Workout trackers for AI-assisted training
This page compares workout trackers on one axis: how much your own AI assistant can actually do with your training data. It is written by the MyoAmigo team, so read it as an interested party's comparison. MyoAmigo's column comes from our own code; competitor details come from their public sites and docs as of August 2026 and may have changed since, so check theirs before deciding.
Honesty first: Hevy and Strong are excellent loggers with far larger communities than MyoAmigo. Hevy runs on Android and the web and has a real social feed; Strong has years of polish and trust. If you want a popular, social, cross-platform logger, they are safe picks. The one thing we claim is the AI-integration column: MyoAmigo is a local-first iOS strength-training tracker with Apple Watch logging and an MCP server that lets AI assistants like Claude read and coach your training.
The incumbents: Hevy and Strong
| MyoAmigo | Hevy | Strong | |
|---|---|---|---|
| MCP server (assistant API) | Yes, first-party and hosted: 45 account-scoped tools at api.myoamigo.com/mcp | No first-party MCP. Community-built Hevy MCP servers exist; they describe themselves as unaffiliated with Hevy and say they require a Hevy PRO API key. | None advertised that we could find. |
| Assistant can read your training | Yes: history, PRs, e1RM trends, muscle-balance volume, stalls, standards, week review (20 read tools) | Partly, first-party: HevyGPT (a ChatGPT custom GPT) can analyze training history with an active integration, per Hevy's HevyGPT page. Other assistants only via the community projects. | Not that we know of. |
| Assistant can write (routines / plans / sets) | Yes: 25 write tools (create/revise routines and weekly plans, log sets and cardio, corrections) | Routine import via HevyGPT (Hevy's page notes free accounts are limited to four routines); set logging and broader writes only via the community projects. | Not that we know of. |
| Muscle-balance analytics exposed to assistants | Yes: weekly sets per muscle vs evidence-based bands, readable over MCP | Its analytics live in-app. | Its analytics live in-app. |
| Apple Watch logging | Full standalone cockpit: crown reps, rest ring, per-set heart rate, works without the phone | Companion watch app; its App Store page describes live sync with the phone and saving "when reconnecting to iPhone". | Watch app available. |
| Social features | None | Yes: feed, friends, likes | Sharing only; no social feed advertised. |
| Android | No (iPhone + Apple Watch; web app at app.myoamigo.com) | Yes | Yes |
| Price | Free to log/sync/keep history; Pro $39.99/yr, $5.99/mo, or $49.99 lifetime | Free tier + Hevy Pro; its App Store listing shows $2.99/mo, $23.99/yr, and $74.99 lifetime (Aug 2026). | Free tier + Strong Pro; its App Store listing shows $4.99/mo, yearly from $23.99, and lifetime from $79.99 (Aug 2026). |
The AI-native trackers
A newer group of trackers is built around assistant integration the same way MyoAmigo is. These are small products moving fast; the notes below reflect their public docs as of August 2026.
| MyoAmigo | Arvo | Tally Workout | Liftosaur | |
|---|---|---|---|---|
| MCP server | First-party, hosted, 45 tools; OAuth 2.1 or API key | First-party, open source (arvo-mcp), 29 tools; auth via a personal API key, per its developer docs | First-party hosted Claude connector per its site; its App Store page notes it requires a paid Claude plan with custom-connector support | First-party, OAuth 2.1 or API key; requires its premium subscription per its docs |
| Assistant read + write | Read history/PRs/muscle balance/stalls/standards; write sets, cardio, routines, weekly plans, corrections | Read history/PRs/measurements; write workouts, sets, PRs, plans, per its docs | Read history; write planned workouts into the app, per its site | Writes programs in its own scripting language (Liftoscript), per its docs |
| Coaching analytics exposed to assistants | Muscle-balance volume vs evidence-based bands, stall detection with prescriptions, strength standards, week review | Not detailed in the docs we've seen | Not detailed in the docs we've seen | Not detailed in the docs we've seen |
| Apple Watch | Full standalone cockpit (crown reps, rest ring, per-set heart rate) | Yes; its App Store page lists watchOS support | No watch app listed on its App Store page | Not stated in the docs we've seen |
| Platforms | iPhone, Apple Watch, web | iOS, Android | iPhone (Android announced) | Not stated on its MCP docs page |
| Local-first / offline, no account required | Yes; sync optional, no ads or trackers | Requires an Arvo account; no offline claim in its docs | Its site says free, no ads, works offline | Not stated in the docs we've seen |
Also in the neighborhood: Tredict (first-party MCP, endurance sports rather than strength), Strava's first-party read-only MCP connector, INCREMNT (iPhone + Apple Watch; ships an npm-published CLI, and lists MCP as a capability without published endpoint or docs), and LiftTrack (first-party ChatGPT/Claude/Cursor/Gemini connection per its App Store page, though its docs never name MCP or publish an endpoint).
Choose them if / choose us if
Choose Hevy if you train with friends and the feed keeps you going, you're on Android, or you want a generous free logger with a big community. Those are real advantages MyoAmigo doesn't have.
Choose Strong if you want a minimal, proven logger you already trust and don't care about AI integration. (If you switch later, MyoAmigo imports Strong CSV losslessly.)
Choose MyoAmigo if you use an AI assistant and want it working from your real numbers: reading your history, PRs, and muscle balance, and writing next week's plan back into the app you log with. That loop, first-party and supported, is the product.
