Hi @Merlin-air-Q !

Thank you very much! I was able to successfully change the language, your instructions worked perfectly.

On my apps, I have the translations set up in resource files, and the operating system chooses the appropriate one based on the user's locale settings. So the appropriate language appears when you start the app. Most apps I use have the same behaviour, Air-Q is the first one I've seen that does it this way.

Thanks again for your help!

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!
