Research question	Summary of core results
1	A need for support was determined. Receiving more educational health information, increased support in the form of prescribed medication, and help in terms of implementing supervised exercise therapy (SET) are the most desired actions for improving the care of patients with PAD.
2	Half of the participants use smartphones. For them, mobile interventions to support SET and medication can be a relevant treatment component. Patients aged >70 years are less likely to use smartphones than younger patients. With regard to characteristics such as sex, education, profession, BMI, smoking behavior, exposure to illness or the environment, or the current state of illness, the data did not reveal any significant differences between smartphone users and nonusers within the patient population.
3	Interest in smartphone-supported training is present, even for people who do not currently use a smartphone. Health app components such as “information,” “monitoring,” and “feedback” were the most relevant for patients with PAD. Other components such as “choosing goals,” “interaction with physicians and therapists,” “interaction with other patients,” and “reminders and suggestions for goal setting” were less relevant for the patients and should be selectable on demand according to patient preference.
