[For those worried about switching]

Changing your strength training tracking app takes courage.
"Data migration seems like a pain," "I'm afraid my records will be lost," "I don't want to have to start over again."
We often hear these concerns.

Jinrokugumi is designed to eliminate these anxieties as much as possible.

- Just one log for today is enough.
No migration process required. Simply start by recording a "Today's Record."

- Manage your past progress as well.
- All weight, repetition, and set records are organized chronologically, and 1RM and volume growth are automatically calculated.
- You'll never feel like you're starting from scratch.

- Simple, easy-to-follow UI.
- The workflow for input, comparison, and review has been thoroughly optimized to ensure a fast familiarity, even for those coming from other apps.

- Free, ad-free long-term test.
- Take your time to see if switching is right for you.

- Be proud of your records immediately after migration by sharing them on social media.
- Even your first record is converted into a beautiful shareable image that shows your growth, so it doesn't feel like you're starting from scratch.

"Learning yet another app is a pain..."
"I'm afraid to give up my current app..."
Even if you're like that, Jinrokugumi is an app that you'll naturally get used to after just one log a day.
