## What is 31Log?

Capture every change in a single time-lapse video.

A specialized recording app to "fixed-point observe" small daily growth and changes, and compile your 31-day journey into one video.

Support for your 31-day challenge: A 31-day recording cycle makes it easy to set a "one-month" goal. Your daily progress remains visible and tangible.

Progress management with Calendar: Equipped with a calendar view to see your shooting status at a glance. Helps you keep recording daily with joy and consistency.

Swipe-to-review Log: Photos can be reviewed intuitively like a flipbook with swipe gestures. Feel the process of change firsthand.

One-tap Video Generation: Once your 31-day record is complete, export a high-quality time-lapse video with a single button. Perfect for SNS sharing or personal growth logs.

Plant growth, fitness body changes, diet progress, or the daily sky. Save your "31-day story" as a special video.
