2 Different ideas;
1. Locate you: An app that locates you within the hospital and on entry of the clinic name/ward directs you to where you need to be within the hospital. Time and again we see patients, visitors and even staff lost within hospital corridors, unable to comprehend the hospital maps. This is a simple app which reduces stress and late arrival to appointments.
2 - Top 5: An app that holds the top 5 frequently asked questions for the condition a patient has an upcoming doctor's appointment for. This encourages preparation of own questions based on these, promotes asking questions in the consultation (safe in the knowledge other people ask questions too!) and could have the added resource of an area to make notes or to store recorded consultations.
