User reviews

Nice

Works good.

Great product - solved the problem

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.....

Não abre no 3G após atualização do IOS

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

Great emulator

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

Very good terminal emulator.

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.
