Gymex vs Strong: Which Wins in 2026?

Strong and Gymex both help you train — but they solve different problems. Strong is a logger; Gymex is a full AI strength coach. Here's an honest head-to-head on programming, coaching, price and who each one is really for.

Updated 20 July 2026 · By the Gymex team

The short answer

Strong is the better pure logger; Gymex is the better coach. Strong does one job — recording your sets — about as fast and cleanly as any app ever made. Gymex matches that logging speed (and adds voice logging on top), then does the part Strong deliberately leaves out: it writes your program, adapts it week by week, reads your reps in reserve and flags plateaus before they cost you months. If you want the app to decide your training rather than just store it, Gymex wins. If you already run a program you love and only want a flawless notebook for it, Strong is honestly excellent — and cheaper.

Who each app is really for

Strong is really for lifters who arrive with a plan. If you run 5/3/1, follow a coach's spreadsheet, or write your own periodisation, Strong is the quickest way to record it and never think about the tool again. It's also the right answer if you want the cheapest paid logger, or the most polished Apple Watch logging experience going.

Gymex is really for lifters who want a coach, not a notebook. If you don't want to design mesocycles, second-guess your working weights, or notice a plateau six weeks too late, Gymex takes that work off your plate: it writes the program, adjusts the loads from your RIR, catches stalls early and ties your training to your nutrition. The trade-off is price (from £7.50/mo vs Strong's ~£4.99); on platform they're now even, since Gymex runs on iOS and Android too.

What is Strong?

Strong is the classic minimalist workout logger — fast set entry, reliable plate-math and clean history, with excellent Apple Watch support. Its biggest strength is the cleanest, fastest logging experience in the category and a loyal, long-standing user base. The free tier limits how many routines you can save; Strong PRO (about £4.99/month) lifts those limits. What it never tries to do is coach you: every program, progression and deload decision stays with you.

What is Gymex?

Gymex is an AI strength coach for iOS that also happens to log fast. You chat with a conversational AI coach about your goals, schedule and equipment; it builds you a periodised mesocycle and adapts it weekly from your performance. Sets can be logged by voice, the weight intelligence uses your inferred RIR to adjust loads, and plateau and PR detection (across four categories) run in the background. Around the training core sit macro and meal planning with barcode scanning and a photo meal scanner, form check, 13+ body metrics with progress photos, a social feed, Garmin integration and offline support. There's a free tier, with paid plans from £7.50/month.

Side-by-side comparison

Pricing: what you actually pay

Strong is the cheaper app in absolute terms, and it's worth being straight about that. The real question is what the difference buys.

Strong PRO buys convenience: unlimited routines and the full logger. Gymex's paid plans buy the coaching layer Strong deliberately leaves out — programming, autoregulation, plateau detection and nutrition — for a fraction of what a human coach costs.

Logger vs coach: a session in each app

The cleanest way to understand the difference is to walk through a training day in each.

A session in Strong

You open the app, pick the routine you built earlier and start logging. Set entry is instant, the plate-math tells you how to load the bar, and your history is beautifully organised afterwards. When the session ends, Strong's job is done — what you lift next week, when you add weight, and when you back off are all decisions you make yourself, in your head or in a spreadsheet. That's not a flaw; it's the design. Strong is a perfect record of training you planned elsewhere.

A session in Gymex

You open the app and today's session is already written, sitting inside a multi-week mesocycle built around your goals. Each lift comes with a suggested working weight based on your recent sets and inferred RIR. Between sets you log by voice — weight, reps and how many reps you had left — without typing. If your top set came in easier than expected, next week's loads adjust upward automatically; if a lift has stalled, plateau detection flags it and the coach suggests a fix. After training you scan a barcode or photograph your meal and the macros land in the same app. Strong stores what you did; Gymex decides what you do next.

