Works well but eats battery

Very good app, call quality can be far better than the native cell phone app when connected to another phone with the same app or to a decent landline. Provides the status of encryption which is comforting.

This version could be improved though.

On an iPhone 5S it eats battery reserves like nothing I’ve seen.

Making a call through the app actually causes the phone to heat up almost immediately. Because this happens around the speaker it becomes uncomfortable to use.

To receive calls the app must be running. There is no background process that listens for inbound call.
