Illustrative participant quotations on facilitators of using mobile health (mHealth) apps for skin cancer screening

Facilitator	Participant quotation
Perceived high value of mHealth apps for skin cancer screening	‘I always feel a little burden to go to the GP, with the idea that it is actually not necessary to go to the GP.’ Participant Focus Group 4
Transparent and trustworthy identity of the app developer	‘Is there a team behind this or is it clear that an algorithm determines what’s going on? Or does it involve a real doctor or whatever?’ Participant Focus Group 1
Endorsement by healthcare providers (GPs, dermatologists) and government regulating bodies	‘… [I]f you would also give it approval because of a ministry or because of a legal regulation or something like that, this guarantee should be legal. The responsibility lies with the government with regard to its quality.’ Participant Focus Group 2
Ease of use	‘User‐friendliness is an important precondition if you want to entice people to use it.’ Participant Focus Group 2
Low (or no) cost of use	‘If my insurance company says I can use that app for free, I’m quite willing to try it.’ Participant Focus Group 2
