If you need an app that will allow you to track your hours for one or multiple jobs, may I suggest the free HoursTracker app. It’s available for both Android and iPhone.
If you head over to their website, you’ll find a video that explains how the app works front and center at the top of the page: http://www.hourstrackerapp.com/
With this app you’ll be able to use it like a time clock to clock in and out of work or enter your hours manually.
If you work multiple jobs, it’s easy to set up each place of employment and switch between them.
If your job requires reporting to a specific location, you can even set the app up to automatically log you in and out when you come and go or send a notification to remind you to log in and out.
You’ll be able to edit jobs to include the rate, expected number of hours, overtime and other information. You can set up notifications to alert you when you’ve worked your allotted time for the day.
You can also add in other information like breaks you’ve taken, tips, or mileage.
