The gym workout tracker that knows when you’re cooked
A free gym workout tracker with no account. Log every set, and see what it’s doing to you — per-muscle recovery, training load and systemic fatigue, before you stall.
Out now on iPhone and Apple Watch. No email, no account, no “sign in to continue” — that part never changes. Android’s next.
Track training load and systemic fatigue
Eight weeks of strength, cardio and stretch volume, with the overall trend running behind it.
Training Load
Last 8 weeks
See which muscles have recovered before you train
One strength score built from every set you log, and the tier it lands you in.
Muscle Profile
See what PRO sees
The free app records your training. These are the screens that tell you what it’s doing to you.
A 6-axis view of what you’ve delivered this cycle.
Readiness for every muscle, so you know what’s recovered before you get under the bar.
Know when each muscle group is ready to train
A workout planner that builds your week and loops it
Build a week, set it to repeat — and the coach checks it against what you actually lift.

Suggestions
Last session felt easy — weight increased by ~5% for progressive overload.
Increase chest volume — your strength is progressing faster than your plan.
Muscle Stimulus
An AI workout coach that has seen your training Beta
I look at your actual training — what you lifted, how recovered you are, where your plan is going. Try:
- Am I recovered enough to train legs?
- Should I add weight to my bench?
- Am I overtraining?
- Is my program balanced?

Why an AI chatbot can’t plan your training
Ask any assistant whether you should add weight to your bench and it has to guess — it’s never seen you train. GymHack’s coach is handed your measured training state first, then your question.
It reads your numbers, it doesn’t guess them
The figures it works from are computed by the app’s own engines and handed over with every message. Log nothing and the briefing says so outright, and forbids it from naming a session, a weight or a streak you never had.
It edits your plan, it doesn’t describe one
17 kinds of plan edit and 29 things it can do in the app — swap an exercise, change sets, add a warm-up, build a superset, schedule a rest day. Every plan edit is checked against your actual week and the 430+ exercise database before you see it.
It would rather stop than guess
Ask it to swap in something called just ‘leg’ and you get nothing back — Leg Curl and Leg Press both match, so it means neither. If your message doesn’t say which session you meant and the exercise sits in more than one that week, it declines too. And nothing changes until you tap the card.
Free, and actually free — a gym log with no caps
Not a trial of the real app. This is the app.
Workouts, sets, supersets, rest timers, per-set RPE, drop sets, warm-up and failure sets. No caps on how much you train.
Images, instructions, coaching cues and muscle maps. Plus your own custom exercises and gym machines.
Build a weekly plan yourself or generate one. Periodisation phases coach you mid-session — deload, volume and intensity guidance.
Volume, max weight, estimated 1RM and your full PB history for every movement. Plus guided 1RM testing.
Running, cycling, rowing, walking, stair climber and interval sessions. Add an Apple Watch or Wear OS watch for live 5-zone heart-rate training.
Send a plan or template to your training partner with a six-character code. They don’t need an account to open it.
Built for your gym, not a generic one
Yours has that one plate-loaded machine no one else stocks. Add it — and your AI Coach will program around it.
The whole watch app. Both platforms. Free.
Apple Watch and Wear OS. Most trackers put the watch behind a subscription — we don’t gate it at all.
Logging tells you what you lifted. PRO tells you what it cost.
The free app records your training. PRO models what it’s doing to your body — and the 14-day trial opens every PRO feature.
