I used Spyfone to monitor my child's activity. Well, at least I did that in short periods of time, while their crappy app worked. On a non-rooted Android phone it worked for a day or so and went offline. And guess what support said to me? "You need to reinstall the app". Like, physically take the phone and reinstall it. Great job guys, but I would not need that $#*!ty app of yours if I just could get the phone my child uses any time I want to.
After a few days of explaining this simple thing to their support I asked for a refund for unused days (you can't get it for less than 3 month), and they finally fixed it. So they could do it, but of course its easier to say "just reinstall the app" then actually fix things.
Unfortunately, it worked for a day after that and gone offline again. So I asked for a refund again and they refused. Their "refund policy" covers any possible situation so spyfone.com can say "F*ck you" to any customer in any situation and just steal your money. I paid almost $200 for 2 days of app's work and a week of talking to their tech support, that's just awesome.
Take my good advice and avoid that scam app.
