Best IP Calculator Out There

IP Calc is my favorite IP calculator. The updated interface is clean, and the networking/subnet planning tools are a lifesaver for my workflow. Thanks to the developer for the thoughtful improvements-great work!

Mask slider missing

After updating to iOS 8.3, mask slider is missing. When you start the app, it's there for s second, then disappears. This is a great app, please fix. Thanks!

CIDR not present

Agreed. Following update to 8.3 CIDR is no longer visible. After entering an IP, I can no longer specify the bits to the mask.

CIDR Mask slider bar no longer visible

Up until the iOS 8.3 update, this was my IP calculator of choice. Basic calculator with CIDR slider provided 98% of my needs. Since 8.3, the slider bar is no longer visible, even though the functionality still exists.
