幹事くん - 集金・割り勘・レシート管理

This app allows you to smartly manage finances for events like drinking parties, trips, and lunch gatherings.

■ Collection Management
Records collection history for each participant. See at a glance how much was received and how much is still needed. The collected amount flag makes it easy to identify those who haven't paid.

■ Automatic Bill Splitting
Automatically calculates the amount each person pays simply by registering the receipt. Supports equal splitting for everyone, as well as individual allocation (e.g., "this dish is for this person only"). Fractional amounts are automatically tallied as the organizer's responsibility, ensuring accurate calculations.

■ Receipt Management
Save receipts as photos. Simply take a picture with your camera or select from your gallery.

■ Participant Registration (Global Management)
Pre-register your frequent drinking buddies and add them with a single tap for future events.

■ Sharing Results
Send results to participants via LINE or email. Flexible sharing options include individual contributions, collected amounts, and differences.

■ JSON Export/Import
Export and import data as JSON files. You can rest assured even if you change your smartphone.
