3 reasons people pick this app

It is more than a metronome. Everything you need to keep going is built in.

01

Exact tempo,
guided by voice

Set the seconds for lifting, lowering and pausing per exercise. Voice and beeps keep the rhythm so you never count. One-side-at-a-time exercises switch automatically.

02

Logs that build
themselves

Every workout is saved the moment it ends: sets, reps and weight, with a stamp on the calendar. Streaks and monthly summaries show at a glance whether you are keeping it up.

03

See your
progress in data

Reps and max weight per exercise over time, plus charts of weight, body fat and muscle mass. Draw a goal line and watch the change happen.

Everything you need, in one app

All the tools for training, without switching apps.

Tempo timer

Voice and beeps guide an exact tempo. Holds, one side at a time and timed work are all supported.

Workout log

Sets, reps and weight are recorded automatically, with a comparison to last time on the spot.

Weight & body composition

See how your body changes and stay motivated. Goal lines included.

AI Coach: your week, planned Coming soon

Figuring out what to do is the number one reason people quit. The coach builds a week of workouts from a short questionnaire and your logs, and revises it every week.

The AI Coach and the exercise library are in preparation and planned for the next update. The details below describe the planned release; pricing and terms may change.

💪 Building muscle

Rotates chest, back and legs so the same muscles never work two days in a row. If your numbers went up, next week gets a little heavier; if not, it stays.

🔥 Losing fat

Higher reps plus cardio every session. Losing weight too fast? It holds the load this week. Losing muscle? It suggests protein and rest.

🚶 Staying mobile

A light circuit that alternates easy strength moves and marching in 30-second rounds. Once a week is fine, and so is starting in your 60s; it adjusts to your age group.

  1. Answer a few questions: goal, intensity, days per week, time, experience, equipment, areas to avoid. Age group is optional.
  2. Get a plan: sets are registered to weekdays automatically, with warm-up and cool-down stretches matched to that day's muscles.
  3. Just do it: before each exercise a picture and a cue are shown and read aloud. You can check the movement on YouTube.
  4. Weekly review: rebuilt from last week's logs and your weight and muscle trend. Requests like "make it shorter" are applied on the spot.
Planned as a monthly subscription (about ¥300 / month, local price shown on Google Play) with the first 7 days free (cancel during the trial and you pay nothing). Subscribers get every Pro feature too. If you cancel, your plans, sets and logs stay. A one-time Pro purchase without AI is also available.
Plans are general exercise guidance, not medical advice. A summary of your answers and logs is sent to the AI only to build the plan and is not stored on the server.

How many was that?
You never have to count again.

The app keeps the seconds and the reps.
You keep your form.

"Four seconds up, two seconds down." Slowing the tempo makes the same weight harder. Leave the counting to the app and focus on your form.

Why I built it

This did not start as an idea for an app. It started as a problem I had.

I wanted more load without buying heavier dumbbells

Training at home, my dumbbells had become too light, but not light enough to justify buying heavier ones. Then I learned that slowing the tempo of each rep raises the load. When I tried it, I could not keep count: reps, seconds and form all at once. The counting got in the way and my form got sloppy. A timer that counts the tempo for me: that was the starting point.

Once I started, the wish list kept growing

Count each arm separately. Pause mid-rep. Then intervals, sets, a weekly schedule, a log of what I did, body weight. The tempo timer became a tool for keeping up training.

I use it every single workout

I still train at a fixed tempo with this app every time. When it gets hard and the voice says "three left" and "last one", I push a little more.

Any exercise, your own names, and no guessing

It is faster to register the exercises you actually do, under the names you use, so entry is free-form. For people who told me "I don't know what to do", an illustrated exercise library and an AI coach that plans your week are on the way.
