Kaku - Kakebo

Kaku is the modern kakebo: instantly see how much you have left to spend and protect your savings—no spreadsheets required.

Kakebo is the Japanese "household account book" method: writing down expenses to build awareness. Kaku makes this process immediate, elegant, and smart.

WHY KAKU?
• Instantly see your "Available" balance for the period, not just what you’ve spent
• The period aligns with your paycheck: choose your start date (e.g., the 25th) rather than the calendar month
• Kakebo categories (Essentials, Leisure, Culture, Unexpected) with thresholds that safeguard your savings

ADD EXPENSES IN SECONDS
• Type a phrase (e.g., "coffee 2.50 leisure"), and Kaku recognizes the amount, category, and description
• Scan receipts using your camera (OCR)
• Ask Siri or use the widget to log an expense without opening the app
• Quick-action buttons learn from your most frequent expenses

MOTIVATING GOALS
• Turn savings into visual milestones with clear progress tracking
• Know exactly how much to set aside each period to reach your goals

UNDERSTAND YOUR HABITS
• Trend charts and period-over-period comparisons
• Journaling and guided reflections based on the kakebo method
• Personalized insights powered by on-device intelligence (where available)
