Any way to stop ridiculous translations in Google PlayStore?
You can force the language that app descriptions are shown in on the web version of the Play Store by changing the language code in the link. This is shown in the URL as hl=language, for example hl=en for English, hl=fi for Finnish or hl=fr for French.

So for example, to see an English description for the GMail app you'd got to this link:

https://play.google.com/store/apps/details?id=com.google.android.gm&amp;hl=en

Or in Finnish:

https://play.google.com/store/apps/details?id=com.google.android.gm&amp;hl=fi

Or to see it in French go here:

https://play.google.com/store/apps/details?id=com.google.android.gm&amp;hl=fr

Or in German go here:

https://play.google.com/store/apps/details?id=com.google.android.gm&amp;hl=de

You'll see that all that's changed between those is the &amp;hl= bit at the end of the link, yet the whole Play Store page including the description and reviews has changed to the relevant language.
