About this app

Kinrokugumi is a workout tracking app that automatically calculates "training volume" (weight x reps x sets) and thoroughly supports the "principle of progressive overload," which is key to muscle hypertrophy.

With no ads, simple operation, and easy-to-understand graphs, it accurately quantifies your efforts. More than just a record-keeping notebook, it's an aggressive logging app specifically designed to visualize "how you surpass your previous self."


[Home Screen: See Volume Accumulation at a Glance]
- Intuitively grasp training frequency with a weekly calendar.
- Clearly visualize long-term growth with a 1RM trend graph for the entire period.
- Real-time aggregation of today's total training volume, maximum weight, and number of sets.
- Share with a single button. Smooth reporting on social media.


[Record Screen: Don't Miss the Volume Difference from Last Time]
- Smoothly record weight, reps, and notes for each set.
- The "Compare to Previous Time" function allows you to compare volume and weight with the previous time while inputting.
- Your best training partner, helping you push yourself without hesitation. [Reporting Function: Multifaceted Training Analysis on a Weekly and Monthly Basis]
- Automatically reports on total volume trends and training days in weekly and monthly summaries.
- Directly informs improvements to next month's training plan, such as "I didn't do enough back volume this month."

[Weight Management: Recording the Foundation of Your Training]
- Visualize daily weight changes in graphs to accurately understand changes in your body.
- Objectively analyze muscle hypertrophy progress by comparing training volume and weight changes.
- Simple and easy-to-use input design useful for managing bulking and cutting phases.

[For Those Considering Switching: Start with Today's Log]
- Designed to alleviate concerns such as "It's a waste of data from my current app" and "Migrating is a hassle."
- No migration required: Simply record today's data, and a growth graph will be automatically generated.
- Automatic import using AI: Upload screenshots or photos of past records to automatically import past data.
