Costly - You have to pay for each device, even if it's the same account for 1 kid.. My husband and I have the app on our phones but I go out of town a lot.. I was gonna see if my son could do it on his phone but again, they want to charge another $5.99 per month to his phone.. So $18/month for one child on 3 phones.. You should be allowed to share a medical app like this in your family.. Guess we are going to one device and see how it goes with him reaching me while out of town..
