Doesn't work anymore
It was useful when it actually worked..
Works intermittently. When working, it does what it's supposed to with no extra gimmicks. This is nice but the only problem is its reliability. Mine hasn't updated for two weeks...
With Family Sharing set up, up to six family members can use this app.
