Share location between iOS and Android..? My wife and I find it really useful to share our locations with each other. Until now we both had iPhone's and were using the "Find my friends" app, but my wife is now using Android (Samsung S8).

I've looked at the "Trusted Contacts" app, but that only seems to share the location temporarily. We want to share locations permanently, without manually authorising all the time, and without annoying notifications.

Is there any way,  that works on both platforms to permanently share your location with someone else ?
Google maps has live location sharing, built in. 

It works for both, iPhone and Android devices according to Google support

You can set it up in just a few steps:

Open Google maps, in the menu, select location sharing. There, it will ask how long you want to share your location for.  Select until you turn this off and choose an email account to share it with. (Both have to have a Google account to use this feature)

The same is done on an iPhone after downloading Google maps.

Now, every time you open Google maps, it will show you exactly where the other person is located.
