How we compare

Every feature checklist on this page is verified against each competitor's public website and pricing pages, and prices are checked in GBP.

TL;DR

The short answer

If you are comparing Gymex to Strong, Hevy, or MyFitnessPal, you are comparing different categories. Here is the decision in under a minute.

Pick Gymex if…

You want a single app — on iOS or Android — that writes your programs, detects plateaus, logs sets by voice, tracks macros, and stores progress photos, with AI coaching that would normally cost £150 to £300 per month with a human. Gymex is £7.50 to £20 a month, with a free tier to start.

Pick Hevy if…

You only want a free, polished cross-platform logger, and you do not need AI coaching, voice logging, nutrition, or body metrics.

Pick a human-coach service (Caliber / Future) if…

You specifically want weekly video calls, accountability texts, and a human programming for you, and you are happy paying £150 to £300 a month. Gymex is the software layer of that experience driven by AI instead.

Head to Head

Gymex versus each competitor

What each app actually does well, and when to pick it over Gymex.

Gymex vs Strong

Winner: Gymex

Strong is the classic minimalist logger — fast set entry, clean history, not much else. That simplicity is its appeal, but it stops short of everything else a serious lifter wants. Gymex includes the same fast set logging, then adds a conversational AI coach, voice logging, plateau detection, nutrition tracking, body metrics, and progress photos.

Strong is better if

  • You already have a human coach writing programs
  • You want the cheapest paid logger
  • You only need a simple logger, nothing more

Gymex wins on

  • AI programming and auto periodization
  • Voice set logging during training
  • Nutrition, body metrics, photos in one app
  • Free tier, then from £7.50/mo

Gymex vs Hevy

Winner: Gymex

Hevy is the best polished cross-platform logger. Good UX, routine sharing, free tier. The catch: it is a tracker, not a coach. Gymex — now on iOS and Android too — covers everything Hevy does plus an AI coach, voice logging, nutrition tracking, body metrics, progress photos, and Garmin integration, with a free tier and paid plans from £7.50/mo.

Hevy is better if

  • You want a free logger above all else
  • You want the biggest community-shared routines library today
  • You only need logging, nothing else

Gymex wins on

  • Conversational AI coaching and auto periodization
  • Voice set logging
  • Nutrition + body metrics + social in one app
  • Garmin integration

Gymex vs Fitbod

Winner: Gymex

Fitbod is the closest software-only comparison. It uses AI to recommend workouts and adapt to your history. But it is a solo workout engine — no conversational coach, no voice logging, no nutrition, no body metrics, no social. Gymex delivers Fitbod's core value plus everything Fitbod leaves out.

Fitbod is better if

  • You only want solo AI-recommended workouts
  • You prefer session-by-session generation over a written program
  • You prefer their specific UX and have used it for years

Gymex wins on

  • Conversational AI chat with access to your data
  • Voice logging + RIR inference
  • Nutrition, body metrics, photos, social included
  • Free tier, then from £7.50/mo

Gymex vs Caliber

Different category

Caliber pairs an app with a human coach — real people programming and checking in. Excellent for users who need accountability and a relationship, but it is priced like a trainer, not a software product. Gymex ships the software half driven by AI: programming, plateau detection, RIR inference, weekly recaps. For most lifters who just want their program sorted and their plateaus called out, the AI version is enough — and a fraction of the price.

Caliber is better if

  • You specifically want weekly video calls
  • You need a human in the loop for accountability
  • Budget is not a constraint

Gymex wins on

  • Price — from £7.50/mo vs ~£150/mo
  • Voice logging and AI RIR inference
  • Built-in nutrition and social
  • Instant responses vs wait-for-coach

Gymex vs Future

Different category

Future is a premium human-coach service priced around £199 a month. Same category as Caliber. Same reasoning applies: if you want the accountability of a human, Future is the product. If you want the software capability of a coach driven by AI, Gymex covers it for a tiny fraction of the cost.

Future is better if

  • You want accountability texts from a real coach
  • You need someone to review your form via video
  • Budget allows £199/mo on fitness

Gymex wins on

  • Price — ~95% cheaper than a human coach
  • Voice-logged sets and AI recaps on demand
  • Nutrition and body metrics built in
  • No waiting for a coach to respond

Gymex vs MyFitnessPal

Winner for lifters: Gymex

MyFitnessPal is a calorie-tracking app with the largest food database on the market. Excellent at its job, but it is only a nutrition app — no workout programming, no PR detection, no AI coaching. Gymex covers macro tracking with barcode scanning and AI meal logging plus the full strength-training stack. For lifters, it replaces MFP entirely.

MyFitnessPal is better if

  • You only want calorie tracking, no training features
  • You need the largest food database for obscure products
  • You want a dedicated calorie tracker rather than a training app

Gymex wins on

  • Single-app experience for training + nutrition
  • AI meal logging from natural language
  • Strength analytics MFP cannot produce
  • Free tier, then from £7.50/mo

FAQ

Common comparison questions

The questions lifters ask when deciding between these apps.

Is Gymex a better alternative to Hevy or Strong?
Gymex and Hevy/Strong sit in different categories. Strong and Hevy are manual loggers. Gymex is AI coaching software that also logs — it writes programs, detects plateaus, infers RIR, logs sets by voice, and tracks nutrition. If you want more than a logger, pick Gymex. If you only want the cheapest cross-platform logger, Hevy is a good choice.
Is Gymex cheaper than Caliber or Future?
Yes, by a large margin. Caliber and Future are £150 to £300 per month because they include a human coach. Gymex delivers the software layer driven by AI for £7.50 to £20 per month, with a free tier to start.
Does Gymex replace MyFitnessPal for nutrition tracking?
For most lifters, yes. Gymex tracks macros with barcode scanning, AI meal logging from natural-language descriptions, meal-type assignment, and visual progress rings. It also adds the full strength-training stack that MyFitnessPal does not have. If you need an extremely niche food database and do not lift, MFP may still be the right choice.
Is Fitbod or Gymex better for AI-generated workouts?
Both generate workouts with AI. Gymex adds a conversational coach you can chat with about your training, voice logging, plateau detection, nutrition, and social. Fitbod is narrower — solo AI-recommended workouts without those layers.
Which workout app has Garmin integration?
Of the apps in this comparison, Gymex is the only strength-training app with native Garmin pairing. Pair via a 6-digit code for activity sync. Gymex also reads from Apple Health. Strong, Hevy, Fitbod, Caliber, and Future do not include Garmin pairing.
Is Gymex available on Android?
Yes. Gymex is now on Android via Google Play, as well as iOS for iPhone and iPad. Both versions share the same features, pricing, and account sync, so Android lifters get the full AI coaching, voice logging, nutrition, and body-metrics stack.
Does Gymex have a free tier?
Yes. The free tier includes workout logging, nutrition tracking, body metrics, basic progress photos, community, messaging, manual program building, Garmin pairing, and offline sync, with a 30-day history window. Paid plans are Core £7.50 per month, Premium £15 per month, and Pro Premium £20 per month, with a 17% discount on annual billing.
I use Strong plus MyFitnessPal plus a photo app. Does Gymex replace all three?
Yes. That stack is exactly the problem Gymex is built to solve. Workout logging, macro and barcode tracking, and body measurements with progress photos are all first-class features in the same app. Most lifters can retire MFP and a photo app on day one.
