Mobile app for Client Portal

A mobile app for (at least) the client portal would be so amazing. A lot of my existing clients I’m trying to transfer over from Rover like the ease of booking from an application. The process of saving the website as a shortcut is overwhelming for my clients who work long hours or have little kids, and some who aren’t so technically literate find it difficult. I’m afraid this will get in the way of my ability to retain clients as I switch over from Rover.
