What is Angel?

The Angel app uses the same technology as our other apps, so you can get a clear audio recording of your baby’s heart beat, even if you’re not sure if you’re having a baby or not.

Our app will also record a lot of useful information for you, such as the date and time of the recording, the number of beats, and the heart rate.

How does Angel work?

Once you open the app, you will be asked to follow the instructions to get a good recording. In order to do that, you need to keep the phone in a certain position, such as flat on your stomach.
