Excellent Security and Information Utility

Happy long-time user of Neptune Security and the developer is regularly updating for currency. In addition to a very detailed Device information tab, there’s an Orbit tab that shows all a summary of all the devices you have Neptune installed on. I did note a minor bug where it reports my firmware is out of date on an iPod Touch 7th Gen; I already have the latest iOS version (15.0.2) installed.

Intrusion on app

To the developers and users of this app, just to raise awareness I was involved in an identity theft and Cyber Connectix crime. I did report incident with governmental authorities since we are potential or actual victims of cyber crime whether on IOS or IP, i reviewed this product to ensure the safety of my personal information and privacy from being exposed. In the attempt of sending an email unfortunately it prevented me from doing so, too also include noticing that the app has some discrepancies. The device name does not match up with the device itself, meaning upon utilizing the app I noticed in the device category device name stated iPhone8 even though I have an iPhone 6s; secondly I took a snapshot picture where the remote section part of the app as it was loading it showed 2 devices connected even though this is the only device I have that is only authorized to be utilized, so even though because of this intrusion it also notified me which gave me enough evidence to support my case. I also have other programs that I am using to better secure my phone but honestly anything can be bypassed. I hope this review helped anyone and including the developers to ensure their security system is updated without losing any sort of credibility on their product.

Beware! There’s no way to contact Neptune’s developer for support!

Before buying this app, click on the button on Neptune’s page here in the App Store to contact support/the app developer. You’ll see that Neptune doesn’t provide a legitimate app/company/developer website link, email address or even a social media account for customers to get in touch with the developer for questions or troubleshooting. I was able to track the developer down on Twitter when I had a question about Neptune after I purchased it. But he hadn’t tweeted in over a year so of course my question was never answered.

Apps, especially ones customers have to pay for, should offer a point of contact for customers’ support needs. This app not only fails to do that, but it intentionally gives fake contact info on the app’s page in the App Store to confuse and deceive its customers.
