Network Toolbox App & Dept of Defense?

Delete this App. You don't need it assuming your device is not jailbroken. Update to iOS 9.3.3 and clear your Safari cache as per below:

Close Safari completely from the app switcher window by double clicking the Home button and swiping up the Safari preview pane until it disappears from the screen. Then go to Settings > Safari > Clear History and Website Data. Then do a forced restart. Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears.

Just because Apple approves the app in the App Store does not mean it is from Apple. It is from the developer that wrote it. Given that, Apple does not support the app, the developer does and could probably answer your question a lot better than someone here. See if their support can answer your question.

If you click on the link in iTunes for the developer's website, it brings you here. http://networktoolbox.de/

And from there, there seems to be a contact link at the top of the page.

This is an approved, and costly app, from Apple.

What kind of things are going on with your phone that make you think some type of software is there?

Actually it is not from Apple. Did you ask the developer what it means when this appears on your phone?

Apple hosts a store front to allow the developer to sell HIS app and take a cut of any sales, but Apple in no way will support it. The developer has identified himself to Apple, that's all he needs to do to sell the app, it doesn't even have to work, but it is his creation, not Apples.

Asked and answered; contact the developer.

My device is Not jailbroken. Glad to know.

I want to know why the DOD is listed on my iPhone. Only the developer can answer that.

This is an approved, and costly app, from Apple. To get an App approved a developer pays a fee to Apple and Apple tests it to make sure it does not contain malware. With the hundreds of thousands of apps on the store, no usability tests are done by Apple. If Apple receives a lot of negative comments about an app they reserve the right to remove.

How would you possibly know if I need it or not? See below

I know because no one needs this App, specially you since your device is not jailbroken. There are no known viruses or malware that affects iOS devices on 9.3.3 and even if they were a System Restore would resolve. iOS is a sandboxed environment.

As I suggested, update to 9.3.3 and reset Safari. If that does not solve whatever issues you are having Restore your phone as per the instructions below.

System Restore. First backup your device using iTunes. Also import your photos to your computer and copy all important data. Try restoring from backup first and testing it. If it does not help, you may have to restore as New and reconfigure from scratch as the backup could be corrupted. For this reason it is important to have your photos and data saved separately from the backup. Here are the steps for a Restore:

No, Apple does NOT support the app. The app was presumably vetted to ensure it contains no malware, but otherwise any performance or other issues with it, including interpreting the results of any scans, is the responsibility of the app vendor, not Apple.

And how does Apple provide support for the app?
