Useless

Opens up on with the mic running and starts to register frequencies before the belt is plucked. Far too sensitive. Very inconsistent readings. No way to clear all frequencies already recorded. Total waste of time.

Easy belt tension

Thanks for the free app. Used on cvt v belt and timing belts. Clear instructions now ensure good measurements.

Stürzt immer ab

Stürzt ab bevor jemals irgendein Geräusch aufgenommen wurde. Konnte es noch nie starten. Wieder gelöscht

Terribly unreliable

I’m an audio engineer and I know for a fact that a carbon belt would not vibrate at 20,30,40,50,70,80 Hz with subsequent twangs. It must be reading the higher harmonics.

OK

Trzeba trochę wprawy i naprawdę cichego pomieszczenia, wtedy daje powtarzalne i wiarygodne wyniki. Dolną część telefonu (gdzie znajduje się mikrofon) ustawić bardzo blisko paska, tam gdzie nim szarpiemy. Pasek ustawiony idealnie :)
