I like how easy it is to use and also how much info it gives me about my dogs. It's not as user friendly as I would hope for. There are some things that could be improved but overall it does what I need it to do. It helps keep track of appointments, vet visits, etc. It's very helpful to know in advance when I have an appointment. The customer service is great too. They are always willing to help. I cannot think of anything I dislike. I highly recommend this product. It has made keeping up with our appointments so much easier. We used to have to write everything down ourselves which was time consuming. Now we just open the app and go! It's a life saver.
