Each month is a card. Add income and expense lines (a category and an amount); the card shows the totals and net, and the summary up top rolls everything together with a spending breakdown.

It creates the next month already pre-filled with last month’s lines — your rent, salary and EMIs are recurring, so you just adjust what changed instead of retyping everything.

Big one-off items that aren’t part of a normal month — a bonus, a trip, an annual insurance premium. They’re tracked separately so they don’t distort your monthly numbers.
