Lumi - Instant Expenses

Log expenses fast, ask Lumi where your money went, and understand your month without accounts, ads, or bank links.

Most expense apps fail because logging is too slow. Lumi is built for fast daily expense entry on iPhone: type quick notes, save one-off expenses, ask Lumi where your money went, track subscriptions and fixed installment debts, and review simple current-month reports.

Your data stays on your device. Lumi does not require an account, does not show ads, and does not connect to your bank. Choose one setup currency, then keep spending records simple, private, and easy to maintain.
