I saw a guy pitching a location based notes app years ago one morning on CNBC. I believe it was called "Acorns" (not the investment app). I was super hyped for it. Would mean the wife could just jot a note about grocery items at any point during the week and I'd get an alert whenever I got to the grocery store. Brilliant. No "don't forget milk" texts, which I forget because it's not on my actual list.
But it never launched. Or did under a new name I was unaware of. I've been waiting for location features for a long long time.
