Taffee lets you listen to your little one's heartbeats while still in the womb. At its heart is a proprietary method for reliable detection and separation of heartbeats from noisy audio.
Taffee uses a microphone sensor which is noninvasive, perfectly safe to be applied often and it even sounds more natural than an ultrasound.
Our computational approach lets tiny heartbeats come through from behind a very noisy environment, often many times louder than baby's heart sound.

Taffee lets you have your recordings organized and reproduced at the push of a button. You can also easily share them with your close ones.
Real-world microphone recordings from expectant mothers compose the first group of examples. The second group comprises results of processing several synthetic, computationally generated audio signals. Both the original and the enhanced audios have been pitch-shifted up by two octaves for a better listening experience.
Taffee uses a passive microphone sensor inspired by Pinard's horn. It only collects audible sound and no ultrasound waves are emitted, which is why you can safely use it to complement your regular checkups.
Tiny heartbeats are very gentle. What makes them even more difficult to hear are other sound sources coming from an expectant mother's belly - a very lively ambient indeed. Our algorithm is caringly engineered and adapted to separate heart signal from strong and erratic sources of noise.
Carefully designed to have low false positive rate, Taffee reliably detects presence of tiny heartbeats and will automatically tell you when you will have found the sweet spot.
Taffee processes sound signal as it streams into your mobile, on your mobile, and no network connection is required. Even more so, switching off the mobile antenna is highly recommended when using the app.
