Place Bite Me around the craving or snack window identified in your quiz. For one person that is mid-afternoon; for another it is after dinner while settling down for the evening. The 4 PM bar shown in an example is not a rule for everyone.
Keep the bar nearby before that moment arrives, and use the app reminder at a useful time. For example, if you usually start grazing while making evening tea, having your planned portion ready can remove the decision about what and how much to have.
If the craving consistently happens earlier or later, review the timing. Follow hunger and your wider meal plan rather than waiting until you are extremely hungry. A snack schedule should also reflect how many bars your selected box includes.
