Memphian, look into the app EatSleepRide, I love it. Tracks your rides better than any app I've had and you can also search for ride routes near your location. It even tracks and records your lean angles! Don't ask me how it does it, I have no idea.
But if you're daughters were to get the app as well, you can all join a "ride group" together and it continuously shows each persons location in real-time. Another neat feature it has is called CrashLight. Somehow, if the app is running (which it would be if you're recording your ride), the app can detect a crash and immediately alert your preset contacts of your crash and your location (your daughters do not need the app to be alerted). The developer claims the app can distinguish the difference between the phone being dropped, your bike hitting a bump, etc, and a real crash. Maybe its determined by a great deceleration of speed and halted movement, I don't know, I'm not going to test it out.
In fact after typing all this out, I'd recommend the app to all our fellow riders. Anyone who does get the app, feel free to add me as rider, same handle for the app: Elroy
Edit: I looked up the CrashLight info on my app, $9.99/year. See attached photo for more info
