Clin-e-cal is a digital health company developing smartphone apps to train and monitor inhaler use, focusing on correct technique and adherence. Using our unique Sound Response, acoustic analysis technology we have launched our first app, Rafi-Tone, aimed at helping young children accept their inhaler and allowing their parents to feel reassured. Rafi-Tone works alongside Able spacer and whistle mask which has been optimised for use with young children. We have several apps in development aimed at coaching correct technique and monitoring adherence with inhalers. Through collaborative development, this technology can provide a complete solution for two of the biggest issues in respiratory medicine in an economic and user-friendly manner.
