This prompted me to see what might be available for iOS... and I found GNSS View. It includes an AR (augmented reality) sky view with the present satellites.
The Chinese GNSS (GPS-equiv) satellite constellation, Beidou (pronounced roughly like "Bay Dough") is now complete and should be declared operational fairly soon: https://spaceflightnow.com/2019/12/16/china-completes-core-of-beidou-global-satellite-navigation-system/. So can you receive the signals? There's a fairly good chance that your smartphone is receiving signals and processing them into your position fixes already. Mine does not, but some other phones do. To test this on an Android phone or tablet, I suggest an app called "GPSTest". There are a number of apps with similar names, so follow this link to the Google app store: https://play.google.com/store/apps/details?id=com.android.gpstest. Look for the screen that lists satellites with flags, as below.
