Has your headset somehow changed the date to 203X or something? Can you not access the internet or any of your other apps? This app can help. It allows you to open the inbuilt android settings screen where you can access date/time settings to fix the problem.

It has been created as some Vendors have hidden or removed the link to open Android's settings.

If you have the 'Settings' app listed in your app drawer then this app has no purpose for you. In some cases this app may not work for you at all.
