I love how helpful this app has been for me as well as my husband who suffers with Alzheimers, it's so easy to use! It can sometimes be glitchy but nothing major at all. I highly recommend trying this out if you are looking for something that will help assist others in memory loss issues or Alzheimer's. There isn't anything negative i dislike about their product. They have helped us tremendously throughout our journey. Having someone else take care of remembering things like appointments and reminders helps me not worry while he deals with his alzheimer's symptoms.
