OneMoment is a free Android app that helps you keep track of billable hours seamlessly. This app is perfect for freelancers, hourly workers, and anyone who wants to manage their time and productivity. With OneMoment, you can log working time with just one tap, providing you with a simple and intuitive interface. You can also track multiple projects simultaneously and keep track of work time and earnings by clients, projects, and tasks.

One of the most useful features of OneMoment is the ability to generate and send a work completion report to selected clients or employers. The report can be used as completed work confirmation, billing and invoicing, and timesheet filling out. Additionally, you can set hourly rates for work to keep track of your project's proceeds and view estimated income in real-time. The app also offers intelligible reports and charts, app widgets for quick tracking, running task notifications, and project scans and documents as attachments.

Overall, OneMoment is a useful and user-friendly app for anyone who needs to keep track of their work hours and earnings. However, if you need planning options, overtime management, and notifications, you may want to try the professional version of the app, Trice.
