Plan the workout
Create structured training plans, organise workouts and exercises, and keep targets and notes available before the session starts.
Available on iPhone
A gym workout tracker that connects the whole session.
MuscleMetric is a gym workout tracker app for iPhone built around one connected training record. Plan the workout, log sets, reps and weight while you train, keep completed sessions in your workout history, and use that history to understand strength and training progress over time.
One training record
A workout tracker should still be useful after the workout ends.
Many people start with notes, a spreadsheet or a basic set counter. Those tools can record numbers, but the useful part is what happens next: finding the previous session, comparing an exercise, checking whether training frequency is consistent, and seeing whether a goal is actually moving.
MuscleMetric keeps planning, live workout logging, training history and progress analysis connected. A planned session becomes the workout you perform, the sets you complete become history, and that history feeds the progress views you use later.
Log sets quickly
Record completed reps, weight, time or distance set by set without turning the gym session into admin.
Review progress
Use workout history, exercise performance, volume, frequency and goals to understand how your training is changing.
Strength and hypertrophy training
Built for people who want more than a simple set counter.
For strength training and hypertrophy work, the important numbers are usually simple: what exercise you performed, how many sets and reps you completed, the weight used, and how that compares with previous sessions. MuscleMetric keeps those basics quick to record while preserving enough context to make the history useful.
That makes MuscleMetric useful as a strength training tracker, weight-lifting log and general gym workout tracker without forcing every type of training into exactly the same format. Weight-and-rep exercises can sit alongside timed or distance-based work in the same training system.
Strength sessions
Keep working sets, reps, weight, previous performance and long-term goals connected to the same exercise history.
Hypertrophy sessions
Track repeated sets and rep ranges while keeping weekly training, volume and exercise history visible over time.
Mixed gym training
Combine resistance training with timed or distance-based exercises without needing a separate log for each format.
What to look for
What makes a useful workout tracker app?
A good workout tracker should reduce friction during the session and increase clarity afterwards. For MuscleMetric, that means four things: the next workout is easy to understand, logging is fast enough to use every session, completed training stays available as history, and progress views remain tied to the actual workouts that produced them.
Fast during training
You should be able to record a set in seconds and get back to training rather than navigating through unnecessary screens.
Historical context
A number is more useful when you can see the session, exercise and previous performances around it.
Understandable progress
Training trends should be explainable through completed sessions, volume, frequency, exercise performance and goals rather than an unexplained score.
