistent. Saga has nothing like it. The second is price: Hevy Pro is a few dollars a month, well below Saga, and the free tier is genuinely usable. The logging itself is clean and fast, with well-designed history and an intuitive routine builder. For lifters who want an affordable tracker with a social layer, Hevy is a strong choice.
Frequently asked questions
Is Saga a good Hevy alternative?
Yes, if you want an AI coach rather than a self-coached tracker. Saga builds and adapts your plan, and you can still log and build your own. Hevy's edge is its social feed, lower price, and Android and web apps.
Can I switch from Hevy to Saga?
Yes. Open Saga, set your SMART goal, and the coach builds a plan in minutes. If you've been running a routine in Hevy, share it in chat and the coach factors it into your plan.
Does Hevy use AI?
Hevy now ships Hevy Trainer, an algorithmic program generator with auto-progression, plus a logger and social feed. Neither is a conversational coach you can ask questions and get adaptive reasoning from. That's Saga's role in this comparison.
Does Saga have a social feed?
No. Saga is built around the 1:1 coach relationship. If a social layer matters to you, Hevy is meaningfully better on that dimension.
Can Saga log as fast as Hevy?
Saga's logging is solid for everyday use, but Hevy's logger has been refined since 2019 and logging is its core focus. For high-volume power loggers, Hevy is the smoother experience.
