    Please read before you download. Try the lite version before you download the paid one. There is no magic, working of this app entirely depends on your phone's hardware. If your phone's microphone can record high fidelity sound (<150Hz) then you will be hearing the beats. We have tested this on few but it can not be tested on the entire gamut of phones this app is available on. We appreciate you downloading the app, help us remove the device from the list of supported device if it does not work on your phone by emailing us. If it does not work please try high fidelity external mic. Also in paid version you can connect your device to your laptop and listen to the recording, as laptop has better sound card there are high chances you will be able to hear the beats.
    Also please try different settings and email us filter, frequency and order that worked for you. If you are having issue using this app please give us a chance to rectify before giving a bad review.


    Baby Heartbeats is an android app designed to record fetal heartbeat with just phone's microphone. Baby's heartbeat recording can be shared with your loved ones via email, facebook, twitter etc. This application is developed for last trimester of pregnancy. It is safe to use as AIRPLANE MODE mode is mandatory which cancels all emitted waves from the device (Wi-Fi, Bluetooth, cellular, etc.), so you can use your android phone as stethoscope to hear your fetal heartbeats.
    Try before you buy, we have developed a liter version of this app. Check the preview on that before you download the paid version.
