CoughDrop is a simple, modern AAC communication and support tool that empowers individuals and the teams around them. It is a full-featured communication app built for individuals with autism, cerebral palsy, Down syndrome, Angelman syndrome, Rett syndrome, or other complex communication needs. CoughDrop is flexible and configurable enough to accommodate the access and comprehension needs of many communicators. CoughDrop users can install this app to access CoughDrop's communication and reporting features on their mobile device. The app includes starter boards for different levels of communication, and boards with large or small buttons can be personalized using the rich symbol set, user-provided images or camera photos, user-recorded audio, speech synthesis, etc. CoughDrop runs on multiple devices, so you can log in on your tablet, phone and computer and have access to the same communication tools and interface. In addition, users can be linked so parents, therapists and supervisors can access a communicator's boards from their own devices to better facilitate modeling, and to make it easier to modify boards without taking away the communicator's device. The built-in reporting and messaging tools also help the support team have a consistent strategy and know what's working across locations and times.
