PiggySpy turns tracking your money into detective work โ€” and it stays out of your way while doing it. ADD AN EXPENSE IN THREE TAPS A numeric keypad with a built-in calculator. Type 12+8, pick a category, done. SEE WHERE IT GOES A donut chart by category for any period: day, week, month, year or a custom range. Charts for spending over time, income against expenses and money flow. A REPORT THAT WATCHES THE MONTH A month-end forecast, a comparison with your typical month and your spending pace. Categories that stray from the usual stand out at once โ€” and any category can carry a monthly limit. SAVINGS, KEPT SEPARATE Mark a category as savings โ€” bonds or a deposit stop counting as spending and get their own place on the home screen, in the report and on the charts. SHARE AN ACCOUNT Run a household budget with someone else. Both of you see and add entries on the same account, using the same categories, so the totals always agree. Your other accounts stay private. BRING YOUR HISTORY WITH YOU Import a CSV from another app โ€” PiggySpy proposes the column mapping and creates missing categories. Export back to CSV or paste straight into a spreadsheet. MADE FOR EVERY DAY Multiple accounts. Recurring payments added automatically. Face ID lock. Themes and colours you can adjust. Available in English, Polish, German, Spanish, French, Italian, Portuguese, Japanese and Chinese. YOUR DATA IS YOURS Everything lives on your device and in your private iCloud. There is no PiggySpy server, no account to create, no ads and no tracking. We cannot see your finances โ€” nobody can. FREE, WITH AN OPTIONAL TIP Every feature above is free forever. If PiggySpy earns its keep, you can support it โ€” supporters get an alternate app icon, True Black mode, extra themes and shared accounts.
