 The participant describes being a professional water polo player with frequent training, Saturday night games, and morning fitness. They say Instagram and banking apps do not interfere with sport because they are not used while training, but Instagram is used during commuting and at night at home when bored. They describe banking app use as routine for paying bills and splitting restaurant costs, plus frequent “quick peeks” at their balance, which they describe as an emerging pattern and a form of feeling “addicted” to checking. They report never using screen-time limits. They estimated their usage as lower than recorded and recall one instance of switching from Instagram to banking after seeing a concert ad and finding tickets too expensive. They describe feeling bad when checking their balance after spending a lot (especially in the last two days) and guilt after Instagram when it feels like wasting time. They conclude they plan to lower both apps’ usage in the future.
