The participant reports that sport is their main hobby, with multiple trainings, Saturday games, and gym sessions. They say Instagram use happens mostly during transport (public transport or car rides when bored, especially when others speak French) and at night at home when there is “nothing to do.” They use the banking app for restaurant payments with friends, rent, and repeated balance checks driven by curiosity. They report no screen-time limits. They recall one possible direct switch from Instagram to the banking app after seeing an Instagram ad for a Turkish group concert in Brussels and checking prices, which felt high. Emotionally, they describe stress and feeling “really bad” when checking their balance in the last two days due to spending, and guilt when Instagram use feels like wasted time. After seeing recorded daily usage (35 minutes Instagram; 25 minutes banking), they say it was higher than expected and consider deleting or reducing Instagram and reducing balance-checking.
