You can update your Jobulator app via the App Store on your device.
Open the App Store and tap the "Updates" tab at the bottom of the screen.
If Jobulator does not appear in the list of available updates, it is likely that you already have the newest version installed on your device.
If a new version is available, tab the Update button for Jobulator.
The app store will then request that you enter your Apple ID password.
Enter your password and tap OK. A small icon will appear to indicate the downloading process. Once updated, tap the OPEN button to launch Jobulator and begin using the new features.
You can select the Help tab within Jobulator to verify your version. (The most recent version will appear to the right of "About Jobulator Mobile.")
