Expense Ninja is a private expense tracker for iPhone and Android. Snap a receipt or add the spend yourself. The scan reads the merchant, total, date, and category on your phone, and you check them before you save.

Home shows recent spending and your top categories. Search the list, or filter by date, payment, and category. Open any expense to edit or delete it, and add your own categories. Monthly budgets and alerts keep the month in view, and Insights show where the money went.

Set your currency, language, and a light or dark theme. Expenses, budgets, and receipt details stay on the device. Signing in only identifies your account. It does not upload the ledger.

Point the camera at a receipt, follow the guide, and save a clean expense. Coffee, groceries, invoices, and travel land in the same list. It is built for students, freelancers, travelers, and households who want the month without a spreadsheet.

Free includes scanning, manual entry, home, budgets, insights, search, and filters: up to 10 categories, 5 manual expenses a day, and 3 scans a day. Premium removes those caps and converts a foreign receipt into your currency at today’s rate. There is a 7-day free trial. Cancel anytime in the App Store or Google Play. Delete one expense whenever you want, or remove the account and the data on that phone from Settings.
