FAQ

Frequently asked questions

Pricing, how your data is handled, supported devices — the things worth knowing before you start.

Is it free to use?
Yes. Logging is free and unlimited — no cap on workouts or history, and no ads. There is a paid plan (Pro) that unlocks deeper analysis and higher limits on routines and custom exercises, but logging and browsing your history stay free.
What do I get with Pro?
Analysis across your full history with period comparison, unlimited routines and custom exercises, and multi-page dashboards. Pro is 350 JPY per month, 3,480 JPY per year, or 7,800 JPY once (tax included), with a 7-day free trial.
What happens to my log if I cancel?
Nothing is deleted. You return to the free plan and can still browse everything. Cancel any time from plan management in settings; Pro stays active until the end of the period you paid for.
Do I have to sign up?
No — you can start logging right away. Signing in with Google syncs and backs up your log across devices.
Where is my data stored?
While you're signed out, your log stays on that device only. Signing in stores it on the server so you can open the same log from another device.
Do I need to install an app?
No. It runs in the browser. Add it to your home screen and it behaves like an installed app (PWA).
Does it work on both phone and desktop?
Both. The screens are designed around logging on a phone, but they hold up on a wide desktop window too.
How many exercises are there? Can I add my own?
Over 400 exercises ship with the app, searchable by aliases and English names. If one is missing, add it yourself with its muscle groups, equipment, and logging format.
Can I log things other than weight × reps?
Yes. Seven formats are supported: weight × reps, reps only (bodyweight), weighted, assisted, duration, weight × duration, and distance × duration. Timed holds and cardio log the same way as everything else.
How is e1RM calculated?
With the Epley formula: weight × (1 + reps ÷ 30), applied to rep-based sets. For bodyweight-driven exercises it uses the effective load including your body weight at the time you logged.
Is there a rest timer?
Yes, and it starts on its own when you tick a set complete. Rest seconds are configurable per exercise; anything unset falls back to the global default of 90 seconds.
Can I switch between kg and lbs?
Yes, in settings. Distance can be km or mi. Data is always stored in kg and metres; units apply to display and input only.
Is there an English version?
Japanese and English are both supported, switchable in settings.
Can I export my log?
Not at the moment. If you're signed in your log lives on the server, so it survives changing devices.
