An expense tracker only works if logging takes seconds. With this expense tracker app maker you describe the flow you will actually use every day, your categories and your currency, the AI agent writes the app, you log a few entries in the emulator preview and download the APK. No bank links, no ads, no account: just your spending, on your phone.
What your expense tracker app will have
From the idea above, the agent builds:
- Quick add — a plus button, a large number keypad, then one tap on a category. Note and date are optional.
- Home — this month's spending, income and what is left, with a donut chart by category.
- Categories — Food, Transport, Rent, Bills, Shopping, Health, Fun and Other, each with an icon and color you can change.
- History — entries grouped by day, a search box and a month filter.
- Edit and undo — swipe to edit or delete, with an Undo button so nothing is lost by accident.
- Settings — currency, number format, first day of the month and a dark theme.
Everything is saved on the phone, so the tracker opens instantly and works offline.
Features you can ask for
- Recurring entries for rent, subscriptions and loan payments, logged once.
- Monthly budgets per category with a progress bar that turns red.
- A Reports tab: six-month bar chart and your top categories.
- A receipt photo on each entry, taken with the camera on your phone.
- Export to CSV and a backup file you can restore on a new phone.
- A monthly summary in plain words ("You spent more on food than last month") written by AI, using the AI backend that comes with the project.
- A daily reminder in the evening to log the day's spending.

Get it on your phone
- Press Build this expense tracker app and sign in with Google.
- Log a week of real expenses in the emulator preview. Notice what feels slow.
- Ask for changes in plain words: "remember my last category", "bigger category buttons", "show income in green".
- Press Download APK and install it on your Android phone.
- For Google Play, build the signed APK and AAB from the same menu; the APK builder page explains the steps.
Start with eight categories or fewer. Every extra category is one more decision per entry, and slow logging is the main reason people stop tracking.
Why build your own expense tracker
Store apps try to be everything: bank syncing, investment tips, upsells. Most people want something much simpler: a fast way to note "250 for lunch" and see where the month went. Building your own gives you exactly that, in your currency and your categories, with charts you actually read. It is also private by design, because the data stays on your phone unless you choose otherwise. And when your needs change, such as a new budget or a trip, the change is one message to the agent instead of a hunt for a different app.
Frequently asked
Is my spending data private?
Yes. A simple expense tracker stores everything on the phone, with no login and no server. Nothing leaves the device unless you ask for sync with a hosted backend or share an export yourself.
Can I use my own currency and categories?
Yes. Name your currency and your categories in the request, or change them in the app's settings later. The agent formats amounts the way your country writes them.
Can two people share one expense tracker?
Yes. For a couple or flatmates, ask for a hosted backend with sign-in. The online database comes with the project, and each person sees the same entries on their own phone.
Can the app remind me to log expenses?
Yes. Ask for a daily reminder at a time you choose. It is a local notification that fires on your Android phone even when the app is closed; in the emulator preview you trigger it from the Simulate panel.
How do I install it?
Press Download APK in the builder, open the file on your Android phone and allow installs from your browser once.
