Initially I wanted to do an iPhone and Android app but couldn't decide on an app that wasn't just recreating the experience of the delivery.com app already available on both platforms.
While studying the api I began thinking about things that could enhance the user's experience on delivery.com and came across last_or_next_order_time in the /merchants response.
Then the idea came. Why not make a Pebble app that notifies you when the next wine/liquor store is available for delivery. This app could be installed by anybody even if they don't have a delivery.com account.
My target user is someone that just wants to know when the next delivery time is without needing to bother pulling out their phone.
The app functions as a normal watch telling you the current time and also displays the next delivery time.
