## What is usrm?

Usrm is an app that divides your day into 1 to 4 blocks and records it in light and shade.
You can adjust each block’s title and percentage to organize today’s status, and review the last 1 week, 1 month, and 1 year in the same format.
You can share the screens you need as images, and the app supports multiple languages and basic accessibility features.
