How can I know the tuning of my accordion? Is there any app?

¿How can I know the tuning of my accordion? Is there any app that detect if the accordion is in 440, 441…hz? I recently bought a Petosa SM 300 (3/4 LMM) 3 Registers to substitute a Hohner Bravo II (2/4 MM) 2 Registers. I found the Petosa sound dryer tan the Hohner. So I would like to know the tuning difference between both of them.

"Dryer" only refers to the amount of tremolo on the MM register, not the base tuning.
There are many tuning apps (just look for "tuner") and when you play the "normal" A (which is A4) they will tell you what the tuning is.

Hello,
You can use Guitar Tuning tools to check the tuning of your accordion. (mostly on Smartphones ...)
For instance, I like very much SoundCorset

Accordeur et Métronome – Applications sur Google Play

Have a nice day !

There is also an App called "Sound Analyzer". I use the PRO version.
It can also give some indication about the tremolo (in cent) on the 8-8 (MM) register.
It is a little complicated, to set up. But it is doable.
It can be set up with the specific Chamber tone (many new accordions 442) etc.
