* Key Features
1. Group vs One‑time Event
- Register participants once for a group and reuse them across multiple events.
- For one‑time events, you can directly add participants only for that day.
2. Event Registration
- Group event: Select group → optional memo → date → choose participants.
- One‑time event: Enter event name → optional memo → date → add participants.
3. Event Editing (In Progress)
- Before settlement is completed, you can edit memo, date, and participants.
- Event type and name (group/event name) cannot be changed.
4. Expenses & Settlement
- Record total amount, payer, and participants, categorized (café, meal, shopping, hobby, sports, beauty, travel, others).
- Saved expenses display the category along with the entered date and time.
5. Expense Screen
- In event details, tapping a participant shows a modal with their name and phone number.
- In the expense list, you can toggle participant display On/Off. When On, participants appear in one line and are also reflected in the settlement preview.
6. Receipts
- Attach receipt photos to expenses for later review.
7. Settlement Sharing
- Copy settlement details, or on Android, send the same text to multiple participants via SMS.
8. App Lock
