I recently purchased the Air-Q Science sensor. I really like the way the various measurements are presented in the iOS app.
One problem for me though is that the app is in the German language only, which I am not a speaker of. Right now I take a screenshot and have my iPhone running iOS 26 translate the screenshot. It's a cumbersome process, but it works.
As an iOS/Android developer myself I know that these platforms make it very easy to translate the text of an app in multiple languages. There are several online platforms that allow a developer to easily upload all the text included in the app, have it translated and incorporate those translations back in the app. The text can be cheaply translated using machine translations, or more expensively, by using real humans do it.
Would it be possible to add an English translation in the app? Perhaps you want to add other common languages used within EU while you're at it.
Thanks!
