Digital Business Notebook is a productivity app that digitizes traditional work diaries found in stationery stores. It offers features for recording daily work hours, logging expenses and transportation costs, and managing attendance.

Users can easily record work hours, expenses, and transportation costs, including the option to register receipts and documents by taking photos. The app allows data to be exported into summary sheets and reports like work schedules in PDF or CSV formats, which can be sent to Evernote or via email.

Ideal for both employees and self-employed individuals such as freelancers needing receipt organization, this app simplifies daily work record-keeping and expense management efficiently.
