U-STEP is the University of Utah vascular surgery app for patients with peripheral vascular disease. U-STEP’s assessment bundle includes patient questionnaires, fitness tests, and reports user’s passive activity through step count and GPS data from Apple’s Health Kit. The “trends” tab within the app allows patients to visualize and monitor their progress over time. To maintain up-to-date health tracking, U-STEP sends monthly reminders for patients to re-complete their assessment bundle.
