Penny

Penny is a personal budget app. Connect your bank and investment accounts (or add them by hand), and it turns your transactions into a clear picture of where your money goes — spending by category, trips, investments, and how this month compares to your own history.

Try it

No sign-up needed — there's a public demo account:

• App: penny-blue.vercel.app
• Email: [email protected]
• Password: u9LRuZGSDAw7mF4LkSQG

It comes preloaded with sample transactions (new ones are added each day, so the current month is never empty), a trip, and a reimbursement, so every page has something to look at right away. Everything works except linking a real bank, which is turned off for this account.

What you can do

• Overview — see what you've spent, earned, and saved this month (or the last 12), broken down by category in a chart. This month is compared against last month, the same month last year, and projected to where it'll land based on your own habits.
• Transactions — search and filter your activity, add one by hand, or import a CSV from your bank. New transactions are categorized automatically. Attach a payment someone sent you back to the expense it covered, so what you see reflects what you actually paid.
• Trips — group travel spending together. Attach transactions to a trip and they're filed under Travel; a friend paying you back for their share nets against the total automatically.
• Year — every category, every month, laid out in one table.
• Investments — connect a brokerage to see your holdings, what they're worth, and your gain or loss, plus how much you've contributed over time.
• Accounts — connect a bank, or add one by hand if it won't link. Rename or close an account without losing its history.
