Babybeat Tracker on Windows Phone (measures fetal heart rate)June 25, 2013 1 Comment
Here is a pretty interesting app called Babybeat Tracker. The app suupedly (had no way of testing) listens and reads a fetal heart rate by using your phone’s microphone.
- Calibration to adjust microphone sensitivity according to the used phone
- Visible heartbeats can be monitored
- Simulated fetal doppler sound is generated after the heart rate is measured
- Live tile shows the last measurement
- Airplane mode detection and turning on
The developers also have a similar app on the Windows Phone Store that can measure everyone else’s heart rate.
With Babybeat Tracker you can measure fetal heart rate by using your phone’s microphone. During measurement heartbeats are drawn. After the heart rate is measured, corresponding simulated fetal doppler sound can be listened. Measured heart rate can be saved to results. Graph of results can be viewed.
Heart rate can be measured in two ways. The first way is to position the microphone like a doppler device (on your belly). Quiet environment is needed. This measurement way can be used from about week 27, but every pregnancy is individual. Fetal position also affects to how easily heart rate can be measured.
The second way is good if you own a home doppler device, but don’t know fetal heart rate. Pulse can be measured from pre-recorded doppler audio or directly from home doppler device’s speaker.
Important note concerning the model of the phone:
With some phones it is difficult to use Babybeat Tracker when measuring directly on belly. For example Lumia 920 with three microphones and effective noise cancelling algorithms (HAAC technology) easily filters heartbeats off. Also other WP8 Lumia phones with HAAC technology are not the best phones to be used with this app. However, heartbeat can be detected if heart rate is measured with the top microphone. On the other hand, for example in Lumia 800 it is very easy to find heartbeat. Try Babybeat Tracker with your phone and give feedback.
