The PetLinx app is used in conjunction with PetLinx software (see www.petlinx.com), our professional solution for pet groomers, boarding kennels and catteries, and dog daycare businesses. It enables users of the desktop or cloud editions of PetLinx to view/edit/add their customers, pets, and bookings on their android device. Use online or offline! The PetLinx app doesn't need a data connection to be used, and will syncronize back to your main PetLinx database when you're back online. The PetLinx app requires a current PetLinx subscription. See www.petlinx.com for further information on purchasing, or email us at [email protected].
