This is one of the most fundamentally useful apps on my phone and I wish it existed for every computing platform in existence. It's so incredibly useful! You know what it does and it does it well. Just get it already. Worth it!
Recordings are bad I tried several of the calls after downloading the app and was disappointed in the recording. You could hear background noise, they weren't very loud on some and other birds in the background as well. Sometimes the calls are actually cut off mid call. My sister has and iPhone & has the National Geographic app and the calls were very crisp & clear. I will be removing this from my device.
