Bug

Téléchargé le 20/04/25 : iPhone 15, IOS 18.4 : l’application quitte presque à chaque essai lorsqu’on touche le bouton « calculer ».

It's a shame.

Good looking app, but it's not working. After the compute button is pressed it shuts down.

Does not work for me

I've got terrible echo/reverbation in part of my office room. The output from this app said it is fine and no problem detected. I hoped to be able to compare results before and after i install acoustic panels.
