User Reviews

Reviewers largely see Subnet Mask Calc as a free app that covers essential subnet information and can be useful for CCNA study. However, several users report serious stability issues (crashes on iOS7 and overall unusability) and a poor user interface with wasteful layout. The core functionality is appreciated, but reliability and usability are significant concerns that affect overall value.

Pros

Free to use (appears in multiple reviews).
Provides basic subnet calculation (broadcast address, first/last address, mask bits, number of hosts).
May be suitable for CCNA study / quick reference.

Cons

Stability and performance problems: crashes on iOS7 and reports of the app being unusable.
Poor and unattractive user interface: ugly / bad GUI and wasted screen space.

I ran a scan of this app through Mobileiron and the result shows that it can access the camera, contact, and microphone on my phone. Also track my geo location and could take over twitter acct. DELETE!
