Boki Lens: Visual Bookkeeping

Post a journal entry, and the financial statements move in real time. Boki Lens is a hands-on accounting literacy app for people who want to understand how transactions change the income statement and balance sheet, and how cash movements connect to cash flow. When you tap a sale, expense, borrowing, or purchase, the numbers move on screen. You are not just memorizing labels. You can see where revenue, expenses, assets, liabilities, equity, and cash land. The story is simple: you open and run your own cafe. Step by step, you learn the five accounting elements, debits and credits, journal entries, financial statements, year-end adjustments, and Japan's consumption-tax basics. What you can do - Tap journal entries and see financial statements move - Learn accounting through a cafe story before technical language gets heavy - Review missed questions automatically - Complete a Year-in-Business run from opening day to closing - Read fictional industry case studies using gross margin, equity ratio, and cash flow clues Three ways to learn Learn Follow a stage-based curriculum from opening day to year-end close. All Stage 0-10 lessons are free, with no signup needed. Quiz Practice category identification, debit and credit, journal reconstruction, Year-in-Business runs, and industry case studies. Missed questions enter a review queue automatically. Journal Tap a sample transaction or enter your own. The statements at the top update live, and debit and credit tokens fly to the rows they affect. Who it's for - Sales, strategy, and leadership roles who want to read the numbers - Startup founders and small-business owners - Retail investors learning company analysis - MBA candidates warming up for accounting and finance classes - New hires in finance, operations, or business roles This is not a certification exam prep app. Boki Lens focuses on building the feel for accounting and financial statements.
