Comparison
Swole Protocol vs Hevy
Hevy is one of the best tap-to-log workout trackers around — polished app, big exercise library, a social feed for training with friends. Swole Protocol plays a different game: it's the training memory your AI plugs into. If your coaching conversation already happens with Claude or ChatGPT, here's how the two compare.
Side by side
| Hevy | Swole Protocol | |
|---|---|---|
| How you log | Open the app, tap through exercises, sets and reps. | Tell your AI in plain English — “bench 100kg 3x5” — mid-chat, mid-workout. |
| AI coaching | Not built in. Your AI can't see your Hevy history. | The whole point: Claude, ChatGPT or any MCP client reads your goals, program, history and PRs. |
| Programs | Pick or build routines inside the app. | Your AI writes the block; Swole Protocol stores it and tracks every session against it. |
| Cardio | Logged in the app alongside lifting. | First-class: runs, rides and rows with distance, time and pace — next to your sets. |
| Where it works | iOS and Android app, watch support. | Anywhere your AI runs — phone, desktop, even the terminal. No extra app. |
| Price | Free tier with limits, paid Pro subscription. | First 50 workouts free, then $15 a year. |
Pick Hevy if…
- You want a polished standalone mobile app with a dedicated logging UI.
- The social side matters — following friends and sharing workouts.
- You'd rather tap through a familiar app than have an AI in the loop.
Pick Swole Protocol if…
- You already talk to Claude or ChatGPT about training and are tired of re-explaining your history every chat.
- You want coaching grounded in your actual numbers — PRs, e1RMs, last month's sessions.
- You train lifts and cardio and want one memory for both.
- You don't want another app. Your AI is the interface.
The short version
Hevy is a better app. Swole Protocol isn't trying to be an app at all — it's the memory that makes your AI a real coach. If AI is already part of how you train, that trade is the entire point.
Questions, answered
Is Swole Protocol a Hevy alternative?
Yes, if what you want from Hevy is workout tracking. Swole Protocol tracks sets, cardio, bodyweight and PRs like a traditional tracker — but you log by talking to Claude, ChatGPT or any MCP client, and your AI can read your full history to coach you. If you mainly want Hevy's social feed and app UI, Hevy remains the better fit.
Can I use Swole Protocol and Hevy together?
Nothing stops you, but the value of Swole Protocol is having one source of truth your AI can see. Split your logs across two trackers and your AI only knows half the story.
Does Swole Protocol have a mobile app?
No, by design. It lives behind your AI — so the Claude or ChatGPT app you already have is the interface at the gym. Log between sets by voice or a one-line message.
How much does Swole Protocol cost compared to Hevy Pro?
Swole Protocol is free for your first 50 logged workouts, then $15 per year. Hevy offers a free tier with limits and a paid Pro subscription — check hevy.com for their current pricing.
