Independence and dignity are important to seniors. But anyone with a parent living alone understands the daily anxiety and stress of worrying whether Mom, or Dad(!), is OK. StackCare uses discrete motion sensors and artificial intelligence to learn individual behavior and activity patterns, sending notifications directly to your phone. You get to see at a glance, simply and easily, if your loved one is sleeping ok, is visiting the bathroom too often, whether his/her activity patterns have changed, or even seeing the house temperature to make sure everything is set for the ideal climate. StackCare’s easy to use app will give you the information to know if everything looks normal or if maybe you need to check in on Mom/Dad. They keep their independence, you get peace of mind. This app connects to the StackCare remote monitoring system (available at www.stack.care).
