Customer Reviews

Awesome for keeping in touch with groups.

This app is great for keeping in touch with a group. Press one button and everyone knows what's gong on and has the latest info. The ability to create separate talk groups on the fly is also great for dealing with different sets of people. I can talk to everyone at once or just one person. Love that!
Most importantly I wanted a VoIP app that wasn't going to pry into my contact list and other private information like some of the others do. Highly recommend!

Awesome app

I use this app to stay connected to a radio system connected through a CriticalRF SiteCast box and it works extremely well. Allows me to hear/respond to whats going on from anywhere in the world. Would highly recommend to anyone that needs to communicate on a radio system remotely.

I wish I hadn't purchased this app.

First, it's not instant like the description says – you press the PTT button and wait 2 to 5 seconds before being told that it's ok to start talking. That was my experience on both 3G and WiFi. The second problem I noticed was very very rapid battery drain when the app is running. Third, communication takes place in talk groups but there's no apparent way to secure them from others using the app. I thought it would be an improvement over TiKL (free in the app store), but it's worse.
