After a quick look on the Play Store, all the apps that I can find are pay-only, freemium, and cloud or AI powered.

(spoiler: infrasound can be detected and translated offline and without using any AI models)

Luckily we have alternatives to the Play Store.

It looks like F-Droid does not have any apps matching the search string "Infrasound"

Well, that's all I have time for now.
