Oh sure, your phone just decided to nuke 40 restaurants worth of memories on its own, totally normal Tuesday behavior. That thing was probably jealous you spent more quality time with a trompo than with it. Losing 6 spots is brutal though, those are the ones you'll drive past in 3 months and go "wait, what was that place" while your friend stares at you. Bank app as a food journal is kind of genius and also kind of sad, like your debit card remembers the pho better than you do. I use Google Keep for my list and it syncs across everything, so when my phone dies the list lives on like some kind of cockroach. Just email yourself the note once a month too, takes 10 seconds and saves you from ever sitting in that parking lot again.
