### 2/5 — Doesn’t recognize IP addressed

*2022-10-18*

I have used this app for a while and found it useful, until today.  I put in several IP addresses - 10.12.131.96/28 and others, and it asks me to enter a valid IP address.  Tried restarting and reloading the app and still get the same message

### 4/5 — 4 stars until I can purchase app..

*2019-12-05*

i downloaded this app a few weeks ago & it sat for a minute on the shelf until today. first off, there are a ton of features offered on the free app. living on a returning college graduate budget, this app is a nice chunk of gas/food money but i really dig how the developer lets u know exactly what ur paying for. i plan on purchasing this app on payday soon.

### 2/5 — Would be a nice utility but ....

*2019-08-14*

I can’t for the life of me think of a reason why this app needs to have an active internet connection in order to do simple subnet calculations. What days does it need to send or receive?
I don’t always work in areas where Mobile Data is available, or WiFi, so for areas like that this app is useless. For those of us security conscious enough to not allow every single app on their phone access to Mobile Data unless there is a valid reason, this is useless.
I’ve given two stars because it’s a nice app when it works but it’s lost three because of the inability to do anything without any internet connection.

### 3/5 — It’s ok......

*2018-08-07*

Wasn’t hopeful that this would be anything special, and wasn’t disappointed. Well perhaps a little! Biggest issue for me is that keyboard for entering IP address doesn’t have a . so you have to click on the next octet to move forward.

### 1/5 — One star

*2018-01-24*

Agree with some terms for a calculator? Really?!
Uninstalled immediately