Where Strong wins

• Simplicity. If all you want is to record a program you already run, there is nothing to configure and no AI layer between you and the logbook.
• Speed of pure logging. Manual set entry is as fast as it gets, honed over years.
• Apple Watch. Strong's watch app is superb — arguably the best logging experience on the wrist.
• Maturity and track record. Strong has been refined over many years and has a huge, established user base. Gymex is the newer app — though it now matches Strong on platform reach, running on iOS and Android as well as iPad and Apple Watch.
• Price. About £4.99/month versus £7.50–£20 — Strong is the cheaper tool.

Where Gymex wins

• Programming. Gymex writes and revises your mesocycle every week; Strong expects you to bring the program.
• RIR weight intelligence. Loads adjust from your inferred reps in reserve, so the app pushes or backs off based on how sets actually felt.
• Plateau and PR detection. Stalls get flagged with suggested fixes, and PRs are caught across four categories — no manual chart-watching.
• Voice logging. Log a set mid-workout by speaking it, often faster than any manual entry.
• Nutrition. Macro and meal planning with barcode scanning and a photo meal scanner, joined up with your training.
• Coaching depth. A conversational AI coach you can question, form check, 13+ body metrics, progress photos, Garmin integration and offline support.

That's the difference between an app that records or suggests training and one that actually programs and autoregulates it for you — for a fraction of the price of a human coach.

Switching: moving your history from Strong

Strong lets you export your workout history as a CSV file from the app, and it's worth doing before you switch — keep it as an archive of every PR you've earned. The good news is you don't need that history imported to get value from Gymex: the coach calibrates to your real strength levels within your first week or two of logged sessions, because every set you record (with RIR) feeds the weight intelligence directly.

A sensible switch looks like this:

1. Export your Strong CSV as a backup.
2. Download Gymex and chat with the AI coach about your goals, schedule, equipment and current lifts.
3. Let it write your first mesocycle, then log your first week by voice so the RIR calibration is accurate.
4. After a fortnight, compare: your program now adapts itself, and your old CSV is a nice trophy cabinet rather than a tool.

Frequently asked questions

Is Gymex better than Strong?

Strong is the cleanest manual logger in the category — fast entry, reliable plate-math and a superb Apple Watch app. Gymex keeps logging equally quick (including by voice) but also writes and adapts your program, reads RIR and detects plateaus. If you want the app to decide your training, not just store it, Gymex wins.

Is Strong or Gymex cheaper?

Strong is cheaper — free with limited routines, up to about £4.99/month. Gymex is free to start with paid plans from £7.50/month; the extra buys the coaching layer Strong deliberately leaves out: programming, autoregulation and nutrition.

Is Strong better for experienced lifters with their own program?

Honestly, yes for that specific case — if you already run a proven program and just want the fastest, cleanest way to record it, Strong is superb and cheaper. Where experienced lifters move to Gymex is when self-programming becomes the bottleneck: autoregulating loads from RIR, catching plateaus early and periodising the next block is exactly what the AI coach does for you.

Does Gymex log as fast as Strong?

Manual entry is very close — Gymex is built to the same quick-tap standard between sets. Voice logging is often faster than any manual logger: say the weight, reps and RIR out loud and the set is recorded, so you never break position or put the phone down mid-workout.

Can Gymex replace a spreadsheet?

Yes — that is one of the most common switches. A spreadsheet stores numbers and leaves the maths to you; Gymex stores every set and does the maths for you: it tracks volume, infers your RIR, adjusts next week's loads, detects PRs across four categories and flags plateaus. If your spreadsheet has progression formulas, Gymex automates exactly that layer.

Can Gymex replace Strong?

For most lifters, yes — Gymex matches the fast, clean logging (and has Apple Watch support too) while adding the program Strong expects you to bring. Keep Strong only if you already run a program you love and want the simplest possible tracker for it.

What does Gymex do that Strong doesn't?

Gymex writes and adapts multi-week programs, infers Reps in Reserve to adjust your loads, detects plateaus and overtraining, logs sets by voice and tracks nutrition. Strong deliberately does none of that — it is a superb record of training you planned elsewhere.
