Ausculto: Vibration & Noise

Ausculto is a stethoscope for the machines in your home. Put the phone on the washing machine, the fridge, the car bonnet or the PC fan: using the microphone and the accelerometer, Ausculto learns how the machine sounds and vibrates while it is healthy. In later checks it compares and tells you, in plain words, whether something has changed. • The fingerprint: the first checks become the reference for the machine in good condition • Health score from 0 to 100 and a trend over time for each machine • Clear report: new tones, whistles, more high-frequency energy, knocks, rising vibration, slower revolutions • Before / now listening: play the fingerprint and the latest check one after the other • Live spectrogram: see the sound, with the main note and frequency • Vibration meter in mm/s with ISO 10816 zones • Tachometer: RPM of fans and motors, without touching them • Spirit level: level your washer and fridge so they vibrate less • Tips on where to place the phone for each kind of machine • In 10 languages Many faults give warning weeks in advance: a wearing bearing adds knocks and hisses, an imbalance makes things vibrate more, a slipping belt lowers the revolutions. Ausculto helps you notice before it becomes a breakdown. Free with 2 machines, spectrogram and spirit level. With a short video, if you like, you unlock Premium until the app is closed: unlimited machines, vibration meter, tachometer and before / now listening. No purchases. No account and no server: recordings and measurements stay on your phone. A phone is not a certified measuring instrument: values are indicative and the diagnosis is up to a technician.
