There are a number of third-party apps that can be used on smartphones to measure fetal heart rate. These apps typically use the phone's microphone to capture and analyze the sound of the fetal heartbeat, which is then converted into a fetal heart rate. However, the accuracy of these apps can be affected by many factors, including the quality of the microphone, ambient noise, and the app's algorithm. If you want to use such apps on your Huawei Mate60, you can search for and download them from the app store. However, these apps are not a substitute for medical-grade fetal heart monitoring devices. Therefore, Huawei mate60 can not listen to the fetal heart.
