Effects of the Kata® Inhalations-App on Inhaler Handling Errors, Adherence, and Asthma Control in Patients With Asthma.

"The Kata Inhalations-App is a digital product that bears a CE mark. The application provides algorithms to run an inhalation trainer. The inhalation trainer shows patients how to improve their inhalation maneuver in a simple and understandable way. For this purpose, the signals from the camera and microphone of the patient's smartphone are used to evaluate the individual steps of the inhalation maneuver in real-time to provide automatic, personalized feedback. Additional functions of the Kata Inhalations-App include the possibility to document health parameters and to receive inhalation reminders.~After set-up, subjects will use the application on their own as an add-on to their usual therapy for asthma. The total duration of application use will be 13 weeks, 1 week use of the Messinstrument (Measurement)-App for all subjects (Baseline period), followed by 12 weeks use of the Kata Inhalations-App (intervention) or the Messinstrument-App (control)."
