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)
DESIGNED FOR THE APPLE ECOSYSTEM
• Apple Watch app and watch face complications
• Home Screen and Lock Screen widgets
• Siri Shortcuts and App Intents
• iCloud synchronization across your devices
• Family Kakebo: share expenses and plans with your partner
PRIVACY FIRST
Your data stays yours: it lives on your device and in your private iCloud. No tracking, no ads, and no third-party accounts.
Download Kaku and take back control of your money, one day at a time.
