Just for those interested in how it works, when you enter a phone number in the app, it prompts the user to call a different number with the real number as a secondary parameter. The different number then calls your target number and funnels the call through them to you, while recording it in the process. You need to pay separately (per minute) to download the call recordings.

very good

Don't use this app. It charges you for recoring based on the length of the call, But doesn't gurantee if the recording will be saved. I lost some really important interview files. The support team is not responsive at all. 不要使用这一款软件，它需要你根据通话时长付费，但是不保证录音每次都能保存，我因此丢失了很重要的采访文件。他们的客服也不会回应的。非常不推荐！

Good
