Tablet just for Rover app?

I use my phone. Would there be any reason that they couldn't use theirs? How are they contacting you? Are they just showing up on your doorstep?

As soon as they said they were on their way, I'd create a new stay for them and send it. The stay request arrives as quickly as a text message AND IT ARRIVES ON THEIR PHONE (for almost everyone). By the time they arrived it would only take less than a second to hit Accept on their phone when they were arriving and dropping off. With a tablet or device, each user would need to log out completely for the next user. You may run into the problem of them saying they don't remember their log-in credentials, as it's not something they are regularly asked from their phone. Besides, the stay request is already on their phone. Going forward, for those who you couldn't get payment from, I would increase the amount of the next stay to cover what wasn't paid for from the previous stay and tell them, "I'm sorry, but I cannot watch Fido until you are caught up". Once, I could almost understand but if it's become a habit then...
