Doesn't work on iOS 10.2

Sorry, unable to select any subnet from the scroll wheel and can't calculate as a result, shame, nice interface. Needs an update and will probably be fine.

Limited use

Poor choice of shadow font makes display hard to read. Provides classful subnetting only, of little use today. Sorry developer, but not recommended.

Junk

Ignoring ip address when calc networks (e.g. 192.168.11.16/28 shows 192.168.11.0 network
(!!!)
