Evaluation - methodology• Think aloud user testing

• Questionnaire

• Some personal questions

• SUS-questionnaire

• Some detailled questions about the application

Evaluation - methodology

• 7 users, 4/7 with overweight

• 21 - 25 years old

Evaluation - outcome• Adding item(s) seems hard (3/7)

• Consistency between food diary and activity logbook (7/7)

• Entering data in report view is counterintuitive (2/7)

• Many users (5/7) liked the option of challenging friends inside the application

• Some users (2/7) would have liked the option to have more than one goal; or to not have to focus on weight changes.

Evaluation - outcomeSUS - score : 81
