Structure your training.Measure your progress.
JYMI is the strength training tracker that turns your workouts into useful data — so you know what you're doing, understand what's working, and gradually make better decisions about what to do next.
From planning to execution
Every session counts.
JYMI remembers it.
Because a good tracker shouldn't just log what you did.
It should turn your history into insights that move you toward your goals.
01 — Planning
Build it once.
Progress all year.
Structure your sessions across weeks or months and set up your recurrences.
- Custom recurrence for every session
- Unlimited session planning
- Daily reminder to train
02 — Session Building
The right exercise. Not another one.
Your stats finally tell the truth.
Over 1,100 exercises and smart search. Find your exercise in seconds.
Reliable data starts with correctly logged sessions.
- 1,100+ exercises. Everything you do at the gym.
- Smart search. Type it, find it.
- Advanced methods. Tempo, supersets, drop sets.
03 — Live Tracking
More than a workout tracker,
JYMI optimizes tracking during your session.
JYMI guides you through the effort: live tempo, left/right tracking, RIR after every set, and automatic superset chaining.
- Live tempo gauge, phase by phase
- Separate left/right tracking on unilateral movements
- RIR logged at the end of every set
- Supersets chained automatically
04 — Performance Analysis
Data that's useful
and actionable.
JYMI doesn't just measure the usual metrics. We chose to go further and process that data into concrete action you can apply to your training.
- Session intensity heat map
- Muscle engagement ratio
- Automatic personal record detection
- Time under tension, broken down by tempo phase
05 — Readiness
Other apps don't factor in how you feel today.
JYMI does.
A daily, few-second check-in lets JYMI understand your current state and suggest smart adjustments to today's session.
- Daily readiness
- Readiness score based on sleep, physical state, mental state, and nervous system status
- Readiness history and long-term analysis
06 — Nervous System Check
A 20-second daily test
to read your nervous system.
In 20 seconds, the tap test measures your tapping speed — left hand, then right — and compares it to your own baseline.
- Baseline built from your own history
- Cross-referenced with your self-reported readiness
- An objective signal to better understand how you're doing today
07 — Share Your Wins
Be proud of your effort.
Share it with your friends.
With one tap, turn your data into a visual built to be shared — and to motivate the people around you.
Friends want to try your workout? Share it in one click.
- Intensity heat map generated from your RIR
- PNG export optimized for Instagram stories

Why JYMI
The more you train,
the more useful JYMI becomes.
Most trackers know how to log a session.
JYMI wants to go further: keep your history, cross-reference your data, and gradually turn what you do into insights for your next decisions.
Your training builds your data.
Your data builds your next training.
A history that remembers.
Every exercise, every set, every RIR, every tempo, and every readiness check enriches your history.
Not to fill up charts.
To build an increasingly precise view of your progress over time.
Beyond how you feel.
How you feel matters. But it's not the only signal.
JYMI combines your training data with your daily readiness to help you make more informed decisions, instead of starting from scratch every time.
Built for serious lifters.
No ads. No social feed. No pointless gamification.
JYMI is built like a real training tool: fast during your session, precise with data, and simple enough to disappear when you need to focus on your set.
Your next training block deserves better
than a simple history.
JYMI is launching soon on iOS and Android.
Structure your sessions. Measure your progress. Build your history.
And let your data become progressively more useful.
