- if I could add my shopping list automatically to my Tesco basket to get my weekly groceries delivered that would be AMAZING - friendly and approachable feel, more 'common sense' driven, less data driven (no charts and graphs, and calories goals etc) - plan your next workout after completing one is a good piece of behavioral design a) making an explicit commitment increases the likelyhood of following up b) good timing to ask that question - I feel accomplished after completing a workout which makes me want to do it again - progressing from e.g. novice to intermediate level with my exercise routine gives me a sense of accomplishment
