NeedFood SG is an app for people who don't cook and who can only remember the number for Pizza Hut.
It's a directory of places that deliver around Singapore. Apart from the usual suspects like Pizza Hut and Dominos, it also covers Japanese, Chinese, Indian and Western restaurants that deliver.
The app allows you to call the restaurant and will tell you the delivery fee but there is no menu or information about delivery restrictions (some places won't deliver if you're too far away from them).
NeedFood SG costs US$0.99 You can download it here.
