Jaibi is an expense tracker for everyday spending. Record expenses and bills in your own categories, set budgets and see how much is left, and read reports with charts of where the money went.

Jaibi (formerly Smart Spend) is ATHRYZA's personal expense tracker. It keeps spending, bills and budgets in one place and shows the result in charts.

It is for people on a monthly salary who want to know, at any point in the month, where the money went and how much of their budget remains.

You can track expenses and bills with custom categories, set budgets and see how much is left, get a reminder before a bill is due, and review reports with charts of your spending.

The 1.7.0 update makes it easier to start and quicker to use. You can start as a guest with no sign-up and sign in later from Settings to back up and sync your data. The add screen is quicker: the merchant is optional and your last category is remembered. An optional evening reminder prompts you to log the day. The app also has a new icon.

Available on Google Play and the App Store.

ATHRYZA designed, built and published Jaibi and maintains it on both stores.
