As usual, Lonelysandwich (aka. Adam Lisagor)’s video is hilarious and makes you want to buy the product right away (remember the Jambox?). Checkmark is a soon-to-be-released iPhone app which makes setting (and forgetting – for now) location-based reminders easy, and effective.
Sick of forgetting to pick up that [insert household item here] every damn time you visit the grocery store? You need Checkmark.
