I think MaxxSpy is an excellent choice (the only choice) for parents with kids who have smartphone on Android. My kids are told they must use Wi-Fi when at all possible because with 10 devices in our home if we don't use Wi-Fi it gets very expensive. I hit the back-up to iCloud button every several days, I don't always have time to check the messages, but they're there if I want to. I have found several issues that I needed to discuss with the kids and teach them how to handle even since installing MaxxSpy.
