Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Type "lunch 1200, snacks 300" and AI logs it, category and all. A home-screen widget shows what's left this month. Share with your partner or family to budget together.
Just type it, and your budget takes care of itself.
Purumu is a simple household budget app where AI helps you log your spending. See at a glance how much you have left this month, and share your budget with your partner or family. If you've given up on budgeting before, this could be the time it sticks.
■ Just type it — AI logs it for you
Enter several expenses at once in everyday words, like "lunch 1200, snacks 300." AI reads the amount, category and date, and turns them into entries. You can also switch to manual entry and pick the amount and category yourself.
■ See what's left this month
Set a monthly budget and check what you've spent and what's left at any time. The list and calendar views show when and where your money went.
■ Home-screen widgets
Check this month's remaining budget and daily trend without opening the app. One tap opens the entry screen.
■ Spot overspending with charts
・6-month spending trend
・Daily running total compared with last month
・Spending and share by category
・How money flows from income to expenses
Even if numbers aren't your thing, the charts show how your spending is changing.
■ Monthly AI advice (Premium)
AI reads how your spending changes and sends money-saving tips that fit your household.
■ Share with your partner or family
Send an invite link and keep one budget together. Set roles for each member: admin, editor or viewer. You can also keep separate workspaces, for example one for living costs and one for travel.
■ Log from LINE, too
Send a message to the LINE official account and it's recorded in the same budget as the app. Using it in a LINE group with your family works well, too.

・Have given up on budgeting before
