No, sorry but the max. iOS version for the 3Gs is iOS 6.1.6. You cannot update it any further.
I would try to on your computer use iTunes app store and download the app
this tie it to your appleID
then on the phone go to app store and purchases->not on this phone find the app
and try to download the lastes supported version read more
Install the latest compatible version of an app on an earlier version of iOS or OS X - Apple Support
