I like that it allows me to send messages via email or text, which is helpful when my vet's office isn't open for business yet! It also has an option where you can leave voicemails if your doctor/vet doesn’t answer their phone right away (which happens often).
The only thing about this app was how limited some of its features were - such as not being able access certain webpages from home computers because they weren't compatible with iOS devices at all- but now those are fixed so there shouldn' be any problems anymore!! If anyone wants something similar try out other apps first before purchasing; make sure everything works properly otherwise no point in buying one since most people will have issues using them anyways after trying just once :P.
