EduMusic - TrainMicroTuning APP
You have to set the second sound pitch making it sound like the first with the sliders.
You will see your result in cent (semitone = 100 cent).
You can also decide to tune an interval instead of the unison.
There is a Tutor mode that you can use to see in real time the pitches of the two sounds.
Good work and have fun!
