A simple place for your spending.

EXP is a personal expense notebook designed around quick entry, readable history and reliable server-side storage.

Server-backed by design

Your account data is stored in the EXP application's database rather than being dependent on one browser's IndexedDB.

Built for the web and PWA

Use EXP from the website or install it as a PWA. The installed PWA is designed for a longer-lived signed-in experience.

Simple interface

The primary workflow remains intentionally lightweight: record an expense, review the day, inspect history and understand your spending.
