Sorry to drift off topic, don't know about the Find My Friend app, but the latter about the arrow appearing next to the clock.
Any time the phone's built in GPS/location device is used, the little arrow shows up next to the clock!
Go into Settings > Privacy > Location Services. From there you can see which apps have access and have used the GPS. At the bottom, it'll tell you what each arrow colour means.
It's worth checking which "apps" have access to this, and decide whether to let them have access or not.
Sorry again to drift off track, just thought I'd drop my two cents about the "arrow"
