The age group 60-74 is labelled the “young elderly” and refers to people in transition from working life to retirement. Studies of mobile services have shown that young elderly customers are regarded as “not trainable” and “not interesting”. Digital wellness services for the “young elderly” with mobile technology represent a new approach to wellness. We compared wellness services on mobile smartphones and did a detailed study of one of them. We found out that standard methodology for developing digital services does not work out too well for the “young elderly” and implemented action design research.
