### 5/5 — Nice

*2016-06-15*

Works good.

### 5/5 — Great product - solved the problem

*2016-03-30*

I love this product. Unfortunately I still have to use a 3270 interface to handle student registrations and such at a major US university. I recently got the iPad Pro and with this app I don't have to take my computer home at night. My iPad Pro with this app solved the problem. If you still have to use 3270 interface, get this app. It is worth it....I have been using about a week and the LTE version works just fine. I may spend the $$ to upgrade but am happy with this right now.....

### 2/5 — Não abre no 3G após atualização do IOS

*2015-12-18*

Após ter atualizado o iOS, o aplicativo não abre mais no 3G. Apenas quando estou conectado a uma rede Wi-Fi.

### 5/5 — Great emulator

*2015-04-07*

Works great on my mainframe system going to upgrade to get full functions

### 4/5 — Very good terminal emulator.

*2014-05-22*

I like this app.  But recently my work has changed to SSL and have what seems to be a self-signed certificate.  This emulator does not seem to support it.  Hopefully an update will resolve this.

### 5/5 — Great!

*2013-10-07, version 2.0*

I can do last minute changes to code on the mainframe from my iphone!

### 1/5 — Why the clear Key was disabled?

*2013-08-21*

The latest update disabled the clear key, why was that??

### 1/5 — Do not upgrade!

*2013-07-25*

You will lose functionality! They turned off the PA1 and PA2 keys and didn't warn us! Bad manners!

### 1/5 — Don't upgrade

*2013-07-05*

Thanks for disabling the Clear key - now the Lite version is totally unusable!

### 1/5 — Can't connect

*2013-02-25*

Can not be configured to use ssl hence you can not connect.
